A language is a system of symbols, generally known as words, and the grammatical and other rules by which they are manipulated. The word language is also used to refer to the whole phenomenon of language, and in this sense language is one of several forms of human communication. The scientific study of language and languages, including their historical development, characteristics, and use in society, is the field of linguistics.
Human language is a natural phenomenon, and language learning is instinctive in childhood. In using language, people use patterns of sound or gesture to convey the words and rules of language, or they represent these patterns in codes such as writing. There are thousands of languages, historically related to each other in many language families, and they share a number of common properties. Besides using naturally acquired language, people have consciously crafted languages such as Esperanto and Klingon.
In phonetics, a vowel is a sound in spoken language, such as an English ah! [ɑː] or oh! [oʊ], pronounced with an open vocal tract so that there is no build-up of air pressure at any point above the glottis. This contrasts with consonants, such as English sh! [ʃː], where there is a constriction or closure at some point along the vocal tract. A vowel is also understood to be syllabic: an equivalent open but non-syllabic sound is called a semivowel.
In all oral languages, vowels form the nucleus or peak of syllables, whereas consonants form the onset and (in languages that have them) coda. However, some languages also allow other sounds to form the nucleus of a syllable, such as the syllabic l in the English word table [ˈteɪ.bl̩] (the stroke under the l indicates that it is syllabic; the dot separates syllables), or the r in Serbo-Croatian vrt [vr̩t] "garden".
