undisputably
Without any doubt
Undisputably means without dispute or question—a variant of the more standard *indisputably*.
Both forms work the same way: He was undisputably the best player on the team.
Some consider *undisputably* nonstandard, but it appears often enough in speech and writing to be unremarkable.
