indubitably

Beyond all doubt

Indubitably means without doubt or unquestionably—an emphatic way of saying certainly or definitely.

The word sounds formal or old-fashioned, often used for comic effect or playful emphasis: Indubitably, my dear Watson.

In straightforward contexts, it simply affirms something beyond question: The evidence indubitably proves his innocence.
