Morphology

north + star

The compound 'North Star' is directly compositional: 'north' (a cardinal direction) + 'star' (a celestial object) yields the predictable referent 'the star toward the north' — i.e., the star used for navigation (Polaris). Although it's a conventionalized proper name, the meaning follows straightforward logic and has clear cross-linguistic parallels, so a B1 learner who knows the constituents would readily infer its meaning.

Etymology

North Star is the bright star people used to find 'north' at night because it sits almost still in the sky above Earth's north pole. That's why it became a natural 'guide' and a reliable point to help people find direction.
