Ungenerous (6)
'ungenerous' is the definition.
(I know that ungenerous can be written as stingy)
This is the entire clue.
(Other definitions for stingy that I've seen before include "Mean, parsimonious - ouch?" , "Informally mean like aggressive wasp?" , "Mean and grudging" , "Zola cocotte; Darlings' dog (Barrie)" , "Parsimonious like nettle?" .)
(Other definitions for measly that I've seen before include "Contemptibly small in amount" , "Miserably paltry" , "Spotty - paltry" , "ungenerous in amount" , "Slay me (anag)" .)
