Forms

iūnctus (feminine iūncta, neuter iūnctum, comparative iūnctior, superlative iūnctissimus); first/second-declension adjective[1]

Etymology

The adjective is from Latin iungō (“to join, yoke”), its perfect passive participle.[1][2] De Vaan traces iungō to Proto-Italic *jung-e/o- and a nasal present Proto-Indo-European *(H)iunégti (“to yoke”).[3]

Earliest recorded meaning

Cicero has it first as an adjective, in the De inventione, of a case in law that is compound rather than simple.[1][4]

Semantic evolution

Cicero also uses it of a cause closely linked with its effect and of combined ends.[1][2] Livy and Ovid use it of places next to each other;[1][4] Ovid and later writers also use it of people closely connected by friendship or kinship, often in the superlative.[1][4] Pliny the Younger uses it of horses driven as a pair.[1][4] Gellius reports Nigidius calling avārus not a simple but a compound word.[1]

Timeline

  • 81–43 BC – Cicero uses it of a compound case and of closely linked things.[1][5]
  • 59 BC–17 AD – Livy uses it of mountains touching the sky.[1][5]
