The '''[[phonology]] of [[Irish language|Irish]]''' varies from [[Irish language#Dialects|dialect to dialect]]; there is no [[standard language|standard pronunciation]] of the language. Therefore, this article focuses on phenomena that pertain generally to most or all dialects, and on the major differences among the dialects.
'''[[Phonology]]''' here refers to the sound patterns of the [[Irish language]], which vary by [[dialect]] but share certain features. Phonologists have traditionally classified most of the [[language]]'s 33 or so [[consonant]]s into 'broad' and 'slender' pairs, i.e. respectively [[velarization|velarised]] or [[palatalization|palatalised]], involving different placement of the [[tongue]]. This difference is ''[[phoneme|phonemic]]'': substituting one for another produces a different [[word]], e.g. ''bó'' 'cow' and ''beo'' 'alive'. Such consonants also affect which of Irish's 15 or so [[vowel]]s may acceptably co-occur with them.


Irish phonology has been studied as a discipline since the late [[nineteenth century]], with numerous researchers publishing [[descriptive linguistics|descriptive]] accounts of dialects from all regions where the language is spoken. More recently, [[theoretical linguistics|theoretical linguists]] have also turned their attention to Irish phonology, producing a number of books, articles, and doctoral [[thesis|theses]] on the topic.
Another interesting feature of Irish phonology concerns [[consonant cluster]]s, i.e. sequences of consonants. Words may begin with two or three consonants, which usually agree in being broad or slender. Two-member clusters consist of an [[obstruent|obstruent consonant]] followed by a [[liquid consonant|liquid]] (e.g. ''pleidhce'' /ˈpʲlʲəicə/ 'idiot') or [[nasal consonant]] (e.g. ''cnaipe'' /ˈkn̪ˠapʲə/ 'button'); three-member clusters start with a [[sibilant consonant|sibilant]] as in ''sparán'' /ˈsˠpˠaɾˠaːn̪ˠ/ 'purse', preceding a [[voicing|voiceless stop]] and a liquid.<ref>Ní Chiosáin (1999).</ref> However, under ''[[consonant mutation]]'' (changing consonants according to some rule), other sequences can occur: e.g. ''bhlas'' [wɫ̪asˠ] 'tasted', ''mbláth'' [mˠɫ̪aː] 'flower'.<ref>Ní Chiosáin (1999); Ó Sé (2000: 33).</ref>


One of the most important aspects of Irish phonology is the fact that almost all [[consonant]]s appear in pairs, with one member of each pair being 'broad' and the other 'slender'. Broad consonants are [[velarization|velarised]], that is, the back of the [[tongue]] is pulled back and slightly up in the direction of the [[soft palate]] while the consonant is being [[articulatory phonetics|articulated]]. Slender consonants are [[palatalization|palatalised]], which means the tongue is pushed up toward the [[hard palate]] during the articulation. The contrast between broad and slender consonants is crucial in Irish, because the meaning of a [[word]] can change if a broad consonant is substituted for a slender consonant or vice versa. For example, the only difference in pronunciation between the words ''bó'' 'cow' and ''beo'' 'alive' is that ''bó'' is pronounced with a broad ''b'' sound, while ''beo'' is pronounced with a slender ''b'' sound. The contrast between broad and slender consonants plays a critical role not only in distinguishing the individual consonants themselves, but also in the pronunciation of the surrounding [[vowel]]s, in the determination of which consonants can stand next to which other consonants, and in the behaviour of words that begin with a vowel.

Irish shares a number of phonological characteristics with its nearest linguistic relatives, [[Scottish Gaelic language|Scottish Gaelic]] and [[Manx language|Manx]], as well as with [[Hiberno-English]], the language with which it is most closely in [[language contact|contact]].

==History of the discipline==
'I have heard tell that we'll have a wet summer this year, but it seems to me that that story is strange.'


Until the end of the [[nineteenth century]], linguistic discussions of Irish focused either on the traditional [[grammar]] of the language (issues like the [[inflection]] of [[noun]]s, [[verb]]s and [[adjective]]s) or on the [[historical linguistics|historical]] development of sounds from [[Proto-Indo-European language|Proto-Indo-European]] through [[Proto-Celtic language|Proto-Celtic]] to [[Old Irish language|Old Irish]]. The first [[descriptive linguistics|descriptive]] analysis of the phonology of an Irish [[dialect]]<ref>Finck (1899).</ref> was based on the author's fieldwork in the [[Aran Islands]]. This was followed by a phonetic description of the dialect of Meenawannia near [[Glenties]], [[County Donegal]].<ref>Quiggin (1906); for a predominantly historical account, but with some description of modern dialects, see also Pedersen (1909).</ref> [[Alf Sommerfelt]] published early descriptions of both Ulster and Munster varieties<ref>Sommerfelt (1922) and Sommerfelt (1965) for the village of Torr in [[Gweedore]]; Sommerfelt (1927) for Munster.</ref> and  for the now extinct dialect of South [[County Armagh|Armagh]]).<ref>Sommerfelt (1929).</ref> The dialect of [[Dunquin]] on the [[Dingle Peninsula]] has also been described.<ref>Sjoestedt (1931)</ref>. From 1944 to 1968, the [[Dublin Institute for Advanced Studies]] published a series of [[monograph]]s, each describing the phonology of one local dialect: West Muskerry in [[County Cork]] ([[Ballyvourney]], [[Coolea]] and vicinity),<ref>Ó Cuív (1944).</ref> Cois Fhairrge in [[Connemara]] ([[Barna]], [[Spiddal]], [[Inverin]] and vicinity),<ref>de Bhaldraithe (1966): first published 1945.</ref> [[Ring, County Waterford|Ring]] in [[County Waterford]],<ref>Breatnach (1947).</ref> for [[Tourmakeady]] in [[County Mayo]],<ref>de Búrca (1958).</ref> [[Teelin]] in [[County Donegal]],<ref>Wagner (1959).</ref> and [[Erris]] in [[County Mayo]].<ref>Mhac an Fhailigh (1968).</ref> More recent descriptive phonology has been published for [[Rosguill]] in northern Donegal,<ref>Lucas (1979).</ref> Iorras Aithneach in [[Connemara]] ([[Kilkieran]] and vicinity),<ref>Ó Curnáin (1996).</ref> and the [[Dingle Peninsula]] in [[County Kerry]].<ref>Ó Sé (2000).</ref>

Recent research into the theoretical phonology of Irish followed the principles and practices of ''[[The Sound Pattern of English]]'' (''SPE'').<ref>i.e. Chomsky & Halle (1968) was used by Ó Siadhail & Wigger (1975); this work formed the basis of the phonology sections of Ó Siadhail (1989).</ref> Dissertations examining Irish phonology from a theoretical point of view have used ''[[Optimality Theory]]''<ref>Ní Chiosáin (1991); Green (1997).</ref> and ''[[government phonology]]''.<ref>Cyran (1997); Bloch-Rozmej (1998).</ref>
 
==Consonants==
Most dialects of Irish contain at a minimum the consonant [[phoneme]]s shown in the following chart (see [[International Phonetic Alphabet]] for an explanation of the symbols). Symbols appearing in the upper half of each row are [[velarization|velarised]] or 'broad', while those in the bottom half are [[palatalization|palatalised]] or 'slender'. The consonant /h/ is neither broad nor slender.

