late 14c., in logic, "a previous proposition from which another follows," from O.Fr. premisse
, from M.L. premissa (propositio)
"(the proposition) set before," fem. pp. of L. praemittere
"send or put before," from prae-
"before" + mittere
"to send" (see mission
). In legal documents it meant "matter previously stated" (early 15c.), which in deeds or wills often was a house or building, hence extended meaning of "house or building, with grounds" (1730). The verb meaning "to state before something else" is from 1520s.
