The term "ratline" finds its origin in nautical terminology, specifically in sailing. Ratlines are tied horizontally between the shrouds and serve as steps or rungs on the rigging of larger sailing vessels, such as schooners and square-riggers. These small ropes create a ladder-like structure, offering sailors a means to access higher points on the mast or to navigate across the rigging safely. The ratlines are secured to the shrouds by various knots or lashings, providing stability and support to the rigging.
Apart from their functional purpose, ratlines can also be used as markers to indicate certain heights on the rigging during navigation, maintenance, or repair on the ship. They can also be utilized as reference points for adjusting sails or measuring distances while sailing.
In a broader sense, the term "ratline" may be metaphorically used to describe any series of steps or levels in a hierarchy or organization.

The word "ratline" comes from the nautical terms "rat" and "line". "Rat" originated from the Old English word "raet", meaning "rat". In maritime jargon, "rat" refers to a rope or cord that is twisted, gnarled, or tangled. "Line" is a common nautical term for a rope, cord, or cable. The "ratline" specifically refers to a series of small ropes or cords that stretch horizontally between the shrouds on a sailing ship, providing footholds for sailors to climb up and down the rigging. The term "ratline" has been in use since the early 19th century and is derived from its characteristic appearance resembling the tangled or gnarled tail of a rat.
