Extant. “Beowulf” is one of the most thoroughly-studied works of literature in the world, but we’re missing large pieces of it. You see, over the course of a thousand years, almost every copy was lost or destroyed. In the 1720s, only one complete manuscript survived. Or, still existed. Or, was extant. And what did the British government do with this one-of-a-kind masterpiece? They stored it in a house with the unfortunate name, Ashburnham. One guess what happened to it then. Extant: currently in existence.
