There is no big difference between light and lite. Both words are used to describe materials that are not too heavy in terms of their composition. Light comes from the Greek word 'leukos' and in Latin, it is called 'lux'. Light simply means the illumination that an object produced. Light can be used as a noun; it can be used as a verb and also as an adjective. As a noun, it refers to the illumination that comes from an object. For example: Can you see the brightness of the light coming from the sun?
As a verb, it means to set fire to something, for example: can you tell the boy to light the candles? As an adjective, you can simply say, the table is very light, which means the table has little weight. Lite, on the other hand, is from the French word 'lite,' which describes an object that is light in composition, or products with fewer calories and fat
