Blessed with not so much (4)
I believe the answer is:
less
'not so much' is the definition.
(I've seen this before)
'blessed with' is the wordplay.
'with' says the answer is hidden in the clue.
'LESS' is hidden in the letters of 'blessed'.
(Other definitions for less that I've seen before include "Smaller in amout or degree" , "A smaller amount" , "Comparative of 'a little'" , "So-called St James" , "Minus; not so much" .)
