Half of the Moon you cannot see because it faces away from Earth. Half of the side you could see is in darkness at "half Moon". That makes 3/4 of the Moon invisible and 1/4 visible. Hence "a quarter Moon" is visible.
Another viewpoint:
No, that's not really the answer. This is the answer:
Let's start with "New Moon". Later, at "Full Moon", the Moon is halfway through its cycle of phases.
Halfway between these two phases we see a half Moon. That's called the "first quarter" phase, because the Moon is a quarter of the way through its phases.
So, that's why we see the half Moon at a "quarter" phase.
It does cause confusion.
What else can I help you with?

The phase where the moon looks like a semicircle is called the "first quarter" or "last quarter," depending on its position in the lunar cycle.

Both phases showcase the same amount of illumination (50% of the lunar surface), but they are opposite each other in the lunar cycle, with the first quarter appearing in the evening sky and the third quarter in the morning sky.

because only half of the visible moon is lite. we only see half the moon so only a quarter of the moon is lite.===================================Another take:After the New Moon . . .-- The 'first quarter' is the phase that's seen after 1/4 of the timeuntil the next New Moon has passed.-- The 'third quarter' is the phase that's seen after 3/4 of the timeuntil the next New Moon has passed.
