Blustered about appetite (4)
I believe the answer is:
lust
'appetite' is the definition.
(thesaurus)
'blustered about' is the wordplay.
'about' indicates a hidden word (the clue goes around or about the answer).
'LUST' can be found hidden inside 'blustered'.
(Other definitions for lust that I've seen before include "Deadly sin of extreme passion" , "Strong sexual desire" , "Intense sexual desire, a deadly sin" , "Depraved desire" , "Lecherousness" .)
