Player of current high prominence (5)
I believe the answer is:
actor
'player' is the definition.
(synonyms)
'current high prominence' is the wordplay.
'current' becomes 'ac' (alternating current).
'high prominence' becomes 'tor' (I've seen this in another clue. I am not sure about the 'high' bit.).
'ac'+'tor'='ACTOR'
'of' is the link.
Can you help me to learn more?
(Other definitions for actor that I've seen before include "I pretend" , "Stage-player" , "Theatre player" , "Cruise, e.g." , "Films/stage worker" .)
