Get browned off about theatre that’s boring (6)
I believe the answer is:
trepan
'boring' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'get browned off about theatre' is the wordplay.
'get browned off' becomes 'tan' (get a tan).
'about' is an insertion indicator.
'theatre' becomes 'rep' (repertory theatre).
'tan' placed around 'rep' is 'TREPAN'.
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for trepan that I've seen before include "cut through bone" , "Surgical saw" , "Make a hole in skull" , "Make perforation in person's skull" , "Surgically create a hole in the skull" .)
