Puts up with most cash being squandered (8)
I believe the answer is:
stomachs
'puts up with' is the definition.
('stomach' can be a synonym of 'put up with')
'most cash being squandered' is the wordplay.
'being squandered' is an anagram indicator (I've seen this in other clues).
'most'+'cash'='mostcash'
'mostcash' anagrammed gives 'STOMACHS'.
(Other definitions for stomachs that I've seen before include "Four of these for bulls" , "Saclike organs of bodies" , "Saclike organs of the body" , "Tummies" , "bibles, for example" .)
