| ===Properties of natural languages===
| |
| Linguistic scholars have described human languages as a system of symbols (sometimes known as [[lexeme]]s) and the [[grammar]] ([[wiktionary:rule|rule]]s) by which the symbols are manipulated. The assignment of meaning to a symbol in a human language is arbitrary. Any symbol can be mapped onto any concept (or even onto one of the rules of the grammar). For instance, there is nothing about the [[Spanish language|Spanish]] word ''{{lang|es|nada}}'' itself that forces Spanish speakers to use it to mean "nothing". That is the meaning all Spanish speakers have memorized for that sound pattern. But for [[Croatian language|Croatian]] speakers ''{{lang|hr|nada}}'' means "hope". Not all mappings of symbols to concepts are entirely arbitrary, however; spoken language may assign meaning to symbols because the spoken sound is imitative of a natural phenomenon. Thus for example, the word "meow" sounds similar to what it represents (see [[Onomatopoeia]])<ref name="onomatopoeia">{{cite web|url=http://www.georgetown.edu/faculty/ballc/animals/animals.html|title=Sounds of the World's Animals|publisher=Catherine N. Ball, Adjunct Associate Professor, Department of Linguistics, Georgetown University|year=year not specified|accessdate=2007-04-12}}</ref>.

| ===Origins of human language===
| |
| No one yet agrees on when language was first used by humans (or their ancestors). Estimates range from about two million (2,000,000) years ago, during the time of ''[[Homo habilis]]'', to as recently as forty thousand (40,000) years ago, during the time of [[Cro-Magnon]] man.

| ===Language versus dialect classification===
| |
| From the point of view of [[Historical_linguistics|historical]] [[Comparative_linguistics|comparative]] [[Linguistics|linguistics]], two [[natural language]]s with noticable difference in pronunciation but which are still [[mutual intelligibility|mutually intelligible]] may be classified as being two ''[[dialect|dialects]]'' of the same language. However, the decision to term a particular regional language as its own language, versus a ''dialect'' of another language, is sometimes also the result of political divisions, cultural differences, distinctive [[writing systems]], or other factors. [[Max Weinreich]] is credited as saying that "[[Language-dialect aphorism|a language is a dialect with an army and a navy]]". For instance, some [[dialect]]s of [[German language|German]] are [[mutually intelligible]] with some dialects of [[Dutch language|Dutch]]. The transition between languages within the same [[language family]] is usually gradual (see [[dialect continuum]]). The concepts of [[Ausbausprache - Abstandsprache - Dachsprache|Ausbausprache, Abstandsprache and Dachsprache]] are used to make finer [[distinction]]s about the degrees of difference between languages or dialects.
| |
|
| |
| ===Study of grammar===
| |
| The oldest surviving written grammar for any language is believed to be the ''[[Tolkāppiyam]]'' (தொல்காப்பியம்), a book on the grammar of the [[Tamil language]], written around [[200 BC]] by Tolkāppiyar. Its classification of the alphabet into [[consonant]]s and [[vowel]] was a breakthrough. The historical record of the study of language begins in [[North India]] with [[Pāṇini]], the [[5th century BC]] grammarian who formulated 3,959 rules of [[Sanskrit language|Sanskrit]] [[morphology (linguistics)|morphology]], known as the ''{{Unicode|[[Aṣṭādhyāyī]]}}'' (अष्टाध्यायी). {{Unicode|Pāṇini’s}} grammar is highly systematized and technical. Inherent in its analytic approach are the concepts of the [[phoneme]], the [[morpheme]], and the [[Root (linguistics)|root]]; the phoneme was only recognized by Western linguists some two millennia later.
| |
|
| |
| In the [[Middle East]], the [[Persian language|Persian]] linguist [[Sibawayh]] made a detailed and professional description of [[Arabic language|Arabic]] in 760 CE in his monumental work, ''Al-kitab fi al-nahw'' (الكتاب في النحو, ''The Book on Grammar''), bringing many [[Linguistics|linguistic]] aspects of language to light. In his book he distinguished [[phonetics]] from [[phonology]].
| |
|
| |
| Later in the West, the success of [[science]], [[mathematics]], and other [[formal system]]s in the 20th century led many to attempt a formalization of the study of language as a "semantic code". This resulted in the [[academic discipline]] of [[linguistics]], the founding of which is attributed to [[Ferdinand de Saussure]].
| |
|
| |
| ::Where do Wittgenstein and Quine argue this? [[Philosopher]]s such as [[Ludwig Wittgenstein]], [[W. V. Quine]], and [[Jacques Derrida]] have disputed the possibility of such a rigorous study of language by questioning many of the assumptions necessary for such a study, and have put forth their own views on the nature of language. There is no end in sight to this debate.
| |
|
| |
| ===Language taxonomy===
| |
| The [[Taxonomic classification|classification]] of natural languages can be performed on the basis of different underlying principles (different closeness notions, respecting different properties and relations between languages); important directions of present classifications are:
| |
| * paying attention to the historical evolution of languages results in a genetic classification of languages—which is based on genetic relatedness of languages,
| |
| * paying attention to the internal structure of languages ([[grammar]]) results in a typological classification of languages—which is based on similarity of one or more components of the language's grammar across languages,
| |
| * and respecting geographical closeness and contacts between language-speaking communities results in areal groupings of languages.
| |
|
| |
| The different classifications do not match each other and are not expected to, but the correlation between them is an important point for many [[linguistics|linguistic]] research works. (There is a parallel to the classification of [[species]] in biological [[phylogenetics]] here: consider [[monophyletic]] vs. [[polyphyletic]] groups of species.)
| |
|
| |
| The task of genetic classification belongs to the field of [[historical-comparative linguistics]], of typological—to [[linguistic typology]].
| |
|
| |
| See also [[Taxonomy]], and [[Taxonomic classification]] for the general idea of classification and taxonomies.

