Imagine a medieval thinker staring at a footprint in mud and saying, in effect, “Here is something clear enough to make an inference.” That is the original force of *evidence*: not yet courtroom paperwork, but an appearance that lets the mind see what is otherwise hidden. Around 1300, English borrowed the word through Old French from Late Latin *evidentia*, which meant “clearness” and then “proof”; its Latin source, *evidens*, meant “obvious” or “apparent.” The legal sense arrived around 1500 and gradually pushed aside the older word *witness* for material or testimony presented to establish a fact. The family resemblance to *video* and *vision* is no accident: *evidence* is what makes an unseen conclusion visible to the mind. Tomorrow, remember it as intellectual light—not certainty itself, but whatever lets you see why certainty might be reasonable.
