Cast wanting seat for Lear in the audience? (6)
I believe the answer is:
thrown
'cast' is the definition.
(cast can mean to throw)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for thrown that I've seen before include "baffled" , "Tossed" , "Confused; chucked" , "given up intentionally" , "Having been projected through the air" .)
