v.intr.

To form a knot or knots.
To become snarled or entangled.

[Middle English, from Old English cnotta.]

USAGE NOTE In nautical usage knot is a unit of speed, not of distance, and has a built-in meaning of "per hour." Therefore, a ship would strictly be said to travel at ten knots (not ten knots per hour).

knot² (nŏt) pronunciation

n.
Either of two migratory sandpipers (Calidris canutus or C. tenuirostris) that breed in Arctic regions.

[Middle English, of Scandinavian origin.]

length See below.

speed 1 nautical mile per hour.

Internat 1955 1.852 km·h^-1 (0.514 4~ m·s^-1, 1.687 8~ ft s^-1, 1.1508~ m.p.h.). The 1978 decision of the CIPM considering it acceptable to continue to use the knot with the SI still stands.

UK To 1975, 6 080 ft·h^-1 (1.853 2 km·h^-1, 0.514 77~ m·s^-1, 1.151 5~ m.p.h.).

USA To 1954, 6 080.2 ft·h^-1 (1.853 2 km·h^-1, 0.514 79~ m·s^-1, 1.151 6~ m.p.h.).

The term relates to knotted markers at regular intervals on the log line, this being drawn out from a ship's stern by a float that would effectively stay fixed (relative to the sea rather than earthly position, hence measuring speed relative to the surface currents rather than the map). It was common in earlier times to have a sand-glass of appropriate duration against which to count the knots being drawn out, e.g. a 28-second timer and knots tied at nearly 4 fathoms spacing (correctly 3.985 2~ fathom, 14.41~ m, 47.29~ ft) would give a direct result in knots. As a unit of length, the term knot applies to this distance. (However, confusion sometimes results in the term being used to mean the nautical mile, with the speed expressed in knots per hour; such usage is grossly erroneous.)

Examples of common knots. (credit: © Merriam-Webster Inc.)

In cording, the interlacement of parts of one or more ropes, cords, or other pliable materials, commonly used to bind objects together. Knots have existed from the time humans first used vines and cordlike fibers to bind stone heads to wood in primitive axes, and were also used in the making of nets and traps. Knot making became sophisticated when it began to be used in the ropes, or rigging, that controlled the sails of early sailing vessels, and thus became the province of sailors. Knots are still depended on by campers and hikers, mountaineers, fishermen, and weavers, among others.

English Folklore: knots

Top

Have long figured in magic. It was widely held that by tying three (or nine) knots on a lace or thread, witches could render a man impotent; according to the astrologer Simon Forman early in the 17th century, this was done during the wedding ceremony itself, with the words ‘Whom God hath joined together let the Devil separate; sara till these knots be undone’. Similarly, as told in the ballad ‘Willie's Lady’, a witch might prevent a woman in labour from giving birth by secretly knotting her hair ribbons (Opie and Tatem, 1989: 220-1; F. J. Child, English and Scottish Ballads, no. 6). It was believed witches would ‘sell the wind’ to sailors in a cord with three knots; untying the first would bring a fine breeze, the second a high wind, the third a destructive storm; this is usually told of witches abroad—in Scandinavia, Scotland, the Isle of Man, or Ireland—rather than in home ports (Opie and Tatem, 1989: 446-7).

Knotting one's garter was a relatively simple form of divination, which unlike most could be practised on any night of the year, to reveal one's destined partner in a dream. Aubrey's recipe is to tie one's left garter to one's right stocking and recite the following verses, making a further knot at each comma: ‘This knot I knit, To know the thing, I know not yet, That I may see, The man (woman) that shall my husband (wife) be, How he goes, And what he wears, And what he does, all days, and years’ (Aubrey, 1696: 131-2). Knotted threads were also used as cures for whooping cough, sprains, nosebleed, and warts; in the first three cases they were worn by the patient, but for the last they were touched to each wart and then thrown away to decay (Opie and Tatem, 1989: 221-4).

Architecture: knot

1. In medieval architecture, a bunch of leaves, flowers, or similar ornament, as the bosses at the intersections of ribs, and bunches of foliage in capitals.
2. An ornamental design resembling cords which are interlaced.
3. The hard, cross-grained mass of wood formed in a trunk at the place where a branch joins the trunk.
4. In fabric construction, the presence of an imperfection that will cause a surface irregularity.

Psychoanalysis: Knot

Top

Jacques Lacan used a topological structure of the knot to define the relationship of the symbolic, the real, and the imaginary.

In particular, he referred to the structure of rings on the coat of arms of the Borromei family. After introducing this notion on February 9, 1972, in his seminar ". . . ou pire" (. . . or worse), he made the knot a central focus of his theory.

