Stomachs revealed in parts of stadium (6)
I believe the answer is:
stands
'stomachs' is the definition.
('stand' can be a synonym of 'stomach')
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for stands that I've seen before include "Remains valid" , "Gets to one's feet" , "In which to sit at football matches" , "Places upright" , "Tiered seats in stadiums" .)
