language variety used by a population in their public discourse (for public purposes); standardized language that has at least one standard variety besides its other varieties; variety that has undergone standardization

Dialectologists investigate differences in pronunciation, grammar, and vocabulary, and how such differences pattern across communities and change over time.

a way of pronouncing a language that is distinctive to a country, area, social class, or individual

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.

In sociolinguistics, a sociolect is a form of language (non-standard dialect, restricted register) or a set of lexical items used by a socioeconomic class, profession, age group, or other social group.

A diaphoneme is an abstract phonological unit that identifies a correspondence between related sounds of two or more varieties of a language or language cluster. For example, some English varieties contrast the vowel of late () with that of wait or eight (). Other English varieties contrast the vowel of late or wait () with that of eight (). This non-overlapping pair of phonemes from two different varieties can be reconciled by positing three different diaphonemes: A first diaphoneme for words like late (), a second diaphoneme for words like wait (), and a third diaphoneme for words like eight
