Actor or egg producer on the quiet (6)
I believe the answer is:
player
'actor' is the definition.
(synonyms)
'egg producer on the quiet' is the wordplay.
I cannot quite see how this works, but
'quiet' could be 'p' (music symbol for 'piano', ie soft or quiet) and 'p' is present in the answer.
The remaining letters 'layer' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'or' acts as a link.
Can you help me to learn more?
(Other definitions for player that I've seen before include "Active sportsperson" , "Competitor; musician" , "Person who takes part in a game" , "Gambler" , "Sports participant" .)
