doubtless
UK: ˈdaʊtləs | US: ˈdaʊtləs
adj. without doubt; certain or sure
adv. undoubtedly; without question
The word "doubtless" combines "doubt," derived from Old French douter (to fear, hesitate), itself from Latin dubitare (to waver), with the suffix "-less," meaning "without" (from Old English -lēas). The fusion creates a term that literally means "without doubt," reflecting certainty or confidence. Over time, it evolved into both an adjective and adverb, emphasizing unquestionable truth or inevitability.
She was doubtless the best candidate for the job.
The project will doubtless face challenges, but the team is prepared.
His dedication to the cause is doubtless admirable.
Doubtless, the weather will improve by tomorrow.
They were doubtless relieved when the results came in.
