The word "premise" originates from the Latin praemissa (feminine past participle of praemittere, meaning "to send ahead"). It entered Middle English via Old French premisse, referring to a logical proposition "set before" a conclusion. The spelling evolved to "premise" in Modern English, retaining the core idea of something foundational or prior. The secondary meaning ("building") arose from legal documents listing property boundaries in their opening (premise) clauses.
