One getting large in stomach, putting on weight? (7)
I believe the answer is:
glutton
'one getting large in stomach putting on weight?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'getting large in stomach putting on weight?' is the wordplay.
'getting' is an insertion indicator.
'large' becomes 'l'.
'in stomach' becomes 'gut' (I've seen this before. I am not sure about the 'in' bit.).
'putting on' means one lot of letters go next to another.
'weight?' becomes 'ton' (ton is a kind of weight).
'l' inserted within 'gut' is 'glut'.
'glut'+'ton'='GLUTTON'
Can you help me to learn more?
(Other definitions for glutton that I've seen before include "Gormandizer" , "Gourmand" , "Greedy guts" , "Excessive eater; wolverine" , "Greedy type" .)
