See some gorilla, hunched over in large room (4)
I believe the answer is:
hall
'large room' is the definition.
(a hall is a large room)
'see some gorilla hunched over' is the wordplay.
'see some' indicates the answer is hidden within the clue (some parts of the word are used).
'over' says the letters should be written backwards.
'llah' is hidden in the letters of 'gorilla hunched'.
'llah' back-to-front is 'HALL'.
'in' is the link.
(Other definitions for hall that I've seen before include "Large country house" , "See 1" , "Large meeting room" , "Large public building" , "See 21" .)
