A Noose Tightens Because of How It Is Tied
A noose is a loop that tightens when pulled. The knot is a running knot, and the same principle appears in the lasso.
A noose is a loop of rope that tightens as it is pulled. The mechanism is in the knot: a *running knot* has the standing part of the rope passing through a fixed eye, so tension shortens the loop rather than the rope. The same principle makes a lasso work and a slip knot fail. The word probably comes from Latin *nodus*, a knot, through Provençal, though the route is uncertain.
- A tightening loop. *A noose of rope.*
- A running knot. *Tied with a running knot.*
- Lasso — the same principle. *A lasso.*
- Slipknot — unties when pulled. *A slipknot.*
- Latin — *nodus*, a knot. *The likely source.*

Knots that slide and knots that hold
- Running knot — the loop tightens as tension increases
- Bowline — forms a fixed loop that will not slip
- Slipknot — designed to release with one pull
- Clove hitch — grips a post but can roll under load
- The difference is whether the rope can run through the eye
Middle English *nose*, probably from Old French *nous*, from Latin *nodus*, a knot, though the route is disputed.
Why does a noose tighten?
Because the rope runs freely through a fixed eye, so pulling shortens the loop instead of the rope.
Is a bowline a noose?
No. A bowline makes a fixed loop that does not tighten under load, which is why it is used for rescue.
