Asleep, roused to give satisfaction (6)
I believe the answer is:
please
'give satisfaction' is the definition.
(I've seen this in another clue)
'asleep roused' is the wordplay.
'roused' is an anagram indicator (I've seen this in other clues).
'asleep' is an anagram of 'PLEASE'.
'to' acts as a link.
(Other definitions for please that I've seen before include "Gratify as by a sleep" , "Delight; amuse" , "Cause (someone) to feel satisfied" , "Like" , "Delight, satisfy" .)
