Squander; strong wind (4)
I believe the answer is:
blow
I believe this is a double definition.
'squander' is the first definition.
(synonyms)
'strong wind' is the second definition.
(thesaurus)
(Other definitions for blow that I've seen before include "Clip" , "Strong current of air" , "Shock; sound (a horn)" , "Gust" , "Cuff" .)
