Bump into agent that's brought over more stout? (7)
I believe the answer is:
plumper
'more stout?' is the definition.
(I've seen this before)
'bump into agent that's brought over' is the wordplay.
'bump into' becomes 'plum' (I am not sure about this - if you are sure you should believe this answer much more).
'agent' becomes 'rep' (short for representative).
'that's brought over' says the letters should be written in reverse.
'rep' back-to-front is 'per'.
'plum'+'per'='PLUMPER'
Can you help me to learn more?
(Other definitions for plumper that I've seen before include "more stout" , "One choosing" , "Fuller and rounder" .)
