undoubtedly
UK: ʌnˈdaʊtɪdli | US: ʌnˈdaʊtɪdli
adv. without doubt; certainly
adv. used to emphasize the truth of a statement
The word "undoubtedly" is built from the root "doubt," which originates from the Latin "dubitare" (to hesitate or waver). The prefix "un-" negates the root, turning "doubt" into "undoubted" (free from uncertainty). The suffix "-ed" forms the adjective, and "-ly" converts it into an adverb. The progression reflects a logical reinforcement of certainty: from hesitation ("doubt") to its negation ("undoubted") and finally to an adverbial form emphasizing absolute assurance ("undoubtedly").
