Demonstrator being theatrical? (7)
I believe the answer is:
showman
'theatrical?' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'demonstrator being' is the wordplay.
'demonstrator' becomes 'show' (I can't justify this - if you can you should give a lot more credence to this answer).
'being' becomes 'man' (man is a kind of being).
'show'+'man'='SHOWMAN'
Can you help me to learn more?
(Other definitions for showman that I've seen before include "Circus or fair manager" , "Impresario" , "Person helping to present" , "Circus proprietor" , "Entertainer" .)
