Word Nuance & Usage

A colloquialism is often confused with slang; however, colloquialisms are everyday informal expressions understood by the general population (such as "gonna" or "y'all"), whereas slang is typically restricted to specific subcultures or age groups.

Word Origin & Etymology

Formed in the early 19th century from "colloquial" plus the suffix "-ism", ultimately deriving from the Latin "colloquium" (conversation), from "com-" (together) and "loqui" (to speak).
