moonlight

Moonlight is the soft natural light seen at night when the moon lights the earth. In everyday use, it usually refers to the pale glow that covers fields, streets, water, or a room by the window. That is why the word often appears in romantic, calm, or slightly mysterious scenes. If someone says a beach or a forest was shining in moonlight, they mean it was gently lit by the moon.

The word can also be used as a verb. When someone moonlights, they work at a second job besides their regular one. A teacher might moonlight as a tutor in the evening, or an office worker might moonlight as a driver on weekends. This meaning is common in informal and general English and usually suggests extra work done for more income.

So the word has two main uses: the pale light of the moon, and the act of doing extra paid work outside your main job. The first use is common in stories, descriptions of nature, and emotional scenes. The second use is common when talking about work and money. Both meanings are standard, and the intended sense is usually clear from the context.
