justiciary

Etymology

From Late Latin justitiaria, justiciaria ("judgeship, judiciarship; court sessions"), justitiarius, and justiciarius ("justiciar, judge, justice [of the peace]; judiciary, related to justice"), all from Latin iūstitia ("justice") plus -āria ("-ary"). This runs alongside forms in Middle English and Early Modern English drawn from Anglo-Norman justiserie ("judgeship, judiciarship"), from Anglo-Norman and Middle French justicerie ("judgeship; tribunal"), from justice plus -ery. As a rendering of various Continental European offices, it came via Middle French justicier, Spanish justiciero, and so on.
