perjured

The word 'perjured' is built upon the Latin verb perjurare, meaning "to swear falsely," which itself is a compound of the intensive prefix per- ("thoroughly") and jurare ("to swear"). The root jus/jur- carries the fundamental concept of law and oath, tracing back to Proto-Indo-European yewes- meaning "law." The literal sense is thus "to swear thoroughly," but with the negative connotation of swearing a complete falsehood. The addition of the English past participle suffix -ed creates an adjective and verb form that specifically denotes the state or action of having violated a formal oath before a legal authority.

Structure: per (through, thoroughly) + jur (swear, law) + ed (adjective/verb suffix) per: Latin origin, meaning "through, thoroughly". It functions as an intensive prefix. jur: Latin origin, from jus, juris meaning "law, right, oath". It functions as the core root. ed: Old English origin, a suffix used to form the past tense and past participle of verbs, and adjectives from nouns/verbs.
