Both a verb and a noun, tether keeps things tied together, or is the tie itself. Remember, when you tether that chair to those balloons, use a strong tether. You don't want to drop from the sky because you tied them together using a cheap piece of rope. Think of the childhood game tether-ball. The ball is tethered to a pole by a tether.
