SLIP NOOSE
A knot with a loop that closes down in size by pulling on the standing
part; it can usually be completely untied by pulling the standing part all
the way through.

SNUG
To take the slack out of a knot and tighten it.

SPILL

When a knot capsizes, loosens, or unties, either by accident or on
purpose.

SPLICE
To fasten a rope to itself or another rope by interweaving the strands.

STANDING PART
Any part of the rope other than the running end that is not being used as
a bight; it does not take part in forming the knot, but only takes strain.

STOPPER KNOT
Also called a “terminal knot,” a type of knot tied at the end of a rope,
usually for the purpose of preventing the rope from unreeving from

something or to provide a better handhold.

STRAIN
Also called “tension,” strain is the result of the rope performing the basic
job that it does, transferring force.

STRAND
A small single cord, or the largest components of a rope.

STRENGTH
The amount of strain or tension that a rope can safely handle, or the
amount it can take before breaking. When referring to a knot, it is how
much that particular knot weakens a particular cordage when tied in it.

STRETCH
The property of rope to become longer under strain.
