Can toff get bigger? (5)
I believe the answer is:
swell
This could be a double definition.
'can toff' is the first definition.
'swell' can be an answer for 'toff' (wealthy or high-class person). I am unsure of the 'can' bit.
'get bigger?' is the second definition.
(I've seen this in another clue)
Can you help me to learn more?
(Other definitions for swell that I've seen before include "Bulge; a toff" , "marvellous" , "Waves - get bigger" , "Person of high social standing" , "Grand" .)
