obsequium

Obsequium is a Latin noun meaning dutiful compliance, obedience, homage, or deference toward a person in authority. In classical and medieval usage, obsequium described the obligations and acts by which a subject or vassal acknowledged the status, authority, or protection of a lord or sovereign, typically including formal homage, service, and loyal behavior. The term could denote both neutral, proper submission and, when used critically, excessive or servile deference.

Etymology: The word originates in Latin. It is closely related to obsequious in English, with both conveying the idea of dutiful submission toward a superior.

Modern usage: In scholarly writing, obsequium is encountered in discussions of feudal relationships, ceremonial culture, and the rhetoric of power. In contemporary English, it is relatively rare outside historical or linguistic contexts; obsequiousness is the more common term when describing behavior that is overly eager to please.
