Cheerful in the wind? (6)
I believe the answer is:
breezy
'cheerful' is the definition.
(thesaurus)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for breezy that I've seen before include "Windy - upbeat" , "Fresh - jaunty" , "With light winds" , "Pleasantly windy" , "Lively - exhilarating" .)
