The word "reliable" combines the verb "rely" (from Old French relier, meaning "to bind fast," derived from Latin religare—re- "back" + ligare "to bind") with the suffix "-able" (from Latin -abilis, indicating capability). Originally, "rely" implied a binding trust, and "-able" transformed it into an adjective meaning "fit to be depended upon." Over time, "reliable" evolved to emphasize consistency and trustworthiness in both objects and people.
