What does sunlight mean?
Sunlight is the light produced by the sun and falling on the earth. The word is used when discussing illumination, weather, photography, architecture, agriculture, or the effects of exposure to the sun. As a mass noun, sunlight is normally uncountable and does not take a regular plural. It can be modified by terms such as direct, indirect, bright, or morning, and is frequently paired with phrases such as “in the sunlight” and “a ray of sunlight.” Unlike sunshine, which often evokes pleasant, warm weather, sunlight is more literal and can refer neutrally to the physical light. In figurative contexts, it may evoke visibility, optimism, or the exposure of something previously hidden, although these associations are secondary to its everyday meaning.
nounThe light that comes from the sun. It can refer to sunlight in general or to direct light falling on a particular place or object.
- The natural light emitted by the sun, especially as it falls on a place or object.
"Morning sunlight streamed through the open window."
"Plants grow best when they receive several hours of sunlight each day."
"The old photograph had faded badly after years of exposure to sunlight."
Sunlight takes about eight minutes and twenty seconds to reach Earth, so every sunny moment is literally a glimpse of the past.
