Should he be a good liar? (5)
I believe the answer is:
actor
This might be a double definition.
'should he' is the first definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'a good liar?' is the second definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'be' acts as a link.
Can you help me to learn more?
(Other definitions for actor that I've seen before include "eg Anthony Hopkins" , "Thesp" , "Dramatic artist" , "Theatre player" , "Person performing on stage or screen" .)
