More About Mum

doesmum mean?

Mum is an adjective that means keeping quiet. It can also be used by itself to mean Be quiet!

This sense of mum is especially used in the expressions keep mum and mum’s the word.

In the U.K. and other places, mum is used as a word for mom or madam. It’s also commonly used as a short way of saying chrysanthemum, a type of flower.

Example: Mum’s keeping mum—I can’t get a word out of her!

Where doesmum come from?

Mum in the sense of “silent” comes from the Middle English word momme, which is probably imitative of the sound that a closed mouth makes. Go ahead—try it. It sounds like mumbling, right? Well, the word mumble is based on the same word.

Most likely, your mum has told you not to mumble. And she’s probably also told you on many occasions to keep quiet, or keep mum. The idea behind the instruction—and the origin of the word—is that the mouth should be closed. Somewhat relatedly, the word for mother in many languages around the world begins with the m sound, which is also made with the mouth closed (and is one of the first sounds babies learn how to make).

When used to mean “madam,” mum is a variation of ’a, which is a shortening of madam.

Mum can also be used as a verb meaning to “act as a mummer,” a kind of costumed performer.
