Idiolect
An individual's patterns of pronunciation and grammar of a language / From Wikipedia, the free encyclopedia
Not to be confused with Eye dialect or Ideologue.
Idiolect is an individual's unique use of language, including speech. This unique usage encompasses vocabulary, grammar, and pronunciation. This differs from a dialect, a common set of linguistic characteristics shared among a group of people.
The term is etymologically related to the Greek prefix idio- (meaning "own, personal, private, peculiar, separate, distinct") and -lect, abstracted from dialect,[1] and ultimately from Ancient Greek λέγω, légō, 'I speak'.