In mathematical terms, a knot is a simple closed curve (Jordan's curve). Lacan mainly considered two nodal structures (Figure 1):

The Borromean Knot: three component loops joined together in such a way that when one loop is cut the other two are no longer connected;
The clover-leaf knot: the three components have been connected together into a single continuous loop.

For Lacan, the knot symbolizes the Imaginary. As an imaginary construct, it gives consistency to the symbolic. Taken symbolically, the knot represents the undecidability of the real or imaginary.

The knot is an object located in space. A two-dimensional representation of it is made by means of crossings over or under. The knot's structure is determined by what crosses over or under what. However, the knot's structure is not dependent on its representation. Indeed, it was to translate representation into structure that an algebraic writing system for knots was developed. This writing system was refined over the course of the twentieth century and gradually made it possible to distinguish among different types of knots. In this system, the knot's topological loops become letters (in the form of polynomials). This marks the fact that the knot originates in the lost letter.

In Lacan's spoken lectures, the knot functioned first and foremost as a piece of writing. This called into question of the relationship between speech and writing, and showed that "writeability" is essential to the formation of the unconscious (Sigmund Freud's "Letter 52" to Wilhelm Fliess). "The unconscious can only be expressed in knots of language" (Lacan).

IN BRIEF: A fastening made by tying together lengths of material, such as rope, in a prescribed way.

He learned to tie twenty knots for his scout badge.

Tutor's tip: If "not" (an expression of negation) for the "knot" (a fastening that binds together rope or chord, etc.) the rope would have broke and our efforts been naught.

Dream Symbol: Knot

Top

A knot is an obvious symbol of constraints and restrictions on one's freedom of thought, feelings, or actions, indicating a difficult situation that needs to be untied. Anxieties about getting married ("tying the knot") are sometimes denoted by this dream symbol. More positively, a knot can symbolize control, and having something "all wrapped up." (See also Necktie).

Some knots: 1. Splice 2. Manrope knot 3. Granny knot 4. Rosebud stopper knot(?) 5. Matthew Walker's knot 6. Shroud knot 7. Turks head knot 8. Overhand knot, Figure-of-eight knot 9. Reef knot or Square knot 10. Two half hitches (see round turn and two half hitches)

A knot is a method for fastening or securing linear material such as rope by tying or interweaving. It may consist of a length of one or more segments of rope, string, webbing, twine, strap, or even chain interwoven such that the line can bind to itself or to some other object—the "load". Knots have been the subject of interest for their ancient origins, their common uses, and the area of mathematics known as knot theory.

Usage

There is a large variety of knots, each with properties that make it suitable for a range of tasks. Some knots are used to attach the rope (or other knotting material) to other objects such as another rope, cleat, ring, or stake. Some knots are used to bind or constrict objects. Decorative knots usually bind to themselves to produce attractive patterns. The ability to choose the right knot for the job is a core skill of knot-tying. However, if memory is limited, three of the most useful knots are the bowline, the sheet bend, and the clove hitch.^[1]

Learning

Sailors learning knots and ropework in the early 20th century

The number of books, websites, videos, and other resources about knots attests to their interest and value. While some people can look at diagrams or photos and tie the illustrated knots, others learn best by being shown. Knot tying skills are often transmitted by sailors, scouts, climbers, cavers, arborists, rescue professionals, fishermen, and surgeons. After one has mastered a few basic knots, diagrams and pictures become easier to interpret. As one learns more knots, one starts to discern patterns in their structure and tying method. Learning knots demands practice and patience.

Applications

Knots are essential in many industries, hobbies and domestic activities. Even simple activities such as running a load from the hardware store to home can turn into disaster if a clumsy twist in a cord passes for a knot. Truckers in need of securing a load may use a trucker's hitch, gaining mechanical advantage. Knots can save a spelunker from finding himself buried under rock. Learning well-tested knots prior to engaging in hazardous activities such as sailing or rock-climbing is a critical safety measure.

Knots can be applied in combination to produce complex objects such as lanyards and netting. In ropework, the frayed end of a rope is held together by a type of knot called a whipping knot. Many types of textiles use knots to repair damage. Macrame, one kind of textile, is generated exclusively through the use of knotting, instead of knits, crochets, weaves or felting. Macramé can produce self-supporting three dimensional textile structures, as well as flat work, and is often used ornamentally or decoratively.

Properties

Strength

Knots invariably weaken the rope in which they are made. When knotted rope is strained to its breaking point, it almost always fails at the knot or close to it, unless it is defective or damaged elsewhere. The bending, crushing, and chafing forces that hold a knot in place also unevenly stress rope fibers and ultimately lead to a reduction in strength. The exact mechanisms that cause the weakening and failure are complex and are the subject of continuous study.

