We cut grass before husband's fury (5)
I believe the answer is:
wrath
'fury' is the definition.
(I know that wrath is a type of fury)
'we cut grass before husband's' is the wordplay.
'cut' means to remove the last letter.
'grass' becomes 'rat' (both can mean a snitch or informer).
'before' means one lot of letters go next to another.
'husband' becomes 'h'.
'we' with its final letter taken away is 'w'.
'w'+'rat'+'h'='WRATH'
(Other definitions for wrath that I've seen before include "Fury" , "Violent anger" , "` `A soft answer turneth away .....' '" , "Ire" , "Extreme anger" .)
