UK: ˌʌn.dɪˈnaɪ.ə.bli | US: ˌʌn.dɪˈnaɪ.ə.bli
adv. in a way that cannot be denied or disputed
adv. unquestionably; without doubt
The word "undeniably" is built from the prefix un- (meaning "not"), the root deny (from Latin denegare, "to refuse"), and the suffix -able (indicating capability). The addition of -ly converts the adjective "undeniable" into an adverb. The term evolved through Middle English from Old French denier, retaining its core meaning of refusal or contradiction, but with un- and -able adding layers of negation and potentiality. The adverb form emphasizes an irrefutable quality.
Her talent is undeniably exceptional.
The evidence proves his guilt undeniably.
This is undeniably the best solution to the problem.
The view from the summit is undeniably breathtaking.
He was undeniably the leader of the group.
