Unwanted breeze (5)
I believe the answer is:
draft
'unwanted breeze' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for draft that I've seen before include "Current of air or preliminary version" , "Early version of text" , "conscript" , "A money order for US conscription" , "Sketch - detachment of men" .)
