believable
UK: bɪˈliːvəbl | US: bɪˈliːvəbl
adj. capable of being believed; credible or plausible.
The word "believable" combines the verb "believe," derived from Old English "belēfan" (to trust, have faith in), with the suffix "-able," from Latin "-abilis," indicating capacity or worthiness. The fusion reflects a logical progression: something that can ("-able") be trusted or accepted as true ("believe"). This construction follows a common pattern in English for forming adjectives that describe potential or feasibility (e.g., "readable," "manageable").
