Choose stout (5)
I believe the answer is:
plump
This clue is a double definition.
'choose' is the first definition.
(I know that plump has the is a more specific form of the action choose)
'stout' is the second definition.
(I've seen this before)
(Other definitions for plump that I've seen before include "Slightly fat" , "Not obese, just pleasantly rounded" , "Opt - round" , "Rotund" , "Having a full rounded shape" .)
