unanimus

Unanimus is a Latin adjective meaning one mind, in agreement, or of united opinion. In English, the related noun forms unanimity and the adjective unanimous derive from this root, and the word is sometimes used in scholarly or juridical writing to evoke its Latin origin.

Etymology and form: Unanimus comes from the combination of uni- meaning one and animus meaning mind or spirit. The English words unanimous and unanimity entered through Latin and French and have since become standard terms to describe complete agreement within a group.

Usage and meaning: In contemporary English, unanimous is the usual adjective describing a decision or sentiment with total or complete agreement among all participants. Unanimity is the corresponding noun referring to the state or condition of such agreement. In legal and formal contexts, a unanimous verdict or vote denotes that every member approved the outcome, with no dissenting votes.

Contexts and distinctions: Unanimity is often contrasted with broader forms of consensus. While unanimity requires full agreement, consensus can be reached even if some individuals assent without complete endorsement. The term emphasizes unanimity of mind rather than merely broad support.

Related terms and concepts: Related concepts include consensus, accord, and consent. In political science and philosophy, discussions of unanimity relate to how groups make decisions and the conditions under which unanimous outcomes are achievable or stable. In social choice theory, unanimity plays a role in certain decision rules and normative criteria.

Overview: Unanimus functions mainly as a historical linguistic source for the modern terms unanimous and unanimity. Today, the word is chiefly encountered in precise or formal discussions of agreement, particularly in legal, political, or theoretical contexts.
