A‐merce″ment (�), n. [OF. amerciment.] The infliction of a penalty at the discretion of the court; also, a mulct or penalty thus imposed. It differs from a fine,in that the latter is, or was originally, a fixed and certain sum prescribed by statute for an offense; but an amercement is arbitrary. Hence, the act or practice of affeering. [See Affeer.] Blackstone.
☞ This word, in old books, is written amerciament.
Amercement royal, a penalty imposed on an officer for a misdemeanor in his office. Jacobs.
