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' mixed up with 'n' can make 'SWOLLEN'.
'increase gets' acts as a link.
This may not be correct. Some or all of it may belong to 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" .)
