Mean, ungenerous (6)
I believe the answer is:
stingy
I believe this clue is a double definition.
'mean' is the first definition.
(both can mean miserly)
'ungenerous' is the second definition.
(associated in meaning)
(Other definitions for stingy that I've seen before include "Wasps are" , "Mean, tight" , "near" , "Informally mean like aggressive wasp?" , "Mean and grudging" .)
