Naturally a crow may carry on eating it (7)
I believe the answer is:
carrion
'it' is the definition.
The definition suggests a singular noun which matches the answer.
'naturally a crow may carry on eating' is the wordplay.
I cannot quite understand how this works, but
'a' is found in the answer.
'on' is within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for carrion that I've seen before include "Rotting dead body of an animal" , "Decaying animal flesh" , "rotten" , "Dead flesh (for e.g. crow)" , "Dead flesh for food" .)
