Blustery fellow goes around the street (5)
I believe the answer is:
gusty
'blustery' is the definition.
(synonyms)
'fellow goes around the street' is the wordplay.
'fellow' becomes 'guy' (both can mean a man).
'goes around' indicates putting letters inside.
'the street' becomes 'st' (abbreviation).
'guy' placed around 'st' is 'GUSTY'.
(Other definitions for gusty that I've seen before include "Of wind, blowing in bursts" , "Blowing intermittently" , "Windy" .)