"Relative knot strength," also called knot efficiency, is the breaking strength of a knotted rope in proportion to the breaking strength of the rope without the knot. Determining this number is hard because many factors can affect a knot efficiency test: the type of fiber, the style of rope, the size of rope, whether it is wet or dry, how the knot is dressed before loading, how fast the knot is loaded, whether the knot is repeatedly loaded, and so on. Most common knots' efficiency range between forty and eighty percent.

While some rope splices can nearly maintain the rope's full strength, in most situations, when forming loops and bends conventional knots are far more practical. Thus the prudent knot user will always allow for a large safety margin in the strength of rope chosen for a task due to the weakening effects of knots, aging, damage, shock loading, etc. In general, the safe working load is often specified as between 10% and 20% of the rated breaking strength of the rope being used.[1] For life-threatening applications, many other factors come into play which are beyond the current scope of this article. Experienced practitioners should always be consulted before using ropes and knots when safety of life, limb, or property is involved.

Security

Even if the rope does not break, a knot may still fail to hold. Knots that hold firm under a variety of adverse conditions are said to be more secure than those that do not. The main ways knots fail to hold are:

Slipping

The load creates tension that pulls the rope back through the knot in the direction of the load. If this continues far enough, the working end passes into the knot and the knot unravels and fails. This behavior can worsen when the knot is repeatedly strained and let slack, dragged over rough terrain, or repeatedly struck against hard objects such as a masts and flagpoles.

Even with secure knots, some slippage may take place as the knot is first put under real tension. This risk can be mitigated by leaving plenty of rope at the working end outside of the knot, and by dressing the knot cleanly and tightening it as fully as possible before loading. Sometimes, the use of a stopper knot or, even better, a backup knot can prevent the working end from passing through the knot; but if a knot is observed to slip, it is generally preferable to use a more secure knot. In life critical uses, backup knots are often added to already secure knots in order to maximize safety.

Capsizing

Capsizing (or spilling) a knot refers to changing a knot's form and rearranging its parts, usually by pulling on specific ends in certain ways. When used inappropriately, some knots tend to capsize easily or even spontaneously. Often the capsized form of the knot offers little resistance to slipping or unraveling. For an excellent example of a knot that capsizes dangerously, see the discussion of the reef knot used as a bend.

Sometimes a knot is intentionally capsized as a method of tying another knot, as with the "lightning method" of tying a Bowline. Some knots, such as the Carrick Bend, are generally tied in one form then capsized to obtain a stronger or more stable form.

Sliding

In knots that are meant to grip other objects, failure can be defined as the knot moving relative to the object being gripped. While the knot itself does not fail, it ceases to perform the desired function. For instance, a simple Rolling Hitch tied around a railing and pulled parallel to the railing might hold up to a certain tension, then start sliding. Sometimes this problem can be corrected by working-up the knot tighter before subjecting it to load, but usually the problem requires either a knot with more wraps or a rope of different diameter or material.

Components

Knot components

A: Turn
B: Round turn
C: Two round turns

Bight

Main article: Bight (knot)

The center part of a length of rope, string, or yarn—in opposition to the rope's ends.

A "bight" is any curved section, slack part, or loop between the ends of a rope.
The phrase "in the bight" implies that a U-shaped section of rope is used in making a knot. Many knots can be tied either with the end or in the bight.

Bitter end

More a ropeworker's term than a knot term, it refers to the end of a rope that is tied off, hence the expression "hanging onto the bitter end". A bitt is a metal block with a crosspin used for tying lines to, found on docks. In fact the bitter end is the end of the Anchor "Cable" that connects to the Anchor Bitts in the cable locker under the forecastle or poop using the bitter pin. (British nautical usage). Other uses may be borrowed from this derivation.

Loop

A full circle formed by passing the working end over itself. Note that the term 'loop' is also used to refer to a category of knots (see 'Categories' below).

Elbow

Two crossing points created by an extra twist in a loop.

Standing end

The end of the rope not involved in making the knot, often shown as unfinished.

Standing part

Section of line between knot and the standing end (see above).

Turn

Main article: Turn (knot)

A turn or single turn is a single pass behind or through an object.
A round turn is the complete encirclement of an object; requires two passes.
Two round turns circles the object twice; requires three passes.

Working end

The active end of a line used in making the knot. May also be called the 'running end' or 'live end'.

Working part

Section of line between knot and the working end.

Knot theory

A trefoil knot a mathematical version of an overhand knot.

Knot theory is a branch of topology. It deals with the mathematical analysis of knots, their structure and properties, and with the relationships between different knots. In topology, a knot is a figure consisting of a single loop, abstracted from any physical rope or line, with any number of crossing or "knotted" elements. As such, it has no proper ends, and cannot be undone or untied. Various mathematical techniques are used to classify and distinguish knots. For instance, the Alexander polynomial can be used to distinguish the trefoil knot from the figure-of-eight knot and the unknot (a simple loop).
