Mums the Word Origin

So, where did “mums the word” originate? There is no clear evidence pointing to the coining of the phrase. However, some experts think that “mums the word” derives from the word “Mummer.” Back in medieval times, a mummer was a person that could not speak or was not allowed to speak.

They would perform dances, plays, or games in silence to amuse the royalty. In Philadelphia, there is a festival keeping the tradition alive and well, with “Mummers day” being a popular event held each year on New Year’s Day.

Other language experts believe the phrase comes from the Shakespeare play, Henry VI, Part 2. Shakespeare penned the play in 1592, and Part 2 has the line, “Seal up your lips and give no words but mum.”

This use of the word has nothing to do with depicting the mother figure of the household. Mum is a popular colloquialism for mothers in the UK, but not in this reference.

Another version of the phrase is “mum is counsel,” used up to the 16th century. The earliest reference of this phrase comes from “A Walk Around London and Westminster – The Works of Mr. Thomas Brown,” authored in 1720.
