An idiolect is a variety of a language unique to an individual. It is manifested by patterns of word selection and grammar, or words, phrases, idioms, or pronunciations that are unique to that individual. Every individual has an idiolect; the grouping of words and phrases is unique, rather than an individual using specific words that nobody else uses. An idiolect can easily evolve into an ecolect—a dialect variant specific to a household.
