Etymology: "Unknottable" is a plain English construction: the prefix "un-" meaning "not" or "the reverse of" attached to "knottable," which is itself "unknot" plus the suffix "-able," meaning "capable of being." So the word literally describes something that cannot be untied, and its sense of an unresolvable problem grows naturally out of the physical image of a knot that won't come loose. The verb "unknot" is the older building block here. "Knot" has been in English since Old English, and the "un-" prefix has been used to reverse actions on physical things, like "untie" or "unlock," for centuries. Adding "-able" to a verb produces an adjective meaning "able to be" the action, so "unknottable" is built in the same pattern as words like "breakable" or "washable," with the double negative effect of "un-" and "-able" working in opposite directions.
