A place for the confinement of persons in lawful detention: jail, brig, prison, slammer.
First used in English in 1908. From Spanish juzgado (court), past participle of juzgar (to judge), from Latin judicare (to judge). Ultimately from Indo-European root deik- (to show or to pronounce solemnly) that is also the source of other words such as judge, verdict, vendetta, revenge, indicate, dictate, and paradigm.
