Good meat left for male pig (7)
I believe the answer is:
glutton
'pig' is the definition.
(I've seen this before)
'good meat left for male' is the wordplay.
I cannot quite understand how this works, but
'good' could be 'g' (abbreviation) and 'g' is present in the answer.
'left' could be 'l' (common abbreviation) and 'l' is located in the answer.
'for' could be 'to' (eg both can mean 'in the opinion of') and 'to' is found in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for glutton that I've seen before include "Gormandizer" , "Immoderate eater" , "One who eats to excess" , "Forest animal" , "Big eater" .)
