Colloquial is often mistakenly used with a connotation of disapproval, as if it meant “vulgar” or “bad” or “incorrect” usage, whereas it is merely a familiar style used in speaking and writing. Conversational refers to a style used in the oral exchange of ideas, opinions, etc.: an easy conversational style. Informal means without formality, without strict attention to set forms, unceremonious: an informal manner of speaking; it describes the ordinary, everyday language of cultivated speakers.
