Blustering about desire (4)
I believe the answer is:
lust
'desire' is the definition.
(I know that lust is a more specific form of the action desire)
'blustering about' is the wordplay.
'about' says the answer is hidden in the clue (the clue goes around or about the answer).
'LUST' is hidden within 'blustering'.
(Other definitions for lust that I've seen before include "Depraved desire" , "Deadly sin of extreme passion" , "Passionate desire" , "Libido" , "Strong sexual desire" .)
