In knot tying, a bight is a curved section, slack part, or loop between the two ends of a rope, string, or yarn. An important concept, the term is used extensively in the description of knots and the discourse of knotting and related subjects. The term is also used in a more specific way when describing Turk's head knots, indicating how many repetitions of braiding are made in the circuit of a given knot. A familiar practical use of a bight is finishing a knot by passing a bight, rather than the end, to make a slipped knot (also slipped loop and quick release knot). This slipped form of the knot is more easily untied. The traditional bow knot used for tying shoelaces is simply a reef knot with the final overhand knot made with two bights instead of the ends. Similarly, a slippery hitch is a slipped clove hitch.