====Stress====
===On- and offglides===
[[Stress (linguistics)|Stress]] is generally predictable in Irish: it is placed on the first [[syllable]] of the word, e.g. ''easonóir'' [ˈasˠən̪ˠoːɾʲ] 'dishonour'.<ref>Stress is indicated by [ ˈ ] immediately before the stressed syllable.</ref> Exceptions are often [[adverb]]s or [[loanwords]], such as ''amháin'' [əˈwaːnʲ] 'only' and ''tobac'' [təˈbak] 'tobacco'. In [[compound (linguistics)|compund]] words, such as ''lagphórtach'' [ˈɫ̪agˌfˠɔɾˠt̪ˠəx] 'spent bog', primary stress falls on the first member. When a short vowel is unstressed, it generally surfaces as the [[schwa]] [ə], similar to the vowels beginning and ending the English word ''aroma''.
Broad (velar or velarised) consonants have a noticeable [[velar approximant|velar offglide]] (a very short vowel-like sound) before [[front vowel]]s, which sounds like the English ''w'' but made without rounding the lips. The IPA symbol for this sound is [ɰ]. Thus ''naoi'' /n̪ˠiː/ 'nine' and ''caoi'' /kiː/ 'way, manner' are pronounced [n̪ˠɰiː]) and [kɰiː],<ref>Sjoestedt (1931: 19).</ref><ref>Sutton (1993).</ref> This velar offglide is [[labialization|labialised]] (pronounced with lip-rounding, like ''w'') after [[labial consonant]]s, so ''buí'' /bˠiː/ 'yellow' is pronounced [bˠwiː].<ref>Sutton (1993); Quiggin (1906: 76).</ref> Similarly, slender (palatal or palatalised) consonants have a [[palatal approximant|palatal offglide]] (like English ''y'') before [[back vowel]]s, e.g. ''tiubha'' /tʲuː/ "thick" is pronounced [tʲjuː].<ref>Ó Sé (2000: 11).</ref>
 
When a broad consonant follows a front vowel, there is a very short vowel sound [ə̯]) (called an ''onglide'') just before the consonant, e.g. ''díol'' /dʲiːɫ̪/ 'sell' is pronounced [dʲiːə̯ɫ̪/]. Similarly, when a slender consonant follows a back vowel, there is an onglide [i̯] before the consonant, e.g. ''áit'' /aːtʲ/ 'place' is pronounced [aːi̯tʲ]),<ref>Ó Sé (2000: 11); de Bhaldraithe (1966: 43).</ref> ''óil'' /oːlʲ/ 'drinking' ([[genitive]]) is pronounced [oːi̯lʲ],<ref>de Búrca (1958: 59).</ref> ''meabhair'' /mʲəuɾʲ/ 'understanding' is [mʲəui̯ɾʲ],<ref>Mhac an Fhailigh (1968: 46).</ref> ''dúinn'' /d̪ˠuːn̠ʲ/ is [d̪ˠuːi̯n̠ʲ].<ref>Sommerfelt (1922: 150).</ref>
 
===Allophones===
/w/ has two basic [[allophone]]s: the [[labiovelar approximant]] [w]) and the velarised [[voiced labiodental fricative]] [vˠ]). The distribution of these allophones varies from dialect to dialect. In Munster generally only [vˠ]) is found,<ref>Sjoestedt (1931: 28–29)</ref> and in Ulster generally only [w].<ref>Quiggin (1906: 74–76).</ref> In Connacht [w] is found word-initially before vowels (e.g. ''bhfuil'' [wɪlʲ] 'is') and [vˠ] in other positions (e.g. ''naomh'' [n̪ˠiːvˠ] 'holy', ''fómhar'' [ˈfˠuːvˠəɾˠ] 'autumn', ''bhrostaigh'' [ˈvˠɾˠɔsˠt̪ˠə] 'hurried'.<ref>Finck (1899: 64–67); de Bhaldraithe (1966: 30–31).</ref>
 
The labiodental fricatives /fˠ, fʲ, vʲ/ as well as the fricative allophone [vˠ] of /w/ have bilabial allophones [ɸˠ, ɸʲ, βˠ, βʲ] in many dialects; the distribution depends partly on environment (bilabials are more likely to be found adjacent to rounded vowels) and partly on the individual speaker.<ref>de Bhaldraithe (1966: 31–32).</ref>
 
The alveopalatal stops /tʲ, dʲ/ may be realized as [[affricate]]s [tɕ, dʑ] in a number of dialects, including Tourmakeady.<ref>de Búrca (1958: 24–25).</ref> Erris,<ref>Mhac an Fhailigh (1968: 36–37).</ref> and Teelin.<ref>Wagner (1959: 9–10).</ref>
 
The palatal stops /c, ɟ, ɲ/ may be articulated as true palatals [c, ɟ, ɲ] or as [[velar consonant|palatovelars]] [k̟, ɡ˖, ŋ˖].<ref>Ó Sé (2000: 14–15, 18).</ref>
 
The phoneme /j/ has three allophones in most dialects: a [[palatal approximant]] [j] before vowels besides /iː/ and in at the ends of [[syllable]]s (e.g. ''dheas'' [jasˠ] 'nice', ''beidh'' [bʲɛj] 'will be'); a [[voiced palatal fricative|voiced (post)-palatal fricative]] [ʝ] before consonants (e.g. ''ghrian'' [ʝɾʲiən̪ˠ] 'sun'; and an intermediate sound [j˔] (with more [[fricative consonant|frication]] than [j] but less frication than [ʝ]) before /iː/ (e.g. ''dhírigh'' [j˔iːɾʲə]) 'straightened'.<ref>Breatnach (1947: 39–40); Ó Cuív (1944: 42–43); de Bhaldraithe (1966: 34); Mhac an Fhailigh (1968: 34–35).</ref>
 
As in [[English language|English]], [[voice (phonetics)|voiceless]] [[stop consonant|stops]] are [[aspiration (phonetics)|aspirated]] (articulated with a puff of air immediately upon release) at the start of a [[word]], while voiced stops may not be fully voiced but are never aspirated. Voiceless stops are unaspirated after /sˠ/ and /ʃ/ (e.g. ''scanradh'' [sˠkauɾˠə]<ref>Pronounced as if spelt ''scamhradh''; see [[orthography of Irish]].</ref> 'terror'); however, stops remain aspirated after the [[clitic]] ''is'' /sˠ/ (e.g. ''is cam'' [sˠkʰaum] 'it's crooked'.<ref>Breatnach (1947: 33, 76).</ref> Several researchers<ref>e.g. Ó Cuív (1944); Wagner (1959); de Bhaldraithe (1966); Mhac an Fhailigh (1968); Ó Sé (2000).</ref> use transcriptions like /sb sd sg xd/, etc., indicating they consider the stops that occur after voiceless fricatives to be devoiced allophones of the voiced stops rather than unaspirated allophones of the voiceless stops, but this is a minority view.
 
