Antigone's form of denial (8)

I believe the answer is:

negation

'denial' is the definition.
(negation is a kind of denial)

'antigone's form' is the wordplay.
'form' is an anagram indicator.
'antigone' is an anagram of 'NEGATION'.

'of' acts as a link.

(Other definitions for negation that I've seen before include "Contradiction" , "Making denial" , "Refutation by Antigone" , "One giant turns out to be a denial" , "opposite" .)

I've seen this clue in The Guardian and The Telegraph.
