Etymology: "Unknotable" is a plain English formation: the verb "unknot" (a reversal of "knot," meaning to untie) plus the suffix "-able," which means capable of being acted upon. Put together, the word describes a knot or tangle that cannot be undone. "Knot" itself comes from Old English "cnotta," and "unknot" follows the same pattern as other English verbs formed by adding "un-" to a verb meaning to reverse an action, such as "untie" or "unfasten." The suffix "-able" came into English through Old French from Latin "-abilis," and it was attached to native English stems very freely from the Middle English period onward. That freedom explains why English speakers can build a word like this on the spot whenever a knot needs describing. The formation is productive rather than traditional, so there is no single coiner or famous first use to point to.
