Emitted vs. Omitted: What's the Difference?

Edited by Harlon Moss || By Janet White || Updated on October 5, 2023
Emitted refers to releasing or giving off, like light or sound, while omitted means left out or not included.

Key Differences

Emitted and omitted are English terms with distinct meanings and usages. Emitted primarily refers to the release or discharge of something such as light, sound, or a substance. It conveys an action where something is sent forth or expressed by a source, often involving the expulsion of energy or matter. The term can relate to various contexts, including scientific, environmental, and general, where something is propelled or emanated from a particular origin or source.
On the other hand, omitted pertains to neglecting to include, mention, or perform something. It implies an absence or exclusion, intentional or unintentional, of an element, detail, or action. It is often used when something is skipped, disregarded, or overlooked in a discussion, document, or process. Omitted reflects a lack or deficiency, representing the non-inclusion or non-performance of something that could have been or should have been considered or executed.
While emitted implies an action of release or expression, radiating or expelling from a source, omitted symbolizes the act of leaving out, an absence, or non-inclusion. Emitted encompasses the projection or expression of substances, energies, or entities from a particular point or object, reflecting an outward movement or manifestation. In contrast, omitted involves the absence or neglect of an element or detail, indicating a lack or deficiency due to non-inclusion or non-mention.
The concept of emitted involves the propagation or discharge of various forms of matter or energy, underlining an active process where something is sent forth or expressed by a source. It is synonymous with release, expel, and radiate, describing the action of giving off or projecting. In contrast, omitted is synonymous with excluded, left out, and skipped, reflecting the inaction or neglect that leads to the absence or non-mention of a specific element or detail.
To summarize, emitted represents a proactive release or discharge from a source, emphasizing the outward flow or expression of matter or energy. In contrast, omitted signifies an absence or exclusion, highlighting the non-inclusion or non-performance of a particular element, action, or detail.
