Entailment

As explained in LLMs in Production

Entailment is information or an implication supported by context beyond the literal text that is explicitly stated.

A sentence can suggest more than it explicitly says. In conversation, shared knowledge lets people take shortcuts: listeners use context and lived experience to fill in unstated details. This is part of pragmatics. The resulting implications may feel obvious, but they are not necessarily guaranteed by the words alone. section 2.1.1

What an ICU headline suggests

“A popular celebrity was just taken into the ICU” may suggest a serious injury and hospital treatment. Those details depend on knowing what an ICU and a hospital are, not just reading the sentence. A reference to unfamiliar Slovak Easter traditions shows the limit: without the relevant cultural knowledge, much of the intended meaning remains unclear. section 2.1.1