===Fortis and lenis sonorants===
In [[Old Irish language|Old Irish]], the coronal [[sonorant]]s (those spelled ''l n r'') were divided not only into broad and slender types, but also into [[fortis and lenis|''fortis'' and ''lenis'']] types. The precise [[phonetics|phonetic]] definition of these terms is somewhat vague, but the fortis sounds were probably longer in duration and may have had a larger area of contact between the tongue and the roof of the mouth than the lenis sounds. By convention, the fortis sounds are transcribed with [[capital letters]] /L N R/, the lenis with lower case /l n r/. Thus Old Irish had four [[rhotic consonant|rhotic]] phonemes /Rˠ, Rʲ, rˠ, rʲ/, four [[lateral consonant|lateral]] phonemes /Lˠ, Lʲ, lˠ, lʲ/, and four coronal [[nasal consonant|nasal]] phonemes /Nˠ, Nʲ, nˠ, nʲ/.<ref>McCone (1994: 90).</ref> Fortis and lenis sonorants contrasted with each other between vowels and word-finally after vowels in Old Irish, for example ''berraid'' /bʲeRˠɨðʲ/ 'he shears' vs. ''beraid'' /bʲerˠɨðʲ/ 'he may carry'; ''coll'' /koLˠ/ 'hazel' vs. ''col'' /kolˠ/ 'sin'; ''sonn'' /sˠoNˠ/ 'stake' vs. ''son'' /sˠonˠ/ 'sound'. <ref>Quin (1975: 4–5).</ref> Word-initially, only the fortis sounds were found, but they become lenis in environments where [[morphosyntax|morphosyntactically]] triggered lenition is found: ''rún'' /Rˠuːnˠ/ 'mystery' vs. ''a rún'' /a rˠuːnˠ/ 'his mystery', ''lón'' /Lˠoːnˠ/ 'provision' vs. ''a lón'' /a lˠoːnˠ/ 'his provision'.<ref>Quin (1975: 8).</ref>
 
In the modern language, the four rhotics have been reduced to two in all dialects, /Rˠ, Rʲ, rˠ/ having merged as /ɾˠ/. For the laterals and nasals, some dialects have kept all four distinct, while others have reduced them to three or two distinct phonemes, as summarised in the following table.

==Vowels==
The [[vowel]] sounds vary from dialect to dialect, but in general Connacht and Munster at least agree in having the [[monophthong]]s /iː/, /ɪ/, /uː/, /ʊ/, /eː/, /ɛ/, /oː/, /ɔ/, /a/, /aː/, and [[schwa]] (/ə/), which is found only in [[stress (linguistics)|unstressed]] syllables; and the [[diphthong]]s /əi/, /əu/, /iə/, and /uə/. The vowels of [[Ulster Irish]] are more divergent.
 
===Vowel backness===
The [[vowel backness|backness]] of vowels (that is, the horizontal position of the highest point of the tongue) depends to a great extent on the quality (broad or slender) of adjacent consonants. Some researchers<ref>e.g. Ó Siadhail & Wigger (1975: 80–82); Ó Siadhail (1989: 35–37); Ní Chiosáin (1994).</ref> have argued that [ɪ] and [ʊ] are actually allophones of the same phoneme, as are [ɛ] and [ɔ]. Under this view, these phonemes are [[underspecification|not marked]] at an abstract level as either [[front vowel]]s or [[back vowel]]s. Rather, they acquire a specification for frontness or backness from the consonants around them. In this article, however, the more traditional assumption that /ɪ, ʊ, ɛ, ɔ/ are four distinct phonemes will be followed.<ref>The descriptions of the allophones in this section come from Ó Sé (2000: 20–24); the pronunciations therefore reflect the Munster accent of the [[Dingle Peninsula]]. Unless otherwise noted, however, they largely hold for other Munster and Connacht accents as well.</ref>
 
====Close vowels====
The four [[close vowel]] phonemes of Irish are the fully close /iː/ and /uː/, and the [[near-close vowel|near-close]] /ɪ/ and /ʊ/. Their exact pronunciation depends on the quality of the surrounding consonants. /iː/ is realised as a [[front vowel|front]] [iː] between two slender consonants (e.g. ''tír'' [tʲiːrʲ] 'country'). Between a slender and a broad consonant, the tongue is retracted slightly from this position (for which the IPA symbol is [i̠ː]), e.g. ''díol'' [dʲi̠ːɫ̪] 'sale', ''caoire'' [ki̠ːɾʲə] 'berry' (genitive). Between two broad consonants, the tongue is retracted even further, almost to the point of being a [[central vowel]] (in IPA, [ïː]): ''caora'' [kïːɾˠə] 'sheep'. /uː/ is a fully back [uː] between broad consonants (e.g. ''dún'' [d̪ˠuːn̪ˠ] 'fort'), but between a broad and a slender consonant, the tongue is somewhat advanced (IPA [u̟ː]), e.g. ''triúr'' [tʲɾʲu̟ːɾˠ] 'three people', ''súil'' [sˠu̟ːlʲ] 'eye'. Between two slender consonants it is advanced even further, to a centralised vowel (IPA [üː]): ''ciúin'' [cüːnʲ] 'quiet'.
 
The near-close vowels /ɪ/ and /ʊ/ show a similar pattern. /ɪ/ is realised between slender consonants as a front [i̞], e.g. ''tigh'' [tʲi̞ɟ] 'house' (dative). After a slender consonant and before a broad one, it is a [[near-front vowel|near-front]] [ɪ] ''giota'' [ˈɟɪt̪ˠə] 'piece'. After a broad consonant and before a slender one, it is a more retracted [ɪ̈], e.g. ''tuigeann'' [ˈt̪ˠɪ̈ɟən̪ˠ] 'understands'. Finally, between two broad consonants it is a central [ɨ̞], e.g. ''goirt'' [ɡɨ̞ɾˠtʲ]<ref>Pronounced as if spelt ''guirt''.</ref> 'salty'. /ʊ/ is a [[near-back vowel|near-back]] [ʊ] when all adjacent consonants are broad, e.g. ''dubh'' [d̪ʊvˠ] 'black', and a more centralised [ʊ̟] after a slender consonant, e.g. ''giobal'' [ˈɟʊ̟bˠəɫ̪] 'rag'.
 
====Mid vowels====
The realisation of the long [[close-mid vowel]]s /eː/ and /oː/ varies according to the quality of the surrounding consonants. /eː/ is a front [eː] between two slender consonants (e.g. ''béic'' [bʲeːc] 'yell'), a centralised [ëː] between a broad and a slender consonant (e.g. ''glaoigh'' [ɡɫ̪ëːɟ] 'call'), and a more open centralised [ɛ̝̈ː] between two broad consonants (e.g. ''baol'' [bˠɛ̝̈ːɫ̪] 'danger'. /oː/ ranges from a back [oː] between two broad consonants (e.g. ''fód'' [fˠoːd̪ˠ] 'turf') to an advanced [o̟ː] between a broad and a slender consonant (e.g. ''fóid'' [fˠo̟ːdʲ] 'turf' (genitive)) to a centralised [öː] between two slender consonants (e.g. ''ceoil'' [cöːlʲ] 'music' (genitive)).
 
