What term refers to something that has been left out or excluded?

The term "omitted" specifically refers to something that has been left out or excluded from a particular context. In various scenarios, whether in writing, speech, or any form of communication, information that is omitted is intentionally or unintentionally not included, which can be significant because it may lead to misunderstandings or gaps in information.

For instance, in a text or a discussion, if crucial details are omitted, it can alter the meaning or the effectiveness of the communication. The notion of omission carries implications about the importance of transparency and completeness, making it a vital concept in both literacy and critical thinking.

The other terms do not convey the same meaning: "included" signifies something that has been added rather than left out, "ignored" implies a disregard for something, and "presented" means something that has been brought forth or introduced. Thus, "omitted" is the only term that directly addresses the idea of exclusion.
