sunlight

What windows admit

Sunlight is the light that comes from the sun.

It illuminates the earth during daytime hours and provides the energy plants need for photosynthesis.

Direct sunlight streams unobstructed from the sun: The room gets good sunlight in the morning.

Figuratively, sunlight suggests openness and transparency: Sunlight is the best disinfectant.
