Blustery fellow embraces good man (5)
I believe the answer is:
gusty
'blustery' is the definition.
(synonyms)
'fellow embraces good man' is the wordplay.
'fellow' becomes 'guy' (both can mean a man).
'embraces' means one lot of letters goes inside another.
'good man' becomes 'st' (abbreviation for saint).
'guy' enclosing 'st' is 'GUSTY'.
(Other definitions for gusty that I've seen before include "Of wind, blowing in bursts" , "Blowing intermittently" , "Windy" .)
