In
linguistics, a
register is a
variety of a
language used for a particular purpose or in a particular social setting. For example, when speaking in a formal setting contrary to an informal setting, an
English speaker may be more likely to use features of
prescribed grammar—such as pronouncing words ending in
-ing with a
velar nasal instead of an
alveolar nasal (e.g. "walking", not "walkin'"), choosing more formal words (e.g.
father vs.
dad, child vs.
kid, etc.), and refraining from using words considered nonstandard, such as
ain't.
