Etymology: "Trustability" is a plain formation: the noun "trust" with the suffix "-ability" attached. That suffix comes from Latin "-abilis," meaning "able to be," and English has used it for centuries to build adjectives like "readability" and "dependability." Attaching it to "trust" yields a word meaning the quality of being able to be trusted. The word's main interest lies in its place within that family. "Trustworthy" and "trustful" are older and more common, and "trustability" is a comparatively recent, less standard coinage that sounds more technical, which is why it appears in discussions of systems and institutions as often as of people. The suffix does most of the work: it turns a feeling of confidence into a measurable property that can be rated or assessed.
