Requests said to give satisfaction (5)
I believe the answer is:
pleas
'requests' is the definition.
(plea is a kind of request)
'said to give satisfaction' is the wordplay.
'said' shows a homophone (sound like).
'to give satisfaction' becomes 'please' (I've seen this before).
'please' is a homophone of 'PLEAS'.
(Other definitions for pleas that I've seen before include "Entreats" , "Excuses, pretexts" , "Urgent entreaties" .)
