Etymology: "Trustable" is simply "trust" with the suffix "-able" attached, the same ending found in words like "washable" or "readable". The suffix comes from Latin "-abilis", meaning "able to be" or "capable of being", and English has long used it to turn verbs into adjectives describing what can be done to something or what it is capable of. The base word "trust" is older and has a Norse-influenced history in English, but "trustable" is a straightforward combination rather than a borrowing or a coinage with a famous backstory. Its sense is close to "trustworthy" and "reliable", though it is a little more informal, and some usage guides have long regarded it as a less established alternative to those words.
