Great pleasure or satisfaction (7)
I believe the answer is:
delight
This clue is a double definition.
'great pleasure' is the first definition.
(I've seen this before)
'satisfaction' is the second definition.
(I have seen 'Extreme satisfaction' mean 'delight' so perhaps 'satisfaction' could also mean 'delight')
(Other definitions for delight that I've seen before include "Greatly please" , "entrance?" , "Gladden" , "Captivate" , "Joy" .)
