Silly negation makes daughter doomed (8)
I believe the answer is:
antigone
'daughter doomed' is the definition.
I can't judge whether this definition defines the answer.
'silly negation' is the wordplay.
'silly' is an anagram indicator.
'negation' is an anagram of 'ANTIGONE'.
'makes' acts as a link.
Can you help me to learn more?
(Other definitions for antigone that I've seen before include "The Burial at Thebes is Heaney's translation of Sophocle's (8)" , "Jocasta's daughter" , "Make drama" , "Tragedy by Sophocles" , "Greek drama" .)
