Little winger misused towel (5)
I believe the answer is:
owlet
'little winger' is the definition.
'owlet' can be an answer for 'winger' (owlet is a kind of bird). I am not certain of the 'little' bit.
'misused towel' is the wordplay.
'misused' indicates anagramming the letters.
'towel' is an anagram of 'OWLET'.
Can you help me to learn more?
(Other definitions for owlet that I've seen before include "Young nocturnal flier" , "Baby bird; moth" , "who'll give a hoot?" , "Young bird of the night" , "Wise avian's youngster?" .)
