Silent and invisible letters in English

Silent letters

Silent letters constitute a notorious phenomenon in English: in wréstle, for example, only four out of the seven letters are actually sounded (*résl), and there can be strings of them in place names, exemplified by the trio Léicester, Glóucester and Worcester, pronounced Léster, *Glóster and *Wùster. (The accents show stress and pronunciation, see English spellings; there is also a key at the foot of this page; * is placed before an incorrect spelling.)

Silent letters can be misleading, as in Thaîland and îsland, which rhyme, or they can be easy to ignore ("redundant"), as in wróng, yeôman, and lôw.

They can serve to distinguish between words that sound the same:

knôw knowledge = nô negative

knót tie = nót negative

wráp parcel = ráp knock, talk

wrîte read = rîght correct = rîte ritual

chéck verify = BrE chéque money

Some typical examples

• b finally after m or before final t (-mb -bt)
• g or k initially before n (gn-, kn-)
• gh finally or before final t (-gh -ght)
• l after à and before final f or m (-lf -lm)
• n finally after m (-mn).

Invisible letters

A somewhat rarer phenomenon in English is the invisible letter, the opposite of a silent one, a letter which is pronounced but not written.

• There is an invisible initial w in òne, which has the same pronunciation as the past tense of the verb to wín: òne 1 = wòn win.
• In some American writing, in what in British English would be a sounded apostrophe plus s, the s is omitted in writing but still sounded: BrE Jônes's cát = AmE Jônes' cát; this should not be confused with the plural possessive s' as in thêse càrs' lîghts (cf. thís càr's lîghts), sòme còuntries' lêaders, which is common to British and American, and which does not have an extra s sound. (The written habit has led to a tendency to follow suit in speech, e.g. in the song "Béttê Dâvis' Eŷes", which is sung as Dâvis, not Dâvis's.)
• In British English and Commonwealth English, there is a frequently sounded r between two words, the first of which ends in a vowel sound, and the second of which begins with one. In Mr Zénda ís hêre to sêe yoû, many speakers will pronounce an unwritten r between the final a of Zénda and the following word ís, as if Zénda were spelt "Zender" (which in a non-rhotic variant such as BrE would sound the same). Unlike the first example, this is not a compulsory usage, and the invisible r may be replaced by a glottal stop, or the first word may glide into the second with no r sound—in rapid, informal speech, of course, one would say: Mr Zénda's...
• The Scottish word búrgh can be pronounced as the equivalent bòrough is in England, *búrə.
• There is an invisible á following the M in names like McEnroe and McIlroy, which both begin Máck-: in some versions, and in other such names, the á is of course visible: MácKintosh person = máckintosh raincoat, as it is in Mackénzie, MacKénzie; and it really is unnecessary in the likes of McCǒrmack *Məcǒrməck.
• A variant pronunciation of St Jóhn *Səntjón is *Sínjən, with an invisible í.
• In slow speech, in Northámpton and Southámpton, and in Lêithead, an aspirate h may be heard in addition to the h of th. Similarly, thréshold can sound like either "thrésh ôld" or "thrésh hôld", cf. lêasehôld.
• A comparatively common type is where English speakers attempt to pronounce foreign names with unfamiliar consonant clusters, and insert extra vowels to make it easier: e.g. Khmér, where the h represents an aspirate between two other consonants, is often pronounced *Kəmãir. This is a very old phenomenon, as witness the transformation of the Viking Knût into Canûte.
• From Russian and related languages, names that have the letter Е, е, which sounds roughly like 'yé', often omit the consonantal 'y' from the transliteration: Evgény = Yevgény—which, strictly speaking, has a second invisible 'y': *Yevgyény (Евгений).

Letter inversion

A related phenomenon is pronunciation of letters in a different order from the written one.

• In Scotland, North America, etc., wh is pronounced "hw" (this phoneme has also been analysed as an unvoiced w).
• Many speakers pronounce nûclêar as *nûcular (though this is regarded as incorrect).
• In some proper names, the ending -thŏrp(e) is pronounced -thrəp or -trəp (in spelling too, alongside the names Thŏrp(e) and Thrúpp, the endings -throp and -thrup are also found).

Notes

• The accents show stress and pronunciation (see English spellings): A: sát, mâde, pàrk, cāst (cást/càst), åll, ãir; E: ére, êar, vèin, fërn; I: sít, mîne, skì, bïrd; O: sóng, môde, lòve, wörd, ŏr; OO: moôn, foòt; U: sún, mûse, fùll, pürr; W: neŵ, ẁant; Y: gým, mŷ, keỳ, mÿrrh.
