ENDLESSNESS — [Noun] The state or characteristic of being without end. From Middle English endelesnesse, from Old English endelēasnes, equivalent to endless ("without end") + -ness ("state or quality"). Unlike "infinity" (a cold, abstract calculus) or "finiteness" (a cage of edges), "endlessness" is the lived weight of the unbroken horizon—the highway stretching into a heat haze, the ocean swallowing the sky, the slow unfurling of a desert that swallows footsteps as soon as they are made. It is not a concept but a condition: the terrible, beautiful fact that some things simply refuse to stop.
