Performer, Poet Laureate: “What’s coming on Monday?” (6)
I believe the answer is:
player
'performer' is the definition.
(I know that player is a type of performer)
'poet laureate what's coming on monday?' is the wordplay.
'poet laureate' becomes 'PL' (abbreviation).
'what's coming on monday?' becomes 'ayer' (I can't justify this - if you can you should give a lot more credence to this answer).
'pl'+'ayer'='PLAYER'
Can you help me to learn more?
(Other definitions for player that I've seen before include "Performer" , "South African golfer, b. 1935" , "Important participant" , "Sportsman - instrumentalist" , "Contestant" .)
