Sound excuses gives satisfaction (6)
I believe the answer is:
please
'sound excuses gives satisfaction' is the definition.
I can't judge whether this defines the answer.
'sound excuses' is the wordplay.
'sound' shows a homophone (sound like).
'excuses' becomes 'pleas' (I've seen this in another clue).
'pleas' sounds like 'PLEASE'.
Can you help me to learn more?
(Other definitions for please that I've seen before include "See pal (anag) -- charm" , "If you'd be so kind?" , "Make glad, being asleep" , "Beatles song (request to oblige?)" , "Give satisfaction to" .)