The short [[open-mid vowel]]s also vary depending on their environment. Short /ɛ/ ranges from a front [ɛ̝] between slender consonants (e.g. ''beidh'' [bʲɛ̝ɟ] 'will be') to a retracted [ɛ̝̈] between a broad and a slender consonant (e.g. ''bead'' [bʲɛ̝̈d̪ˠ] 'I will be', ''raibh'' [ɾˠɛ̝̈vʲ] 'was') to a central [ɘ̞] when the only adjacent consonant is broad (e.g. ''croich'' [kɾˠɘ̞] 'cross' (dative). Short /ɔ/ between two broad consonants is usually a back [ɔ̝], e.g. ''cloch'' [kɫ̪ɔ̝x] 'stone', but it is a centralised [ö] adjacent to [[nasal consonant]]s and [[labial consonant]]s, e.g. ''ansan'' [ən̪ˠˈsˠön̪ˠ] 'there', ''bog'' [bˠöɡ] 'soft'. Between a broad and a slender consonant it is a more open [ɔ̝̈]: ''scoil'' [skɔ̝̈lʲ] 'school', ''deoch'' [dʲɔ̝̈x] 'drink'.
 
Unstressed /ə/ is realised as a near-close, near-front [ɪ] when adjacent to a [[palatal consonant]], e.g. ''píce'' [ˈpʲiːcɪ] 'pike'. Next to other slender consonants, it is a mid-centralised [ɪ̽], e.g. ''sáile'' [ˈsˠaːlʲɪ̽] 'salt water'. Adjacent to broad consonants it is usually a mid central [ə], e.g. ''eolas'' [ˈoːɫ̪əsˠ] 'information', but when the preceding syllable contains one of the close back vowels /uː, ʊ/, it is realised as a mid-centralised back [ʊ̽], e.g. ''dúnadh'' [ˈd̪ˠuːn̪ˠʊ̽] 'closing', ''muca'' [ˈmˠʊkʊ̽].
 
====Open vowels====
The realisation of the [[open vowel]]s varies according to the quality of the surrounding consonants; there is also a significant difference between Munster dialects and Connacht dialects. In Munster, long /aː/ and short /a/ have approximately the same range of realisation: both vowels are relatively back in contact with broad consonants and relatively front in contact with slender consonants. Specifically, long /aː/ in word-initial position and after broad consonants is a back [ɑː], e.g. ''áit'' [ɑːtʲ] 'place', ''trá'' [t̪ˠɾˠɑː] 'beach'. Between a slender and a broad consonant, it is a retracted front [a̠ː], e.g. ''gearrfaidh'' [ˈɟa̠ːɾˠhəɟ] 'will cut', while between two slender consonants it is a fully front [aː], e.g. ''a Sheáin'' [ə çaːnʲ] 'John' (vocative). In Dingle, the back allophone is rounded to [ɒː] after broad labials, e.g. ''bán'' [bˠɒːn̪ˠ] 'white', while in [[Ring, County Waterford|Ring]], rounded [ɒː] is the usual realisation of /aː/ in all contexts except between slender consonants, where it is a centralised [ɒ̈ː] Breatnach (1947: 12–13). Short /a/ between two slender consonants is a front [a], as in ''gairid'' [ɟaɾʲədʲ]<ref>Pronounced as if spelt ''geairid''.</ref> 'short'. Between a broad and a slender consonant, it is in most cases a retracted [a̠], e.g. ''fear'' [fʲa̠ɾˠ] 'man', ''caite'' [ˈka̠tʲə] 'worn', but after broad labials and /ɫ̪/ it is a centralised front [ä], e.g. ''baile'' [bˠälʲə] 'town', ''loit'' [ɫ̪ätʲ]<ref>Pronounced as if spelt ''lait''.</ref> 'injure'. When it is adjacent only to broad consonants, it is a centralised back [ɑ̈], e.g. ''mac'' [mˠɑ̈k] 'son', ''abair'' [ɑ̈bˠəɾʲ] 'say'.
 
In Connacht varieties<ref>de Bhaldraithe (1966: 12–14); de Búrca (1958: 13–14); Mhac an Fhailigh (1968: 13–16).</ref> the allophones of short /a/ are consistently further to the front than the allophones of long /aː/. In Erris, for example, short /a/ ranges from a [[near-open front unrounded vowel|near-open front vowel]] [æ] before slender consonants (e.g. ''sail'' [sælʲ] 'earwax') to an open [a] after slender consonants (e.g. ''geal'' [ɟaɫ] 'bright) to a centralised back [ɑ̈] between broad consonants (e.g. ''capall'' [ˈkɑ̈pəɫ̪] 'horse'). Long /aː/, on the other hand, ranges from a back [ɑː] between broad consonants (e.g. ''bád'' [bˠɑːd̪ˠ] 'boat') to an advanced back [ɑ̟ː] before slender consonants (e.g. ''fáil'' [fˠɑ̟ːlʲ] 'to get') to a centralised back [ɑ̈ː] after slender consonants (e.g. ''breá'' [bʲɾʲɑ̈ː] 'fine'). In [[Tourmakeady]],<ref>de Búrca (1958: 13).</ref> the back allophone is rounded to [ɒː] after broad labials, e.g. ''bán'' [bˠɒːn̪ˠ] 'white'. In Connemara, the allophones of /a/ are lengthened in duration, so that only vowel quality distinguishes the allophones of /a/ from those of /aː/.<ref>de Bhaldraithe (1966: 12–13).</ref>
 
====Diphthongs====
The starting point of /əi/ ranges from a near-open central [ɐ] after broad consonants to an open-mid centralised front [ɛ̈] after slender consonants, and its end point ranges from a near-close near-front [ɪ] before slender consonants to a centralised [ɪ̈] before broad consonants.<ref>Breatnach (1947: 23–24).</ref> Examples include ''cladhaire'' [kɫ̪ɐɪɾʲə] 'rogue', ''gadhar'' [gɐɪ̈ɾˠ] 'dog', ''cill'' [cɛ̈ɪlʲ] 'church', and ''leigheas'' [lʲɛ̈ɪ̈sˠ] 'cure'.
 
The starting point of /əu/ ranges from a near-open central [ɐ] after broad consonants to an open-mid advanced central [ɜ̟] after slender consonants, and its end point ranges from a near-close near-back [ʊ] before broad consonants to a centralised [ʊ̈] before slender consonants.<ref>Breatnach (1947: 24–25).</ref> Examples: ''bodhar'' [bˠɐʊɾˠ] 'deaf', ''feabhas'' [fʲɜ̟ʊsˠ] 'improvement', ''labhairt'' [ɫ̪ɐʊ̈ɾʲtʲ] 'speak', ''meabhair'' [mʲɜ̟ʊ̈ɾʲ] 'memory'. In West Muskerry and the Dingle Peninsula, however, the starting point of /əu/ is rounded and further back after broad consonants, e.g. ''gabhar'' [gɔʊɾˠ] 'goat'.<ref>Ó Cuív (1944: 29); Ó Sé (2000: 24).</ref>
 
The starting point of /iə/ ranges from a close front [i] after slender consonants to a retracted [i̠] after word-initial broad /ɾˠ/ (the only context in which it appears after a broad consonant). Its end point ranges from a mid central [ə] before broad consonants to a close-mid centralised front [ë] before slender consonants.<ref>Ó Sé (2000: 24).</ref> Examples: ''ciall'' [ciəɫ̪] 'sense', ''riamh'' [ɾˠi̠əvˠ] 'ever', ''diabhail'' [dʲiëlʲ] 'devils'.
 
