In logic, a relationship between statements where one statement necessarily follows from another; if the first is true, the second must be true. It represents the strongest form of logical connection between propositions.
From Old French entailler, meaning 'to cut into,' originally a legal term for restricting inheritance. The logical usage evolved from the idea that premises 'cut into' or restrict what conclusions can legitimately follow.
Entailment is like a logical leash – once you accept the first statement, you're automatically pulled toward accepting what it entails! There's no escape from the conclusion if you truly accept the premise.
