Vocabulary choices that reflect membership in a social group describe which term?

• A. Sociolect
• B. Accent
• C. Grammar
• D. Idiom

Answer: (A)

Sociolect describes the vocabulary and language choices that signal membership in a particular social group. People adopt specific words, slang, and lexical styles that align with a community—such as a profession, age group, cultural background, or subculture—so the words a person selects reveal their group affiliation. The focus on vocabulary reflecting social membership is what makes sociolect the best fit.

An accent is about pronunciation, not the actual words used. Grammar concerns the rules that govern sentence structure, not the choice of vocabulary. An idiom refers to a fixed expression whose meaning isn’t directly tied to the individual words, rather than to belonging to a social group.
