Which term best describes language features shaped by social identity?

• A. Sociolect
• B. Register
• C. Dialect
• D. Idiom

Answer: (A)

Sociolect is the term that describes language features shaped by social identity. It refers to the way a social group tends to speak—its vocabulary, pronunciation, grammar, and usage patterns—because of who its members are (age, class, ethnicity, occupation, community, and other identity factors). This helps explain why different groups within the same region might have distinct speech styles that signal belonging to that group, beyond just where they live or the situation they’re in.

In contrast, dialect is about regional variation in speech, not the social identities of speakers. Register relates to how language shifts with context and purpose (formal vs. informal, professional vs. casual), and idiom is about fixed expressions whose meanings aren’t deducible from the individual words and doesn’t inherently reflect social grouping.
