Ultimate origin
Proto-Indo-European (*tlokʷ-)

Pronunciation

  • Classical: [kɔlˈlɔ.kʷi.ũː][1]
  • Ecclesiastical: [kolˈlɔː.kʷi.um][1]

Forms

colloquium n (genitive colloquiī or colloquī); second declension[1] It is also spelled conloquium.[2][3]

Etymology

It is formed from colloquor (“to talk with”) with the suffix -ium.[2][1][3] The verb is com- (“together”) and loquor (“to speak”), which de Vaan traces to Proto-Italic *tlokʷe/o- and Proto-Indo-European *tlokʷ- (“to talk”).[4] Cognate with Old Irish ad·tluchedar (“gives thanks”) and Russian толк (tolk, “meaning”).[4]

Earliest recorded meaning

The TLL and the OLD find it first in the comic poet Turpilius, of private talk: cessō mē in colloquium cōnferre?, “why don't I join their conversation?”.[3][2][5]

Semantic evolution

It is talk between persons, entering into talk with someone (Sallust), company and conversation as a sign of social life (Cicero misses everyone's colloquium in his solitude), and talk by letter.[2] It is also a conference or discussion, an interview one asks for (Nepos), and in war a parley with the enemy.[2][6]

In medieval Latin it named an audience with a ruler, a general assembly of the king's men, a session of the royal court or of a law court, a church synod, a town assembly and the general chapter of the Premonstratensians.[7] English took it over as colloquium around 1600, at first for a conversation, and earlier as colloquy in the mid-15th century.[8]

Timeline

  • 2nd century BC – Turpilius of a private conversation.[2][3][5]

  • mid-15th century – English colloquy.[8]
  • c. 1600 – English colloquium, “conversation”.[8]
