Dry suggestion that you can't spell too well? (5)
I believe the answer is:
towel
'dry' is the definition.
(thesaurus)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for towel that I've seen before include "Owlet (anag)" , "Drier" , "Bathroom cloth" , "Bathroom item" , "what sweater needs?" .)
