A sociolect refers to the distinct language features, vocabulary, and expressions used by a particular social group, often shaped by factors such as class, age, ethnicity, or profession. This speech variety reflects the identity and culture of the group, distinguishing it from other dialects and registers. Unlike regional dialects, which are geographically based, sociolects arise from social dynamics and interactions within specific communities, highlighting how language can serve as a marker of social belonging and group identity.
