More than a little unkind (4)
I believe the answer is:
mean
'more than a little unkind' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for mean that I've seen before include "Close" , "'Midway, average (4)'" , "Signify; miserly" , "Unkind; average" , "middle course" .)
