Emission and omission are two words that are very close in pronunciation and spelling, but have very different meanings. They are often confused. We will examine the definitions of the words emission and omission, where they came from and some examples of their use in sentences.

An emission is a discharge of something. Often, an emission is a release of gas or radiation into the atmosphere, or a discharge of bodily fluid. The word emission is derived from the Latin word emissionem, meaning releasing or sending out. Emission is related to the verb, emit. The plural form of emission is emissions.

An omission is something that has been excluded, something left out either by mistake or by design. An omission may be a simple mistake that is easily rectified or a failure to realize a legal or moral obligation, resulting in dire consequences. The word omission, related to the verb omit, is derived from the Latin word omissionem, meaning leaving something out. The plural form of omission is omissions.
