seneschal
Seneschal (noun) means a steward, especially, in the past, one who ran a medieval lord's household.
Etymology
Came into English as Middle English seneschal (first recorded in 1393), from Old French seneschal, which traces to Medieval Latin siniscalcus, from Frankish *siniskalk, from Proto-Germanic *siniskalkaz, built from Proto-Germanic *siniz (“senior”) and *skalkaz (“servant”) — the second element also found in marshal. As a title for an officer of the French crown, it came via French sénéchal.
