Liquid asset in the theatre, etc. (5)
I believe the answer is:
seats
'the theatre etc' is the definition.
I can't judge whether this definition defines the answer.
'liquid asset' is the wordplay.
'liquid' indicates anagramming the letters.
'asset' anagrammed gives 'SEATS'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for seats that I've seen before include "Parliamentary constituencies" , "Chairs, stools" .)
