Fabulous steed's quiet, say, like our lot (7)
I believe the answer is:
pegasus
'fabulous steed's quiet say like our lot' is the definition.
I can't judge whether this defines the answer.
'quiet say like our lot' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'say' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'like' becomes 'as'.
'our lot' becomes 'us'.
'p'+'eg'+'as'+'us'='PEGASUS'
Can you help me to learn more?
(Other definitions for pegasus that I've seen before include "Mythical winged horse" , "fabulous horse" , "Winged horse - constellation" , "Immortal winged horse of Greek mythology" , "Fish" .)
