Forms

disiūnctus (feminine disiūncta, neuter disiūnctum); first/second-declension adjective; comparative disiūnctior, superlative disiūnctissimus[1] It is also spelled diiūnctus and disjūnctus.[1][2] The adverb is disiūnctim.[2]

Etymology

It is the perfect passive participle from Latin disiungō (“to unyoke, separate”), used as an adjective.[1][3][2] disiungō is a compound of dis- and iungō (“to join, yoke”),[4] which de Vaan traces to Proto-Italic *jung-e/o- and Proto-Indo-European *(H)iunégti (“to yoke”).[5] Cognate with Sanskrit युनज्मि (yunájmi, “I yoke”), Ancient Greek ζεύγνυμι (zeúgnumi, “to yoke”) and Lithuanian jùngti (“to tie, join, yoke”).[5]

Earliest recorded meaning

Köbler dates it from Cicero,[4] who speaks of a war waged in two widely separated places, duobus in locis disiunctissimis.[1]

Semantic evolution

It means separated, distant or set apart, and of words or style disconnected.[1] It also means different or distinct: Cicero says that the teachers of living and of speaking were once not different people but the same.[1] Paulus in the Digest uses it of things treated separately, the Rhetorica ad Herennium of clauses distinguished by different synonyms, and Gellius of disjunctive propositions.[1] Wiktionary notes its use as a taxonomic epithet, “separated, distinct”.[2]