The starting point of /uə/ is consistently a close back [u] while the end point ranges from [ɐ] to [ɪ̽]:<ref>Ó Sé (2000: 25).</ref>: ''thuas'' [huɐsˠ] 'above', ''uan'' [uən̪ˠ] 'lamb', ''buail'' [bˠuɪ̽lʲ] 'strike'.
 
===Nasalised vowels===
In general, vowels in Irish are [[nasalization|nasalised]] when adjacent to [[nasal consonant]]s. For some speakers, there are reported to be [[minimal pair]]s between [[nasal vowel]]s and oral vowels, indicating that nasal vowels are also separate phonemes. However, the contrast is not robust in any dialect; most published descriptions say that contrastively nasal vowels are present in the speech of only some (usually older) speakers. Potential minimal pairs include those shown in the table below.<ref>Quiggin (1906: 65); Sjoestedt (1931: 68); Ó Cuív (1944: 54); Ó Sé (2000: 25).</ref>

In addition, where a vowel is nasalised because it is adjacent to a nasal consonant, it often retains its nasalisation in related forms where the consonant is no longer nasal. For example, the nasal /m/ of ''máthair'' [ˈmãːhəɾʲ] 'mother' is replaced by non-nasal /w/ in the phrase ''a mháthair'' [ə ˈwãːhəɾʲ] 'his mother', but the vowel remains nasalised.<ref>Quiggin (1906: 65).</ref> Similarly, in ''sneachta'' [ˈʃnʲãxt̪ˠə] 'snow' the vowel after the /nʲ/ is nasalised, while in ''an tsneachta'' [ə ˈtʲɾʲãxt̪ˠə] 'the snow' (genitive), the /nʲ/ is replaced by /ɾʲ/ in some dialects, but the nasalised vowel remains.<ref>de Bhaldraithe (1966: 46).</ref>
 
==Phonotactics==
The most interesting aspects of Irish [[phonotactics]] revolve around the behaviour of [[consonant cluster]]s. Here it is important to distinguish between clusters that occur at the beginnings of words and those that occur after vowels, although there is overlap between the two groups.
 
===Word-initial consonant clusters===
Irish words can begin with clusters of two or three consonants. In general, all the consonants in a cluster agree in their quality, i.e. all are either broad or slender. Two-consonant clusters consist of an [[obstruent consonant]] followed by a [[liquid consonant|liquid]] or [[nasal consonant]] (however, labial obstruents may not be followed by a nasal); examples include ''bleán'' /bʲlʲaːn/ 'milking', ''breá'' /bʲɾʲaː/ 'fine', ''cnaipe'' /ˈkn̪ˠapʲə/ 'button', ''dlí'' /dʲlʲiː/ 'law', ''gnáth'' /ɡn̪ˠaː/ 'usual', ''pleidhce'' /ˈpʲlʲəicə/ 'idiot', ''slios'' /ʃlʲɪsˠ/ 'slice', ''sneachta'' /ˈʃnʲaxt̪ˠə/ 'snow', ''tlúth'' /t̪ˠɫ̪uː/ 'poker', and ''tnúth'' /t̪ˠn̪ˠuː/ 'long for'.<ref>Ní Chiosáin (1999).</ref> In addition, /sˠ/ and /ʃ/ may be followed by a voiceless stop, as in ''sparán'' /ˈsˠpˠaɾˠaːn̪ˠ/ 'purse' and ''scéal'' /ʃceːɫ̪/ 'story'. Further, the cluster /mˠn̪ˠ/ occurs in the word ''mná'' /mˠn̪ˠaː/ 'women' and a few forms related to it. Three-consonant clusters consist of /sˠ/ or /ʃ/ plus a voiceless stop plus a liquid. Examples include ''scliúchas'' /ˈʃclʲuːxəsˠ/ 'rumpus', ''scread'' /ʃcɾʲad̪ˠ/ 'scream', ''splanc'' /sˠpˠɫ̪aŋk/ 'flash', ''spraoi'' /sˠpˠɾˠiː/ 'fun', and ''stríoc'' /ʃtʲɾʲiːk/ 'streak'.
 
One exception to quality agreement is that broad /sˠ/ is found before slender labials (and for some speakers in Connemara and Dingle before /c/ as well).<ref>de Bhaldraithe (1966: 106); Ó Sé (2000: 31).</ref> Examples include: ''sméara'' /sˠmʲeːɾˠə/ 'berries', ''speal'' /sˠpʲal/ 'scythe', ''spleách'' /sˠpʲlʲaːx/ 'dependent', ''spreag'' /sˠpʲɾʲaɡ/ 'inspire', ''scéal'' /ʃceːɫ̪/ ~ /sˠceːɫ̪/ 'story'.
 
In the environment of an initial [[consonant mutation]], there is a much wider range of possible onset clusters;<ref>Ní Chiosáin (1999); Ó Sé (2000: 33).</ref> for example, in a ''lenition'' environment the following occur: ''bhlas'' /wɫ̪asˠ/ 'tasted', ''bhris'' /vʲɾʲɪʃ/ 'broke', ''chleacht'' /çlʲaxt̪ˠ/ 'practiced', ''chrom'' /xɾˠɔmˠ/ 'bent', ''ghreamaigh'' /ˈjɾʲamˠə/ 'stuck', ''ghníomhaigh'' /ˈjnʲiːwə/ 'acted', ''shleamhnaigh'' /hlʲəun̪ˠə/ 'slipped', ''shnámh'' /hn̪ˠaːw/ 'swam', ''shroich'' /hɾˠɪç/ 'reached'. In an ''eclipsis'' environment the following are found: ''mbláth'' /mˠɫ̪aː/ 'flower', ''mbliana'' /ˈmʲlʲiən̪ˠə/ 'years', ''mbrisfeá'' /ˈmʲɾʲɪʃhaː/ 'you would break', ''ndlúth'' /n̪ˠɫ̪uː/ 'warp', ''ndroichead'' /ˈn̪ˠɾˠɔhəd̪ˠ/ 'bridge', ''ndréimire'' /ˈnʲɾʲeːmʲəɾʲə/ 'ladder', ''ngléasfá'' /ˈɲlʲeːsˠhaː/ 'you would dress', ''ngreadfá'' /ˈɲɾʲadhaː/ 'you would leave', ''ngníomhófá'' /ˈɲnʲiːwoːhaː/ 'you would act'.
 
In Donegal, Mayo, and Connemara dialects (but not usually on the Aran Islands), the coronal nasals /nˠ, nʲ/ can follow only /sˠ, ʃ/ respectively in a word-initial cluster. After other consonants, they are replaced by /ɾˠ, ɾʲ/ (Ó Siadhail|Wigger (1975: 116–17), Ó Siadhail (1989: 95)): ''cnoc'' /kɾˠʊk/ 'hill', ''mná'' /mˠɾˠaː/ 'women', ''gnaoi'' /ɡɾˠiː/ 'liking', ''tnúth'' /t̪ˠɾˠuː/ 'long for'.
 
