Side winds (4)
I believe the answer is:
airs
I believe this is a double definition.
'side' is the first definition.
(thesaurus)
'winds' is the second definition.
(air is a kind of wind)
(Other definitions for airs that I've seen before include "Arrogance" , "Affected manners" , "affectation of superiority" , "Melodies or artificial manners" , "Tunes and posturings" .)
