High bank of seats on right entering trireme? (7)
I believe the answer is:
gallery
'high bank of seats' is the definition.
I can't tell whether this defines the answer.
'right entering trireme?' is the wordplay.
'right' becomes 'r' (common abbreviation).
'entering' is an insertion indicator.
'trireme?' becomes 'galley' (type of galley ship).
'r' put inside 'galley' is 'GALLERY'.
'on' acts as a link.
Can you help me to learn more?
(Other definitions for gallery that I've seen before include "Covered balcony" , "Place where pictures are exhibited" , "Building for works of art" , "Upper floor of theatre" , "exhibition hall" .)
