Surface Forms

first quarter singular

Morphology

first + quarter

The meaning is directly compositional: 'first' (initial) + 'quarter' (one fourth) yields the initial one-fourth phase of a cycle, so a learner who knows both words and the context ('of the Moon') can infer it refers to the lunar phase after the new moon. This numeric/fractional construction is common across languages and follows ordinary English composition patterns, making it readily comprehensible to a B1 learner.

Etymology

First quarter comes from watching the Moon: when the Moon has moved about a quarter of the way around Earth it looks 'half' lit in the sky. So the name refers to that 'stage' of the Moon and is used today to mean that point in the Moon's cycle.
