Blue wife died in parking space (5)
I believe the answer is:
bawdy
'blue' is the definition.
(synonyms)
'wife died in parking space' is the wordplay.
'wife' becomes 'w'.
'died' becomes 'd'.
'in' is an insertion indicator.
'parking space' becomes 'bay' (a parking bay).
'w'+'d'='wd'
'wd' put into 'bay' is 'BAWDY'.
(Other definitions for bawdy that I've seen before include "Humorously indecent" , "Lewd" , "Humorously obscene" , "Ribald" , "coarse" .)
