Condescend to quote Hamlet, for instance (5)
I believe the answer is:
deign
'condescend' is the definition.
(synonyms)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for deign that I've seen before include "Think fit" , "See fit" , "consent" , "Think appropriate" , "Be pleased" .)
