| 释义 | light (once / 16 pages) 1nadjv 2adjadv 3vn 4v 5adj It's pitch black in your room so you switch on the lamp, and your room is filled with light. Light is a source of illumination, whether a natural one (like the sun) or an artificial one (like your lamp). Like light itself, the word can take a lot of different forms — it can be a noun, an adjective, or a verb, and it can mean "bright" or "not heavy". No matter how you define it, though, the word comes from the Old English word leoht.
