Etymology

The word "mum" as a term for "mother" originated in the late 19th century as a childish or affectionate shortening of "mummy." Its use as an adjective meaning "silent" derives from the Middle English "mum," an imitative sound representing closed lips (like "mmm"), later associated with secrecy or silence (e.g., "mum's the word").
