Winged horse, — quiet. say, like you and me (7)
I believe the answer is:
pegasus
'winged horse' is the definition.
(I've seen this before)
'quiet say like you and me' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'say' becomes 'eg' (both can mean for example).
'like' becomes 'as'.
'you and me' becomes 'us' (the two of us).
'p'+'eg'+'as'+'us'='PEGASUS'
(Other definitions for pegasus that I've seen before include "Flier" , "Inspirational figure" , "Northern hemisphere constellation - use gaps (anag)" , "Winged horse - constellation" , "Winged horse of Greek myth" .)
