In linguistics, an accent is a manner of pronunciation of a language. Accents can be confused with dialects which are varieties of language differing in vocabulary, syntax, and morphology, as well as pronunciation. Dialects are usually spoken by a group united by geography or social status. Children are able to take on accents at a fast rate; children of traveling families, for example, can change their accents within a short period of time. This generally remains true until a person's early twenties, after which, a person's accent seems to become more entrenched.
