Gives nothing to me, though generous (8)
I believe the answer is:
handsome
'generous' is the definition.
('handsome' can be similar in meaning to 'generous')
'gives nothing to me' is the wordplay.
'gives' becomes 'hands' ('hand' can be a synonym of 'give'**).
'nothing' becomes 'o' (looks like zero - 0).
'hands'+'o'+'me'='HANDSOME'
'though' is the link.
(Other definitions for handsome that I've seen before include "Easy on the eye" , "Pleasing to see" , "Good-looking or generous" , "large" , "Well-proportioned" .)
