Etymology

the word "incredulously" is built upon the latin verb credere, meaning "to believe, trust, or entrust," which is also the source of core english words like "credit" and "creed." the latin adjective credulus (believing) was combined with the negative prefix in- to form incredulus, meaning "unbelieving." this passed into english as "incredulous." the modern adverb "incredulously" was then formed by adding the adverbial suffix -ly to the adjective, creating a word that literally describes the manner of one who is "not believing." the semantic journey is direct, from the concrete act of placing trust to the abstract state of withholding belief, often expressed through tone or gesture.
