Here's a breakdown:
* The Moon doesn't produce its own light. It's a large, rocky body in space that doesn't have an internal source of light like a star.
* Sunlight hits the Moon's surface. The Sun's light travels through space and reaches the Moon.
* The Moon's surface reflects the sunlight. Different parts of the Moon's surface reflect light differently, depending on the composition and texture of the material. Some areas are darker and reflect less light (like the lunar maria, which are ancient volcanic plains), while others are brighter and reflect more light (like the lunar highlands).
* We see the reflected sunlight as moonlight. The reflected sunlight from the Moon reaches our eyes, and we perceive it as the Moon's light.
Therefore, the meaning of the light reflected from the Moon's surface is simply that it's sunlight that has been reflected off the lunar surface.
