Entrap drunken mum? (6)
I believe the answer is:
'mum?' is the definition.
(mum is a kind of parent)
'entrap drunken' is the wordplay.
'drunken' indicates an anagram.
'entrap' anagrammed gives 'PARENT'.
(Other definitions for parent that I've seen before include "One with offspring" , "Trepan for progenitor" , "Mother or father or what they do" , "Author" , "Begetter of offspring" .)
