Possibly fitter bowler? (6)
I believe the answer is:
titfer
'bowler?' is the definition.
Both the answer and definition are singular nouns.
Maybe there's a link between them I don't understand?
'possibly fitter' is the wordplay.
'possibly' indicates anagramming the letters.
'fitter' is an anagram of '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" .)
