Mum's the word is a popular English idiom. It is related to an expression used by William Shakespeare, in Henry VI, Part 2.[1]
The word "mum" is an alteration of momme, which was used between 1350 and 1400 in Middle English with very close to the same meaning, "be silent; do not reveal".
Meaning
edit"Mum's the word" means to keep silent or quiet.
Mum is a Middle English word meaning 'silent',[2] and may be derived from the mummer who acts without speaking.[3] Note the similar English word "mime" (Old English "mīma", Latin "mimus") meaning silent actor or imitator.
Origin
editThe origins of the phrase can be traced back to the fourteenth century and William Langland's narrative poem, Piers Plowman:
Thou mightest beter meten the myst on Malverne hulles
Then geten a mom of heore mouth til moneye weore schewed!
It can also be seen in popular fifteenth-century Towneley Plays:[4]
Though thi lyppis be stokyn, yit myght thou say 'mum'.
The phrase notably appears in Shakespeare's Henry VI, Part 2, Act 1, Scene 2:
Seal up your lips and give no words but mum.
