From Latin 'injungere' (to yoke upon) — a court order literally 'yoked upon' someone by authority.
An authoritative warning or order; (law) a judicial order requiring a person to do or refrain from doing a particular act.
From Late Latin injūnctiōnem (accusative of injūnctiō, an enjoining, an imposition of obligation), from the past participle of Latin injungere (to join upon, to impose, to lay upon, to enjoin), composed of in- (upon, against, into) and jungere (to join, to yoke, to bind together), from PIE *yewg- (to join, to yoke). PIE *yewg- is one of the foundational roots of social and physical connection in Indo-European, producing Latin jungere and its derivatives jugum (yoke), conjugal (yoked together), junction, conjunction, disjunction, subjugate (to bring under the yoke), yoga (from Sanskrit yuj, to yoke — the same PIE root in its Sanskrit branch), and yoke itself in English (from Old English geoc, from Proto-Germanic *jukan).
