The particular version of a language used by those who are members of a large group (i.e. inhabitants of the same geographical region or members of the same socio-economic class).

Language variation describes the many different ways we use the English language. Sometimes it seems as if we are chameleons, changing our tone, register, level of formality and choice of vocabulary according to the situation. Sometimes people even change their accent or dialect in order to avoid being judged negatively by others.
