What is the term for the omission of a word or phrase which is necessary but can be deduced from the context?

The term that describes the omission of a word or phrase that is necessary but can be logically inferred from the surrounding context is ellipsis. This concept is frequently encountered in various forms of writing, where the omitted part is understood by the reader without needing to be explicitly stated.

For example, in the sentence "I went to the store, and she to the park," the phrase "went" is omitted after "she," yet the meaning remains clear due to the previous context. The use of ellipsis can enhance the flow of writing and create a more streamlined expression.

The other terms mentioned do not accurately reflect this specific concept. Conciseness refers to the quality of being brief and to the point, which does not inherently involve omission based on context. Abbreviation refers to shortening words or phrases, while abridge means to shorten a text without losing its essential meaning, but neither captures the nuanced nature of contextually deduced omissions like ellipsis does.
