no doubt
Without a question
No doubt expresses certainty or strong likelihood about something: No doubt she'll arrive late, as usual.
It can acknowledge what seems obvious: He was, no doubt, the best candidate.
The phrase sometimes carries a hint of resignation or concession—admitting something is probably true even if unwelcome.
In casual speech, no doubt often serves as simple agreement or affirmation: Are you coming tonight? No doubt.
