Etymology: The word is a plain combination of three parts. "Un-" is the old English prefix meaning "not," and "-able" comes from Latin "-abilis" through Old French, meaning "capable of being." The stem is "wedge," which comes from Old English "wecg," the name of the simple tool that splits or holds things apart by being driven into a gap. The verb "to wedge," meaning to force something into a tight space, was formed from that noun, so the adjective describes something too tightly fitted, or too firmly placed, to be forced into a space at all.
