What does mum mean and who uses it?


Mum is an endearing way to refer to a mother. It is primarily used in British English but may also be used in American English as an alternative to "Mom."

Some see "Mum" as a lazier version of "Mom" because the "u" is easier to say than the hard "o." This is why it is considered a slang term by some people. Mum may also be used as an alternative to "silent," like in the "Mum's the word" phrase.


I love my mum!
