Indulge, spoil (6)
I believe the answer is:
pamper
This clue is a double definition.
'indulge' is the first definition.
(I know that indulge can be written as pamper)
'spoil' is the second definition.
(I know that spoil can be written as pamper)
(Other definitions for pamper that I've seen before include "Mollycoddle" , "baby" , "Overindulge (someone)" , "Treat with excessive indulgence" , "Treat luxuriously" .)
