Etymology: "Obsoletus" is the past participle of the Latin verb "obsolescere," meaning "to fall into disuse" or "to grow out of use." That verb combined "ob-" (toward, against) with "solescere," an inceptive form of "solere," "to be accustomed." So the original sense was closer to "gone out of the habit of being used" than to "replaced by something better." The Romans used the participle in this literal, everyday way for things that had simply fallen out of custom. English borrowed the adjective "obsolete" in the early 1600s, and it kept that older flavor of gradual disuse for a while. The more technical sense, of a machine or method displaced by a newer one, developed later, especially as industrial and technological change accelerated in the 19th and 20th centuries. The modern "obsolete" describes an object's functional status, while the Latin root describes a habit quietly dying out.