Under lenition, /sˠn̪ˠ, ʃnʲ/ become /hn̪ˠ, hnʲ/ as expected in these dialects, but [[Irish initial mutations#After proclitics|after the definite article ''an'']] they become /t̪ˠɾˠ, tʲɾʲ/: ''sneachta'' /ʃnʲaxt̪ˠə/ 'snow', ''shneachta'' /hnʲaxt̪ˠə/ 'snow' (lenited form), ''an tsneachta'' /ə tʲɾʲaxt̪ˠə/ 'the snow' (genitive).
 
===Post-vocalic consonant clusters and epenthesis===
Like word-initial consonant clusters, post-vocalic consonant clusters usually agree in broad or slender quality. The only exception here is that broad /ɾˠ/, not slender /ɾʲ/, appears before the slender coronals /tʲ, dʲ, ʃ, nʲ, lʲ/ Ó Sé (2000: 34–36): ''beirt'' /bʲɛɾˠtʲ/ 'two people', ''ceird'' /ceːɾˠdʲ/ 'trade', ''doirse'' /ˈd̪ˠoːɾˠʃə/ 'doors', ''doirnín'' /d̪ˠuːɾˠˈnʲiːnʲ/ 'handle', ''comhairle'' /ˈkuːɾˠlʲə/ 'advice'.
 
A cluster of /ɾˠ, ɾʲ/, /ɫ̪, lʲ/, or /n̪ˠ, nʲ/ followed by a labial or dorsal consonant (except the voiceless stops /pˠ, pʲ/, /k, c/) is broken up by an [[epenthesis|epenthetic]] vowel /ə/: ''borb'' /ˈbˠɔɾˠəbˠ/ 'abrupt', ''gorm'' /ˈɡɔɾˠəmˠ/ 'blue', ''dearmad'' /ˈdʲaɾˠəmˠəd̪ˠ/ 'mistake', ''dearfa'' /ˈdʲaɾˠəfˠə/ 'certain', ''seirbhís'' /ˈʃɛɾʲəvʲiːʃ/ 'service', ''fearg'' /ˈfʲaɾˠəɡ/ 'anger', ''dorcha'' /ˈd̪ˠɔɾˠəxə/ 'dark', ''dalba'' /ˈd̪ˠaɫ̪əbˠə/ 'bold', ''colm'' /ˈkɔɫ̪əmˠ/ 'dove', ''soilbhir'' /ˈsˠɪlʲəvʲəɾʲ/ 'pleasant', ''gealbhan'' /ˈɟaɫ̪əwən̪ˠ/ 'sparrow', ''binb'' /ˈbʲɪnʲəbʲ/ 'venom', ''Banba'', /ˈbˠan̪ˠəbə/ (a name for Ireland), ''ainm'' /ˈanʲəmʲ/ 'name', ''meanma'' /ˈmʲan̪ˠəmˠə/ 'mind', ''ainmhí'' /ˈanʲəvʲiː/ 'animal'.<ref>Ní Chiosáin (1999).</ref>
 
There is no epenthesis, however, if the vowel preceding the cluster is long or a diphthong: ''fáirbre'' /ˈfˠaːɾʲbʲɾʲə/ 'wrinkle', ''téarma'' /ˈtʲeːɾˠmˠə/ 'term', ''léargas'' /ˈlʲeːɾˠɡəsˠ/ 'insight', ''dualgas'' /ˈd̪ˠuəɫ̪ɡəsˠ/ 'duty'. There is also no epenthesis into words that are at least three syllables long: ''firmimint'' /ˈfʲɪɾʲmʲəmʲənʲtʲ/ 'firmament', ''smiolgadán'' /ˈsˠmʲɔɫ̪ɡəd̪ˠaːn̪ˠ/ 'throat', ''caisearbhán'' /ˈkaʃəɾˠwaːn̪ˠ/ 'dandelion', ''Cairmilíteach'' /ˈkaɾʲmʲəlʲiːtʲəx/ 'Carmelite'.
 
==Phonological processes==
===Vowel-initial words===
Vowel-initial words in Irish exhibit behaviour that has led linguists to suggest that the vowel sound they begin with on the surface is not, at a more abstract level, actually the first sound in the word. Specifically, when a ''[[clitic]]'' ending in a consonant precedes a word beginning with the vowel, the consonant of the clitic surfaces as either broad or slender, depending on the specific word in question. For example, the ''n'' of the [[definite article]] ''an'' 'the' is slender before the word ''iontais'' 'wonder' but broad before the word ''aois'' 'age': ''an iontais'' /ənʲ&nbsp;ˈiːn̪ˠt̪ˠəʃ/ 'the wonder' (genitive) vs. ''an aois'' /ən̪ˠ&nbsp;ˈiːʃ/ 'the age'.<ref>Ní Chiosáin (1991: 80–82).</ref>
 
One analysis of these facts<ref>Ní Chiosáin (1991: 83).</ref> is that vowel-initial words actually begin, at an abstract level of representation, with a kind of ''empty'' consonant that consists of nothing except the information 'broad' or 'slender'. Another analysis is that vowel-initial words, again at an abstract level, all begin with one of two [[semivowel]]s, one triggering palatalisation and the other triggering velarisation of a preceding consonant.<ref>Ó Siadhail & Wigger (1975: 98–99); Ó Siadhail (1989: 64–65).</ref>
 
===Lengthening before fortis sonorants===
Where reflexes of the Old Irish [[#Fortis and lenis sonorants|fortis sonorants]] appear in syllable-final position (in some cases, only in word-final position), they trigger a lengthening or ''diphthongisation'' of the preceding vowel in most dialects of Irish.<ref>O'Rahilly (1932: 49–52); Ó Siadhail & Wigger (1975: 89–94); Ó Siadhail (1989: 49–50); Carnie (2002).</ref> The details vary from dialect to dialect.
 
In Donegal and Mayo, lengthening is found only before ''rd, rl, rn'', before ''rr'' (except when a vowel follows), and in a few words also before word-final ''ll''.<ref>de Búrca (1958: 132–34); Mhac an Fhailigh (1968: 163–64); Evans (1969: 127); Ó Baoill (1996: 16).</ref> For example: ''barr'' /bˠaːɾˠ/ 'top', ''ard'' /aːɾˠd̪ˠ/ 'tall', ''orlach'' /ˈoːɾˠɫ̪ax/ 'inch', ''tuirne'' /ˈt̪uːɾˠn̠ʲə/ 'spinning wheel', ''thall'' /haːɫ̪/ 'yonder'.
 
In Connemara,<ref>de Bhaldraithe (1966: 109–12).</ref> the Aran Islands,<ref>Finck (1899).</ref> and Munster,<ref>Breatnach (1947: 142–44); Ó Cuív (1944: 121–23).</ref> lengthening is generally found not only in the environments listed above, but also before ''nn'' (unless a vowel follows) and before ''m'' and ''ng'' at the end of a word. For example, the word ''poll'' 'hole' is pronounced /pˠəuɫ̪/ in all of these regions, while ''greim'' 'grip' is pronounced /ɟɾʲiːmʲ/ in Connemara and Aran and /ɟɾʲəimʲ/ in Munster.
 
