Bed woman, having had bottom pinched (5)
I believe the answer is:
berth
'bed' is the definition.
(berth is a kind of bed)
'woman having had bottom pinched' is the wordplay.
'woman' becomes 'Bertha'.
'having had bottom pinched' means to remove the last letter (in a down clue, the bottom letter is removed).
'bertha' with its final letter taken away is 'BERTH'.
(Other definitions for berth that I've seen before include "Place to sleep on a ship" , "Bunk; mooring place" , "Bunk on board" , "Place to lie down on train or ship" , "Bed on a ship/train" .)
