Etymology: The Latin verb "abrumpere" meant "to break off," and its past participle "abruptus" described something already snapped apart. English borrowed that participle in 1583, so the adjective carries the physical picture of a rope or branch torn clean through. A sudden, jagged break is what the word originally pictured, and the sense of something unexpected came later. The word is built from "ab," meaning "from" or "away," and "rumpere," meaning "to break," the same root that gives English "rupture" and "erupt." Those relatives share the sense of something bursting or splitting apart, which is why "abrupt" still suggests a sharp, unceremonious interruption.
