no-doubt
Without any question
No-doubt as a modifier means certain or assured, often with a hint of swagger: He had that no-doubt confidence of someone who'd never failed.
The hyphenated form appears before nouns it modifies, while the unhyphenated no doubt works as an adverb meaning certainly or probably: No doubt she'll be late again.
