What does idiolect mean?
An idiolect is the particular form of language used by one person, characterized by choices of vocabulary, grammar, pronunciation, syntax, and style. Unlike a dialect, which is generally shared by a community, an idiolect is an individual variety shaped by a speaker's family, education, occupation, region, and other influences. The term is used in linguistics to study variation between individual speakers, and in literary criticism to describe an author's distinctive verbal style. In everyday discussion, “idiolect” can suggest a recognizable personal voice, although the word remains more technical than terms such as “voice” or “style.” The concept is useful because it shows that speaking and writing are not entirely standardized: people develop systematic linguistic habits that distinguish them from others while still participating in wider varieties of language.

Where does idiolect come from?
Idiolect comes from the Greek adjective idiōlek tos, meaning “peculiar to one” or “private.” It combines idiōlēktos, formed from idios (“one's own” or “private”) and lēktos (“chosen” or “speech”), with the English suffix -ect, meaning “a form or selection.” Its historical development follows the wider use of Greek-derived idio- terms in English, including idiom and idiomatic.
