Could be a codger's final resting place (4,4)
I believe the answer is:
gods acre
'resting place' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see an association between them that I can't see?
'could be a codger's final' is the wordplay.
'could be' indicates an anagram.
'final' is a charade indicator (letters next to each other).
'a'+'codgers'='acodgers'
'acodgers' anagrammed gives 'GODS ACRE'.
Can you help me to learn more?
(Other definitions for gods acre that I've seen before include "ground near church" , "Remains here" , "'Churchyard (4,4)'" , "Burial ground" , "burial-ground" .)
