Pleased, content (4)
I believe the answer is:
glad
This clue is a double definition.
'pleased' is the first definition.
(similar in meaning)
'content' is the second definition.
(I've seen this in another clue)
(Other definitions for glad that I've seen before include "Feeling pleasure" , "Made up" , "Not sorry" , "Feeling happy" , "Pleased, delighted" .)
