Fight for theatre seats? (3)
I believe the answer is:
box
This clue might be a double definition.
'fight for theatre' is the first definition.
'box' can be an answer for 'fight' (boxing is a kind of fighting). I am unsure of the 'for theatre' bit.
'seats?' is the second definition.
(box seat is a kind of seat)
Can you help me to learn more?
(Other definitions for box that I've seen before include "Engage in pugilism" , "Tackle defender" , "Topiary shrub" , "Punch" , "Carton" .)
