Morphology

new + moon

The compound is largely compositional — 'new' + 'moon' yields the idea of a moon that is newly appearing, and many languages use an equivalent term (e.g. Spanish 'luna nueva'), so a learner can get a basic sense from the constituents. However, the precise astronomical sense (the specific phase timing and visibility conditions) is conventional and somewhat technical, so a B1 learner who only knows the words may not derive the full, specialised meaning without exposure.

Etymology

The noun new moon names the moment when a thin bright crescent of the moon appears after the moon has been hidden. People called it new because it looks like the Moon is 'starting' again, so today new moon means the first visible crescent or the time it appears.
