To deny or refuse to acknowledge something; to reject or negate.
From Latin 'denegare' (de- 'away' + negare 'to deny'), formed in the 16th century as an intensified form of 'negate' meaning to actively refuse or deny.
This word is so rare that most spell-checkers don't recognize it, yet it's the perfect term for when you don't just disagree—you actively, emphatically refuse to accept something.
