Question

What's the difference between "undoubtedly" and "no doubt"?

Accepted Answer

You add "no doubt" to a statement to say that you are assuming that something is true, although you cannot really be certain about it ("As Jennifer has no doubt told you, we are leaving tomorrow"). You can use "undoubtedly" to emphasize that something exists or is true ("Undoubtedly, this is the best method to adopt.")
