What does emissive mean?

Emissive is used to describe things that emit or involve emission—the discharge or release of things like gas, heat, light, or sound.

Emit means to release or discharge something. Emission can refer to the process of emitting or something that has been emitted, as in carbon emissions.

Emissive is often used to describe things that give off light or heat. The term LED stands for “light-emitting diode,” a semiconductor device that emits light when conducting current and is used in things like TVs and light bulbs.

Example: When it comes to the emission of carbon dioxide, cars and airplanes are much more emissive collectively than volcanoes.

Where does emissive come from?

The first records of the word emissive come from the 1730s. It ultimately derives from the Latin verb ēmittere, from e-, meaning “out of,” and mittere, “to send.”

To emit something is to send it out or give it off, often in a passive way. Emissive is applied to things involving this process. A certain material may be described as more emissive than another in terms of how much heat it emits. In the context of computer graphics, emissive is sometimes used to describe objects that give off light.
