- Further information: List of knot terminology
The list of knots is extensive, but common properties allow for a useful system of categorization. For example, loop knots share the attribute of having some kind of an anchor point constructed on the standing end (such as a loop or overhand knot) into which the working end is easily hitched to using a round turn. An example of this is the bowline. Constricting knots often rely on friction to cinch down tight on loose bundles; an example is the Miller's knot. Knots may belong to more than one category.
- Bend
- A knot uniting two lines (for knots joining two ends of the same line, see binding knots or loops). List of bends.
- Binding
- A knot that restricts object(s) by making multiple winds. List of binding knots.
- Coil
- Knots used to tie up lines for storage. Another handy coil is here.
- Decorative knot
- A complex knot exhibiting repeating patterns often constructed around and enhancing an object. List of decorative knots.
- Hitch
- A knot tied to a post, cable, ring, or spar. List of hitch knots.
- Lashing
- A knot used to hold (usually) poles together. List of lashing knots.
- Loop
- A knot used to create a closed circle in a line. List of loop knots.
- Plait (or braid)
- A number of lines interwoven in a simple regular pattern. List of plait knots.
- Slip (or running)
- A knot tied with a hitch around one of its parts. In contrast, a loop is closed with a bend. While a slip knot can be closed, a loop remains the same size. List of slip knots.
- Slipped
- Some knots may be finished by passing a bight rather than the end, for ease of untying. The common shoelace knot is an example, being a reef knot with both ends slipped.
- Seizing
- A knot used to hold two lines or two parts of the same line together. List of seizing knots.
- Sennit
- A number of lines interwoven in a complex pattern. See also Chain sinnet.
- Splice
- A knot formed by interweaving strands of rope rather than whole lines. More time-consuming but usually stronger than simple knots. List of splices.
- Stopper
- A knot tied to hold a line through a hole.
- Trick
- A knot that is used as part of a magic trick, a joke, or a puzzle. List of trick knots.
- Whipping
- A binding knot used to prevent another line from fraying.

Famous quotes containing the word categories:
“all the categories which we employ to describe conscious mental acts, such as ideas, purposes, resolutions, and so on, can be applied to ... these latent states.”
—Sigmund Freud (1856–1939)
“Of course I’m a black writer.... I’m not just a black writer, but categories like black writer, woman writer and Latin American writer aren’t marginal anymore. We have to acknowledge that the thing we call “literature” is more pluralistic now, just as society ought to be. The melting pot never worked. We ought to be able to accept on equal terms everybody from the Hassidim to Walter Lippmann, from the Rastafarians to Ralph Bunche.”
—Toni Morrison (b. 1931)
“All cultural change reduces itself to a difference of categories. All revolutions, whether in the sciences or world history, occur merely because spirit has changed its categories in order to understand and examine what belongs to it, in order to possess and grasp itself in a truer, deeper, more intimate and unified manner.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
