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”) + -āria (“-ary”). Paralleled in Middle English and Early Modern English by forms from Anglo-Norman justiserie (“judgeship, judiciarship”), from Anglo-Norman and Middle French justicerie (“judgeship; tribunal”), from justice + -ery. As a translation of various Continental European offices, via Middle French justicier, Spanish justiciero, etc.