Because in many cases vowels behave differently before broad sonorants than before slender ones, and because there is generally no lengthening (except by ''analogy'') when the sonorants are followed by a vowel, there is a variety of vowel [[alternation (linguistics)|alternation]]s between different related word forms. For example, in Dingle ''ceann'' 'head' is pronounced /cəun̪ˠ/ with a diphthong, but ''cinn'' (the [[genitive]] singular of the same word) is pronounced /ciːnʲ/ with a long vowel, while ''ceanna'' (the plural, meaning 'heads') is pronounced /ˈcan̪ə/ with a short vowel.<ref>Ó Sé (2000: 40–42).</ref>
 
This lengthening has received a number of different explanations within the context of theoretical phonology. All accounts agree that some property of the fortis sonorant is being transferred to the preceding vowel, but the details about what property that is vary from researcher to researcher. One argument is that the fortis sonorant is ''[[tenseness|tense]]'' (a term only vaguely defined in phonetics) and that this tenseness is transferred to the vowel, where it is realised phonetically as vowel length and/or diphthongisation.<ref>Ó Siadhail & Wigger (1975: 89–90). Repeated in Ó Siadhail (1989: 48–50).</ref> Another argument holds that the triggering consonant is underlying associated with a unit of 'syllable weight' called a [[mora (linguistics)|''mora'']]; this mora then shifts to the vowel, creating a long vowel or a diphthong.<ref>Ní Chiosáin (1991: 188–95).</ref> Based on this,  the fortis sonorants could have an [[advanced tongue root]] (that is, the bottom of the tongue is pushed upward during articulation of the consonant) and that diphthongisation is an [[articulatory phonetics|articulatory]] effect of this tongue movement.<ref>Carnie (2002).</ref>
 
===Devoicing===
Where a voiced [[obstruent]] or /w/ comes into contact with /h/, the /h/ is absorbed into the other sound, which then becomes voiceless (in the case of /w/, devoicing is to /fˠ/). Devoicing is found most prominently in the [[future tense|future]] of [[Irish verbs#First conjugation|first conjugation]] verbs (where the /h/ sound is represented by the letter ''f'') and in the formation of [[verbal adjective]]s (where the sound is spelt ''th''). For example, the verb ''scuab'' /sˠkuəbˠ/ 'sweep' ends in the voiced consonant /bˠ/, but its future tense ''scuabfaidh'' /ˈsˠkuəpˠəɟ/ 'will sweep' and verbal adjective ''scuabtha'' /ˈsˠkuəpˠə/ 'swept' have the voiceless consonant /pˠ/.<ref>Breatnach (1947: 137–38).</ref>
 
===Sandhi===
Irish exhibits a number of external [[sandhi]] effects, i.e. phonological changes across word boundaries, particularly in rapid speech. The most common type of sandhi in Irish is [[assimilation]], which means that a sound changes its pronunciation in order to become more similar to an adjacent sound.
 
One type of assimilation in Irish is found when a coronal consonant (one of ''d, l, n, r, s, t'') changes from being broad to being slender before a word that begins with a slender coronal consonant, or from being slender to being broad before a word that begins with a broad coronal consonant. For example, ''feall'' /fʲaɫ̪/ 'deceive' ends with a broad ''ll'', but in the phrase ''d'fheall sé orm'' [dʲal̠ʲ ʃə ɔɾˠəmˠ] 'it deceived me' the ''ll'' has become slender because the following word, ''sé'', starts with a slender coronal consonant.<ref> Quiggin (1906: 146–50).</ref>
 
The consonant ''n'' may also assimilate to the [[place of articulation]] of a following consonant, becoming labial before a labial consonant, palatal before a palatal consonant, and velar before a velar consonant.<ref>de Búrca (1958: 65–68).</ref> For example, the ''nn'' of ''ceann'' /can̪ˠ/ 'one' becomes [mˠ]) in ''ceann bacach'' [camˠ ˈbˠakəx]) 'a lame one' and [ŋ]) in ''ceann carrach'' [caŋ ˈkaɾˠəx]) 'a scabbed one'.
 
Finally, a voiced consonant at the end of a word may become voiceless when the next word begins with a voiceless consonant,<ref>Finck (1899: 123–124).</ref> as in ''lúb sé'' [ɫ̪uːpˠ ʃeː]) 'he bent', where the ''b'' sound of ''lúb'' /ɫ̪uːbˠ/ 'bent' has become a ''p'' sound before the voiceless ''s'' of ''sé''.
 
==Stress==
===General facts of stress placement===
An Irish word normally has only one [[stress (linguistics)|stress]]ed syllable, namely the first syllable of the word.<ref>In IPA transcription, a stressed syllable is marked with the symbol [ ˈ ]) to the left of the syllable.</ref> Examples include ''d'imigh'' [ˈdʲɪmʲiː] 'left' (past tense of ''leave'') and ''easonóir'' [ˈasˠən̪ˠoːɾʲ] 'dishonour'
de Búrca (1958: 74–75). However, certain words, especially [[adverb]]s and [[loanword]]s, have stress on a noninitial syllable, e.g. ''amháin'' [əˈwaːnʲ] 'only', ''tobac'' [təˈbak] 'tobacco'.
 
In most [[compound (linguistics)|compound]] words, primary stress falls on the first member and a [[secondary stress]] (marked with [ ˌ ])) falls on the second member, e.g. ''lagphórtach'' [ˈɫ̪agˌfˠɔɾˠt̪ˠəx] 'spent bog'. Some compounds, however, have primary stress on both the first and the second member, e.g. ''deargbhréag'' [ˈdʲaɾˠəgˈvʲɾʲeːg] 'a terrible lie'.
 
In Munster, stress is attracted to a long vowel or diphthong in the second or third syllable of a word, e.g. ''cailín'' [kaˈlʲiːnʲ] 'girl', ''achainí'' [axəˈnʲiː] 'request'.<ref>Ó Sé (2000: 46–47).</ref>
 
In the now extinct accent of East Mayo, stress was attracted to a long vowel or diphthong in the same way as in Munster; in addition, stress was attracted to a short vowel before word-final ''ll'', ''m'', or ''nn'' when that word was also final in its utterance.<ref>Lavin (1957); Dillon (1973); Green (1997: 86–90).</ref> For example, ''capall'' 'horse' was pronounced [kaˈpˠɞɫ̪] in isolation or as the last word of a sentence, but as [ˈkapˠəɫ̪] in the middle of a sentence.
 
===The nature of unstressed vowels===
In general, short vowels are all reduced to [[schwa]] ([ə]) in unstressed syllables, but there are some exceptions. In Munster, if the third syllable of a word is stressed and the preceding two syllables are short, the first of the two unstressed syllables is ''not'' reduced to schwa; instead it receives a secondary stress, e.g. ''spealadóir'' [ˌsˠpʲaɫ̪əˈd̪ˠoːɾʲ] 'scythe-man'.<ref>Ó Cuív (1944: 67).</ref> Also in Munster, an unstressed short vowel is not reduced to schwa if the following syllable contains a stressed [iː] or [uː], e.g. ''ealaí'' [aˈɫ̪iː] 'art', ''bailiú'' [bˠaˈlʲuː] 'gather'.<ref>Ó Cuív (1944: 105).</ref> In Ulster, long vowels in unstressed syllables are shortened but are not reduced to schwa, e.g. ''cailín'' [ˈkalʲinʲ] 'girl', ''galún'' [ˈgaɫunˠ] 'gallon'.<ref>Ó Dochartaigh (1987: 19 ff.); Hughes (1994: 626–27).</ref>
 
==Processes relating to /x/==
The [[voiceless velar fricative]] /x/, spelt ''ch'', is associated with some unusual patterns in many dialects of Irish. For one thing, its presence after the vowel /a/ triggers behavior atypical of short vowels; for another, /x/ and its slender counterpart /ç/ interchange with the [[voiceless glottal fricative]] /h/ in a variety of ways, and can sometimes be deleted altogether.
 
