So well off with the quarter increase, gets all puffed up (7)
I believe the answer is:
swollen
'all puffed up' is the definition.
(I've seen this in another clue)
'so well off with the quarter' is the wordplay.
'off with' indicates anagramming the letters.
'the quarter' becomes 'n'.
'so'+'well'='sowell'
'sowell' with its letters mixed up with 'n' gives 'SWOLLEN'.
'increase gets' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for swollen that I've seen before include "Puffy" , "Greatly distended" , "Sell now (anag)" , "Bulging" , "Puffed up" .)
