Miserable sounding, what the wind did (4)
I believe the answer is:
blew
'what the wind did' is the definition.
(the wind blows)
'miserable sounding' is the wordplay.
'miserable' becomes 'blue'.
'sounding' indicates a 'sounds like' (homophone) clue.
'blue' is a homophone of 'BLEW'.
(Other definitions for blew that I've seen before include "spent freely" , "Sounded (a horn)" , "Squander in the past" , "Bungled (an opportunity)" , "Spent recklessly; exploded suddenly" .)