===Behaviour of /ax/===
In Munster, stress is attracted to /a/ in the second syllable of a word if it is followed by /x/, ''provided'' the first syllable (and third syllable, if there is one) contains a short vowel.<ref>Ó Cuív (1944: 66).</ref> Examples include ''bacach'' [bˠəˈkax] 'lame' and ''slisneacha'' [ʃlʲəˈʃnʲaxə] 'chips'. However, if the first or third syllable contains a long vowel or diphthong, stress is attracted to that syllable instead, and the /a/ before /x/ is reduced to [ə] as normal, e.g. ''éisteacht'' [ˈeːʃtʲəxt̪ˠ] 'listen', ''moltachán'' [ˌmˠɔɫ̪həˈxaːn̪ˠ].<ref>Pronounced as if spelt ''molthachán''.</ref> 'wether'.<ref>Ó Cuív (1944: 66).</ref> In Ulster, unstressed [a] before [x] is not reduced to [[schwa]], e.g. ''eallach'' [ˈaɫ̪ax] 'cattle'.<ref>Quiggin (1906: 9).</ref>
 
===Interaction of /x/ and /ç/ with /h/===
In many dialects of Irish, the voiceless dorsal fricatives /x/ and /ç/ alternate with /h/ under a variety of circumstances. For example, /h/ is replaced by /ç/ before back vowels, e.g. ''thabharfainn'' /ˈçuːɾˠhən̠ʲ/<ref>Pronounced as if spelt ''thiúrfainn''.</ref> 'I would give', ''sheoil'' /çoːlʲ/ 'drove'.<ref>de Búrca (1958: 129–30).</ref> In Munster, /ç/ becomes /h/ after a vowel, e.g. ''fiche'' /fʲɪhə/ 'twenty'.<ref>Ó Cuív (1944: 117–18).</ref> In Ring, /h/ becomes /x/ at the end of a monosyllabic word, e.g. ''scáth'' /sˠkaːx/ 'fear'.<ref>Breatnach (1947: 137).</ref> In some Ulster dialects, such as that of [[Tory Island]], /x/ can be replaced by /h/, e.g. ''cha'' /ha/ 'not', and can even be deleted word-finally, as in ''santach'' /ˈsˠan̪ˠt̪ˠah ~ ˈsˠan̪ˠt̪ˠa/ 'greedy'.<ref>Hamilton (1974: 152).</ref> In other Ulster dialects, /x/ can be deleted before /t̪ˠ/ as well, e.g. ''seacht'' [ʃat̪ˠ] 'seven'.<ref>Ó Searcaigh (1925: 136).</ref>

==Comparison with other languages==
===Scottish Gaelic and Manx===
Many of the phonological processes found in Irish are also found in its nearest relatives, [[Scottish Gaelic language|Scottish Gaelic]] and [[Manx language|Manx]]. For example, both languages contrast 'broad' and 'slender' consonants, but only at the coronal and dorsal [[place of articulation|places of articulation]]; both Scottish Gaelic and Manx have lost the distinction in labial consonants. The change of /kn̪ˠ gn̪ˠ mn̪ˠ/ etc. to /kɾˠ gɾˠ mɾˠ/ etc. is found in Manx and in most Scottish Gaelic dialects. Evidence from written manuscripts suggests it had begun in Scottish Gaelic as early as the [[sixteenth century]] and was well established in both Scottish Gaelic and Manx by the late [[seventeenth century|seventeenth]] to early [[eighteenth century]]. Lengthening or diphthongisation of vowels before fortis sonorants is also found in both languages.<ref>O'Rahilly (1932: 22-23; 49–52).</ref> The stress pattern of Scottish Gaelic is the same as that in Connacht and Ulster Irish, while in Manx, stress is attracted to long vowels and diphthongs in non-initial syllables, but under more restricted conditions than in Munster.<ref>O'Rahilly (1932: 113–115); Green (1997: 90–93).</ref> Manx and many dialects of Scottish Gaelic also share with Ulster Irish the property of not reducing unstressed /a/ to [ə] before /x/.<ref>O'Rahilly (1932: 110–12).</ref>
 
===Hiberno-English===
Irish phonology has had a significant influence on the phonology of [[Hiberno-English]].<ref>Wells (1982: 417–50).</ref> For example, most of the vowels of Hiberno-English (with the exception of /ɔɪ/) correspond to vowel [[phone]]s (which may or may not be phonemes) of Irish. The Irish stops /t̪ˠ/ and /d̪ˠ/ have been taken over (though without distinctive velarisation) into Hiberno-English as common realisations of the English phonemes /θ/ and /ð/. Hiberno-English also allows /h/ to appear in positions where it is permitted in Irish but excluded in other [[English dialects]], such as before an unstressed vowel (e.g. ''Haughey'' ˈ[hɒhi]) and at the end of a word (e.g. ''McGrath'' [məˈgɹæh]). Another feature of Hiberno-English phonology probably taken over from Irish is epenthesis in words like ''film'' [ˈfɪləm] and ''form'' [ˈfɔɹəm].

Phonology here refers to the sound patterns of the Irish language, which vary by dialect but share certain features. Phonologists have traditionally classified most of the language's 33 or so consonants into 'broad' and 'slender' pairs, i.e. respectively velarised or palatalised, involving different placement of the tongue. This difference is phonemic: substituting one for another produces a different word, e.g. 'cow' and beo 'alive'. Such consonants also affect which of Irish's 15 or so vowels may acceptably co-occur with them.

Another interesting feature of Irish phonology concerns consonant clusters, i.e. sequences of consonants. Words may begin with two or three consonants, which usually agree in being broad or slender. Two-member clusters consist of an obstruent consonant followed by a liquid (e.g. pleidhce /ˈpʲlʲəicə/ 'idiot') or nasal consonant (e.g. cnaipe /ˈkn̪ˠapʲə/ 'button'); three-member clusters start with a sibilant as in sparán /ˈsˠpˠaɾˠaːn̪ˠ/ 'purse', preceding a voiceless stop and a liquid.[1] However, under consonant mutation (changing consonants according to some rule), other sequences can occur: e.g. bhlas [wɫ̪asˠ] 'tasted', mbláth [mˠɫ̪aː] 'flower'.[2]

Stress

Stress is generally predictable in Irish: it is placed on the first syllable of the word, e.g. easonóir [ˈasˠən̪ˠoːɾʲ] 'dishonour'.[4] Exceptions are often adverbs or loanwords, such as amháin [əˈwaːnʲ] 'only' and tobac [təˈbak] 'tobacco'. In compund words, such as lagphórtach [ˈɫ̪agˌfˠɔɾˠt̪ˠəx] 'spent bog', primary stress falls on the first member. When a short vowel is unstressed, it generally surfaces as the schwa [ə], similar to the vowels beginning and ending the English word aroma.
