Standing end
The end of a rope that is not being used to tie; Shibari Study's glossary defines it as the part already worked into the tie, opposite the working end.
In general knot terminology the standing end is the longer end of a rope that is not involved in forming the knot, and it is often, though not always, the end that carries the load. Wikipedia calls the length between the knot and the standing end the standing part. Rope bondage glossaries differ: Rope365 groups standing end, working end and tail together as the rope not yet tied, while noting the knot-world distinction, and Shibari Study defines the standing end as the rope that has already been tied, the counterpart of the working end that is still being used. Knot descriptions such as that of the half hitch are given in terms of how the working end crosses the standing part.
