The bit where they divorce? (4)
I believe the answer is:
part
This clue might be a double definition.
'the bit' is the first definition.
(I've seen this in other clues)
'they divorce?' is the second definition.
'part' can be an answer for 'divorce?' (thesaurus). I'm not certain of the 'they' bit.
'where' acts as a link.
Can you help me to learn more?
(Other definitions for part that I've seen before include "Divide; role" , "Region" , "Fraction of the whole - separate" , "Bit - leave" , "Element" .)
