Possibly fitter bowler? (6)
I believe the answer is:
titfer
'bowler?' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see a link between them that I don't see?
'possibly fitter' is the wordplay.
'possibly' is an anagram indicator.
'fitter' with letters rearranged gives 'TITFER'.
Can you help me to learn more?
(Other definitions for titfer that I've seen before include "Fitter (anag.)" , "Cockney rhyming slang for hat" , "A Cockney's hat" , "Hat (informal)" , "tile" .)
