Theatre review -- nothing unusual about this writer (10)
I believe the answer is:
auditorium
'theatre' is the definition.
(thesaurus)
'review nothing unusual about this writer' is the wordplay.
I cannot quite see how this works, but
'review' could be 'audit' (I've seen this before) and 'audit' is found in the answer.
'nothing' could be 'o' (looks like zero - 0) and 'o' is found within the answer.
'writer' could be 'i' (the person who is writing these clues) and 'i' is present in the answer.
'unusual' could be 'rum' (I've seen this before) and 'rum' is found in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for auditorium that I've seen before include "Space for an audience" , "place for concertgoers" , "Body of theatre" , "Space for listeners" , "Performance hall" .)
