Etymology: "Nongrooved" is a plain formation: the prefix "non-", meaning "not", attached to "grooved," the past participle adjective of "groove." The base word goes back to Old English "groefe," a channel or trench, related to "grave" in the sense of a pit dug in the ground, and it came to mean a furrow or cut line in the late Middle Ages. The meaning of "grooved" moved from a dug channel to any surface marked with such lines, and "non-" was added to it in the usual way that English has long attached it to participles and adjectives. The "non-" prefix itself is borrowed from Latin "non," meaning "not," and it has been productive in English since the 1600s, when writers began using it freely to form negative adjectives. Words like "nongrooved" are usually technical or descriptive coinages, built on demand when a writer needs to contrast a surface with one that is carved or impressed, rather than words with a long independent history.
