The antonym for the word "more moonlit" would be "less moonlit." It means the darkness prevails over moonlight. Sometimes, the environment requires dim lighting, and in such cases, the moon doesn't provide enough light. The opposite of a more moonlit sky is a faintly lit or totally dark sky. It happens during a new moon, an eclipse, or cloudy evenings. The absence of the moon's glow brings out the stars' beauty and makes them brighter. During a less moonlit night, the light sources on the ground become more noticeable, and things like street lights, car lights, and house lights become more visible.
