Etymology: "Mistakability" is a plain formation: the noun "mistake" with the suffix "-ability" attached, the same pattern that gives words like "readability" or "washability" from "readable" and "washable." The suffix "-ability" comes from Latin "-abilitas," itself built from "-abilis," meaning "able to be," so the whole word literally means the quality of being able to be mistaken. The base word "mistake" has an interesting origin of its own. It came into English from Old Norse "mistaka," meaning "to take in error," with the "mis-" prefix (meaning "wrongly") joined to "taka" (to take). That makes a mistake, at root, something you have wrongly taken hold of, a misapprehension.
