Giant swivelling seat in corner (7)
I believe the answer is:
goliath
'giant' is the definition.
(giant in the bible)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for goliath that I've seen before include "Biblical giant" , "Giant Philistine killed by David" , "Giant Philistine felled by David" , "David slew him with a slingshot (7)" , "I got Hal a giant form the bible" .)
