Pleased everything included (7)
I believe the answer is:
content
'pleased' is the definition.
(associated in meaning)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for content that I've seen before include "Peacefully happy" , "state of peaceful happiness" , "Satisfied, happy enough" , "Satisfied - subject matter" , "Quietly happy" .)
