Treated with excessive indulgence (8)
I believe the answer is:
pampered
'treated with excessive indulgence' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for pampered that I've seen before include "mollycoddled" , "Warwickshire cricket ground" , "Treated with excessive indulgence" , "Spoiled" , "Did baby" .)
