Fading and dingy, maybe (5)
I believe the answer is:
dying
'fading' is the definition.
(thesaurus)
'dingy maybe' is the wordplay.
'maybe' indicates anagramming the letters.
'dingy' is an anagram of 'DYING'.
'and' acts as a link.
(Other definitions for dying that I've seen before include "On one's last legs" , "Starting to stop!" , "Failing to get laughs" , "final" , "Coluring, hair or fabric" .)
