Shell daughter removed from window (5)
I believe the answer is:
ormer
'shell' is the definition.
(I've seen this before)
'daughter removed from window' is the wordplay.
'daughter' becomes 'd'.
'removed from' suggests deleting specific letters.
'window' becomes 'dormer' (dormer is a kind of window).
'dormer' with 'd' taken out is 'ORMER'.
(Other definitions for ormer that I've seen before include "Ear-shell" , "sea creature" , "Seafood" , "Shellfish" , "Edible abalone; rhymes with projecting window" .)
