premise: [14] Premise comes via Old French premisse from medieval Latin praemissa, a noun use of the past participle of Latin praemittere ‘send ahead’. This was a compound verb formed from the prefix prae- ‘before’ and mittere ‘send’ (source of English admit, commit, mission, transmit, etc). It first entered English as a technical term in logic, in which its underlying meaning is of a proposition ‘set before’ someone.

But it was also used in the plural as a legal term, meaning ‘matters stated previously’. In a conveyance or will, such ‘matters’ were often houses or other buildings referred to specifically at the beginning of the document, and so the term premises came to denote such buildings.
