Which term is used to describe the omission of a word or phrase that is grammatically necessary but can be inferred from context?

The term that describes the omission of a word or phrase that is grammatically necessary but can be inferred from context is ellipsis. In literature and everyday language, ellipsis allows for the omission of parts of sentences that are understood from the surrounding context, streamlining communication without losing meaning. For instance, in the sentence "I went to the store and she to the park," the verb "went" is omitted in the second clause but can be easily inferred. This device is particularly effective in poetry and conversational speech, where brevity and rhythm are valued.

In contrast, enjambment refers specifically to the continuation of a sentence or clause across a line break in poetry, while clarity involves expressing ideas in a straightforward and unambiguous manner. Reduction generally refers to simplifying complex information but does not specifically pertain to the grammatical omission of words or phrases. Thus, ellipsis is the most precise term for the described concept.
