Why this word is great
PERDURATION — [Noun] The act or state of enduring persistently over time. From Latin perdūrātiō, from perdūrō ("to endure throughout") + -iō (noun-forming suffix). Unlike "perdurability" (which suggests an inherent, almost abstract capacity to last) or "duration" (a neutral measure of time's passage), perduration is the quiet, stubborn fact of continuance itself. It is the slow erosion of a river carving its bed deeper over centuries, the unbroken hum of a refrigerator in an empty house, or the way grief lingers long after the world expects it to fade—not as a virtue, nor a flaw, but simply as the weight of existence pressing onward.
