Bother, it's French bread (4)
I believe the answer is:
pain
I believe this clue is a double definition.
'bother' is the first definition.
(I know that bother can be written as pain)
'french bread' is the second definition.
(I've seen this before)
'it's' acts as a link.
(Other definitions for pain that I've seen before include "Unpleasant sensation" , "Sensation of hurt" , "great discomfort" , "French bread?" , "Mental distress" .)
