idiom

This term describes expressions where the collective meaning diverges from the literal definitions of the individual words. It captures the cultural shorthand of a language, evoking a sense of insider knowledge and social belonging. Using such phrases correctly signals fluency and cultural integration, while literal interpretations often lead to confusion. In a broader linguistic sense, it refers to the stylistic fingerprint of a specific person or community. This encompasses not just fixed phrases, but the overall rhythm, vocabulary, and grammatical habits that distinguish one dialect or author from another.
