Cook gets round a heavy fellow (7)
I believe the answer is:
gorilla
'heavy fellow' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'cook gets round a' is the wordplay.
I cannot quite understand how this works, but
'round' could be 'o' (o is a circular letter) and 'o' is located in the answer.
'cook' could be 'grill' (grilling is a form of cooking) and 'grill' is located in the leftover letters.
'a' is found in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for gorilla that I've seen before include "Large primate" , "brutal man" , "Big ape" , "African great ape" , "Large animal" .)