| ====Genetic classification====
| |
| The world's languages have been grouped into families of languages that are believed to have common ancestors. Some of the major families are the [[Proto-Indo-European_language|Indo-European languages]], the [[Afro-Asiatic languages]], the [[Austronesian languages]], and the [[Sino-Tibetan languages]].
| |
|
| |
| The shared features of languages from one family can be due to shared ancestry. (Compare with [[homology (biology)|homology]] in biology.)
| |
|
| |
| ====Typological classification====
| |
| An example of a typological classification is the classification of languages on the basis of the basic order of the [[verb]], the [[subject (grammar)|subject]] and the [[object (grammar)|object]] in a [[sentence (linguistics)|sentence]] into several types: [[SVO language|SVO]], [[SOV language|SOV]], [[VSO language|VSO]], and so on, languages. ([[English language|English]], for instance, belongs to the [[SVO language]] type.)
| |
|
| |
| The shared features of languages of one type (= from one typological class) may have arisen completely independently. (Compare with [[analogy (biology)|analogy]] in biology.) Their cooccurence might be due to the universal laws governing the structure of natural languages—[[language universal]]s.
| |
|
| |
| ====Areal classification====
| |
| The following language groupings can serve as some linguistically significant examples of areal linguistic units, or ''[[sprachbund]]s'': [[Balkan linguistic union]], or the bigger group of [[European languages]]; [[Caucasian languages]]. Although the members of each group are not closely [[genetic relatedness of languages|genetically related]], there is a reason for them to share similar features, namely: their speakers have been in contact for a long time within a common community and the languages ''converged'' in the course of the history. These are called "[[areal feature (linguistics)|areal feature]]s".
| |
|
| |
| N.B.: one should be careful about the underlying classification principle for groups of languages which have apparently a geographical name: besides areal linguistic units, the [[taxa]] of the genetic classification ([[language family|language families]]) are often given names which themselves or parts of which refer to geographical areas.
| |
|
| |
| ===Constructed languages===
| |
| Humans have also deliberately contructed [[Constructed language|artificial language]]s such as [[Esperanto]], [[Lojban]], [[Ido]], [[Interlingua]], and [[Klingon language|Klingon]]. [[Esperanto]] is a well-known artificial language that was created by [[L. L. Zamenhof]] as a compilation of various elements of different languages, and was intended to be an easy-to-learn language for people familiar with similar languages.

A language is a system for encoding and decoding information. Determining what kinds of signals or symbols constitute language is not always a straightforward matter. Does the blossoming of a flower, whose color or scent signals to bees or birds to come and pollinate it, constitute a form of language? Does a skunk spraying constitute language, since it can certainly be said to be a form of communication? Are communications that involve, say, chemicals or pheromones part of some kind of language? Can we say that signaling behavior that is learned, rather than wired in, is language, whereas signaling behavior that is instinctive is not language?
The following article concerns language in all of its aspects. The definition of language - what counts as a language and what doesn't - is a difficult philosophical topic, deserving an article in its own right.
Human languages (Natural languages)
Human languages are usually referred to as natural languages, and the science of studying them is linguistics, but linguistics is not the only scholarly area with an interest in human languages. The discovery of the oldest evidence of language, primarily via vestiges of early writing, falls under the pervue of archaeology and also history. The mechanisms related to learning of human languages may be of interest in psychology and medicine due to its exercise of higher brain function. Computer scientists have been engaged in the study of human languages for the purpose of machine translation between different human languages.
Do animals have language?
Some animals communicate in a system which might be considered language, consisting either of calls or body postures used consistently for certain purposes and which are learned behavior. There are examples of multiple signals existing within one species, but signals are also sometimes used across species, such as when birds respond to chattering and tail waggles made by squirrels to warn of the presence of a predator.
The term "animal languages" is often used for non-human languages. Most researchers agree that these are not as complex or expressive as human language; they may better be described as animal communication. Some researchers argue that there are significant differences separating human language from the communication of other animals, and that the underlying principles are unrelated.
In several publicised instances, non-human animals have been trained to mimic certain features of human language. For example, chimpanzees and gorillas have been taught hand signs based on American Sign Language; however, they have never been successfully taught its grammar. There was also a case in 2003 of Kanzi, a captive bonobo chimpanzee allegedly independently creating some words to mean certain concepts. While animal communication has debated levels of semantics, it has not been shown to have syntax in the sense that human languages do.
Some researchers argue that a continuum exists among the communication methods of all social animals, pointing to the fundamental requirements of group behaviour and the existence of "mirror cells" in primates. This, however, may not be a scientific question, but is perhaps more one of definition. What exactly is the definition of the word "language"? Most researchers agree that, although human and more primitive languages have analogous features, they are not homologous.
Formal, mathematical, and computer languages
The activity of computer engineering has produced numerous computer programming languages, and in fact they have created several subfields of scholarly research relating to them, such as formal languages and compilers. Mathematicians have expressed various mathematical formalisms that they describe as languages.
