Turn it back before Frank embraces Jocasta's daughter (8)
I believe the answer is:
antigone
'jocasta's daughter' is the definition.
(I've seen this before)
'turn it back before frank embraces' is the wordplay.
'turn' becomes 'go' (a person's move in a board game).
'back' says the letters should be written in reverse.
'before' says to put letters next to each other.
'frank' becomes 'Anne' (Anne Frank, Holocaust victim).
'embraces' indicates putting letters inside.
'it' backwards is 'ti'.
'go' put after 'ti' is 'tigo'.
'tigo' placed within 'anne' is 'ANTIGONE'.
(Other definitions for antigone that I've seen before include "classical play" , "Jocasta's daughter" , "The Burial at Thebes is Heaney's translation of Sophocle's (8)" , "Tragedy by Sophocles" , "Greek play" .)
