About
The character "呒", whose traditional form is "嘸", combines the mouth radical (口) with the phonetic component "无" or "無", both meaning "not" or "without", indicating its association with verbal negation. Etymologically, it originated as a phonetic loan character used for representing sounds or interjections in classical Chinese. Its meaning later narrowed to express negation, particularly in Wu Chinese dialects where it signifies "not" or "without", as in "呒啥" for "nothing", while in standard Mandarin it has largely fallen out of common use.
