Gets bigger toffs? (6)
I believe the answer is:
swells
This clue could be a double definition.
'gets' is the first definition.
The answer and definition can be both related to change as well as being verbs in their -s form.
Maybe they are linked in a way I don't understand?
'bigger toffs?' is the second definition.
The definition and answer can be both people as well as being plural nouns.
Maybe you can see an association between them that I can't see?
Can you help me to learn more?
(Other definitions for swells that I've seen before include "Grows larger like posh people" , "Becomes larger in size for posh people" , "VIPs" , "Inflates like posh people" , "Inflates like colloquial toffs" .)
