7. Etymology: "to manage as a steward" from Old French aministrer, from Latin administrare, "to serve, to carry out, to manage"; from ad-, "to" + ministrare, "to serve".
The minister part of administer came from about 1300 meaning, "someone who acts by the authority of another person" from Old French ministre "servant" which came from Latin minister, ministri, "servant, priest's assistant" (in Middle Latin, "priest"), from minus, minor, "less".
The meaning of "priest" was established in English from the early 14th century. The political sense of "a high officer of the state" is determined from the 1620s from the concept of "service to the crown". The verb is from about 1300, originally meaning "to serve (food or drinks)".
