Etymology 1

From Middle English knotte, from Old English cnotta, from Proto-Germanic *knuttô, *knudô (“knot”); (cognate with Old High German knoto (German Knoten, Dutch knot, Low German Knütte); compare also Old Norse knútr > Danish knude, Swedish knut, Norwegian knute, Faroese knútur, Icelandic hnútur). Probably ultimately from Proto-Indo-European *gnod- (“to bind”), compare Latin n?dus and its Romance descendants. Doublet of node.

Noun

knot (plural knots)

1. A looping of a piece of string or of any other long, flexible material that cannot be untangled without passing one or both ends of the material through its loops.

   Climbers must make sure that all knots are both secure and of types that will not weaken the rope.

2. (of hair, etc) A tangled clump.

   The nurse was brushing knots from the protesting child's hair.

3. A maze-like pattern.
4. (mathematics) A non-self-intersecting closed curve in (e.g., three-dimensional) space that is an abstraction of a knot (in sense 1 above).

   A knot can be defined as a non-self-intersecting broken line whose endpoints coincide: when such a knot is constrained to lie in a plane, then it is simply a polygon.

       A knot in its original sense can be modeled as a mathematical knot (or link) as follows: if the knot is made with a single piece of rope, then abstract the shape of that rope and then extend the working end to merge it with the standing end, yielding a mathematical knot. If the knot is attached to a metal ring, then that metal ring can be modeled as a trivial knot and the pair of knots become a link. If more than one mathematical knot (or link) can be thus obtained, then the simplest one (avoiding detours) is probably the one which one would want.

5. A difficult situation.

   I got into a knot when I inadvertently insulted a policeman.

   • 1664, Robert South, A Sermon Preached Before the University at Christ-Church, Oxon

     A man shall be perplexed with knots, and problems of business, and contrary affairs.

6. The whorl left in lumber by the base of a branch growing out of the tree's trunk.

   When preparing to tell stories at a campfire, I like to set aside a pile of pine logs with lots of knots, since they burn brighter and make dramatic pops and cracks.

7. Local swelling in a tissue area, especially skin, often due to injury.

   Jeremy had a knot on his head where he had bumped it on the bedframe.

8. A tightened and contracted part of a muscle that feels like a hard lump under the skin.
9. A protuberant joint in a plant.
10. Any knob, lump, swelling, or protuberance.
    • ?, Alfred Tennyson, Lancelot and Elaine

      The pair cannot separate until the knot has subsided – anywhere from twenty minutes to hours, depending on the fic.

    • 2017, Marianne Gunderson, "What is an omega? Rewriting sex and gender in omegaverse fanfiction", thesis submitted to the University of Oslo, page 89:
