To whom work is play? (5)
I believe the answer is:
actor
'play?' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'to whom work' is the wordplay.
I cannot really see how this works, but
'to' is found in the answer.
This explanation may well be incorrect...
'is' is the link.
Can you help me to learn more?
(Other definitions for actor that I've seen before include "One with role" , "Theatre player" , "Cruise, e.g." , "Thespian, stage performer" , "One on stage" .)
