Origin of knotMiddle English, from Old English cnotta. Word History: In nautical usage, knot is a unit of speed, not of distance, and has a built-in meaning of “per hour.” A ship is said to travel at ten knots (and not ten knots per hour). Although the knot is defined as one nautical mile per hour, the similarity in sound between knot and nautical mile is entirely coincidental. The unit called the knot originated in a traditional method of measuring the speed of ships in use at least since the 16th century. A long rope was knotted at fixed intervals, wound on a spool, and tied to the end of a large wooden wedge, called the chip log or just log. When the log was thrown into the water, it would remain in roughly the same place where it splashed down. As the ship moved away, the rope would pay out and sailors would count the number of knots in the rope that were paid out over a fixed stretch of time, usually measured with a sand hourglass. Eventually, the calculation of speed using this method was made easier by knotting the rope at intervals of 47 feet and 3 inches and using an hourglass that ran out after 30 seconds. If one knot in the rope was paid out during this time, the ship was said to be moving at one knot, or one nautical mile per hour. Because of adjustments in the standard values of units of measurement over the years, a 28-second interval of time is now used in calculating a ship's speed using a rope in this way, but the basic principle remains the same.

Origin of knotMiddle English, of Scandinavian origin.
- 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.
- (of hair, etc) A tangled clump.
- The nurse was brushing knots from the protesting child's hair.
- A maze-like pattern.
- (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 (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 (link) can be thus obtained, then the simplest one (avoiding detours) is probably the one which one would want.

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

From Old English cnotta, from Proto-Germanic *knuttan-; (cognate with Old High German knoto (German Knoten, Dutch knot, Low German Knütte); compare also Old Norse knútr > Danish knude, Swedish knut, Norwegian knute, Icelandic hnútur). Probably ultimately from Proto-Indo-European *nod- (“to bind”), cf. Latin nodus and its Romance successors.
From the practice of counting the number of knots in the log-line (as it plays out) in a standard time. Traditionally spaced at one every 1/120th of a mile.
(plural knots or knot)
Supposed to be derived from the name of King Canute, with whom the bird was a favourite article of food. See the species epithet canutus.
