One who quickly eats some turkey (7)
I believe the answer is:
gobbler
'some turkey' is the definition.
(gobbler is a kind of turkey)
'one who quickly eats' is the wordplay.
I cannot really understand how this works, but
'one' could be 'er' (I've seen this in other clues) and 'er' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for gobbler that I've seen before include "Male turkey" , "One quickly eating - turkey" .)
