Etymology: "Unabraded" is simply the negative form of "abraded," with the prefix "un-" (meaning "not") attached to it. "Abraded" itself comes from the Latin verb "abradere," built from "ab-" ("off, away") and "radere" ("to scrape"), so the core idea is scraping something away from a surface. Abrasion has been part of English for centuries, and the word carries that sense of surface material being worn or scraped off. Because "un-" is one of English's most productive prefixes, it can attach to a participle like "abraded" without any special history. The result describes a surface or object that has kept its original state, with nothing scraped or rubbed away. The word is typically used in technical, geological, or medical contexts, where it signals that a surface, rock, or tissue is intact.
