Excessive praise (8)
I believe the answer is:
flattery
'excessive praise' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for flattery that I've seen before include "Soft soap" , "phony praise" , "Obsequious praise" , "''Imitation is the sincerest form of . . . . . . . .'' (8)" , "sugar?" .)
