To return a greeting from a Shakespearean play (7)
I believe the answer is:
othello
'a shakespearean play' is the definition.
(I've seen this in another clue)
'to return a greeting' is the wordplay.
'return' is a reversal indicator.
'a greeting' becomes 'hello' (hello is a kind of greeting).
'to' back-to-front is 'ot'.
'ot'+'hello'='OTHELLO'
'from' is the link.
(Other definitions for othello that I've seen before include "He murdered his wife Desdemona" , "drama!" , "Moorish gentleman" , "He killed his wife Desdemona" , "As part" .)
