Giving little ground eg on run with Sue (10)
I believe the answer is:
ungenerous
'giving little' is the definition.
(generous can mean giving)
'ground eg on run with sue' is the wordplay.
'ground' indicates anagramming the letters ('grind' the letters into a new form).
'with' means one lot of letters go next to another.
'eg'+'on'+'run'='egonrun'
'egonrun' after 'sue' is 'sueegonrun'.
'sueegonrun' is an anagram of 'UNGENEROUS'.
(Other definitions for ungenerous that I've seen before include "Mean" , "despising charity" .)
