undoubted
Not in dispute
Undoubted means not questioned or disputed—accepted as genuine or certain: her undoubted talent, the undoubted leader of the movement.
The word emphasizes that something is beyond doubt, though it often appears where *undeniable* or *unquestionable* might serve equally well.
The adverb *undoubtedly* is far more common.
