Give satisfaction (6)
I believe the answer is:
please
'give satisfaction' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for please that I've seen before include "Entertain" , "Make glad, being asleep" , "Gratify, make contented" , "Cause (someone) to feel satisfied" , "Polite word of request" .)
