Stiff grass around yard (4)
I believe the answer is:
body
'stiff' is the definition.
(I know that stiff can be written as body)
'grass around yard' is the wordplay.
'grass' becomes 'dob' (I can't explain this - if you can you should give a lot more credence to this answer).
'around' says the letters should be written in reverse.
'yard' becomes 'y' (abbreviation).
'dob' back-to-front is 'bod'.
'bod'+'y'='BODY'
Can you help me to learn more?
(Other definitions for body that I've seen before include "Cadaver" , "Individual" , "One-piece undergarment for women, covering the torso" , "welcomed in Madeira" , "Group of people" .)
