emisio

Emisio is a term that appears in various linguistic and technical contexts, though it is not a standard English word. In many languages the noun for the act of sending forth or releasing something is related to the Latin emissio, from which English derives the word emission. The form "emisio" can be encountered as a transliteration, historical spelling, or in languages that preserve older Latin spellings. In practice, the concept behind emisio is the act of sending out energy, matter, or signals.

In scientific usage, the related idea is commonly expressed as emission. Emission covers phenomena such as thermal emission, electromagnetic emission, and chemical or gas emission. In physics, astronomy, and chemistry, emissions are characterized by their spectrum, intensity, and origin. In environmental policy and industry, the focus is on emissions of pollutants or greenhouse gases and the regulatory measures intended to limit them. Although "emisio" may appear in some language texts as a variant or root form, the term most widely used in English is emission, with specific descriptors like emitter, emissivity, or emissive related terms used to describe sources and properties of emitted energy or particles.

As a proper noun, Emisio or similarly spelled names may occur as place names or surnames in certain regions, but such uses are rare and not widely documented in English-language reference works. For most readers seeking information on the concept, the related English term emission provides the standard reference point. See also: emission, emitter, emissivity.
