Silent parent (3)

Ross

I believe the answer is:

mum

I believe this is a double definition.

'silent' is the first definition.
(keep mum)

'parent' is the second definition.
(mum means a mother)

(Other definitions for mum that I've seen before include "Parent (who's kept or is the word!)" , "Mother - she's the word for secrecy" , "Parent - shtoom" , "Palindromic mater" , "old lady" .)

I've seen this clue in the Evening Standard and The Times.
