One intending to be less generous (6)
I believe the answer is:
meaner
I believe this is a double definition.
'one intending' is the first definition.
(someone meaning or intending something)
'less generous' is the second definition.
(I've seen this in another clue)
'to be' acts as a link.
(Other definitions for meaner that I've seen before include "More stingy or parsimonious" , "Less generous" , "Rename as being more stingy" , "Rename (anag.)" , "Rename as being stingier" .)
