Morphology

nautical + linear + unit

The meaning 'a unit of distance used in navigation' is directly and compositionally derivable from 'nautical' (relating to ships/navigation) + 'linear' (pertaining to length) + 'unit' (a measure). This follows a standard noun‑phrase composition pattern found across languages, so a B1 learner who knows the constituents should be able to infer the meaning.

Etymology

Nautical linear unit comes from sailors who used simple lengths, like a ship's rope (a 'cable') or a small part of the Earth, to measure distance at sea. Here nautical means 'from the sea', linear means a straight distance and unit means a fixed measure, so the phrase now means a sea measure used for 'navigation'.
