Pronunciation

  • Classical: [kɔm.paˈkiːs.kɔr][1]
  • Ecclesiastical: [kom.paˈt͡ʃis.kor][1]

Forms

compacīscor (present infinitive compacīscī, perfect active compactus sum); third conjugation, deponent[1] Plautus and the dictionaries also have ⟨compecīscor⟩, with the perfect compectus sum.[2][3][4] According to Georges, the grammarian Charisius says the present tense was not in use.[3]

Etymology

It is from Latin com- + pacīscor (“to make an agreement”).[5][6][1] De Vaan lists it among the derivatives of pāx (“peace”), which goes back to Proto-Italic *pāk- (“agreement, peace”) and Proto-Indo-European *peh₂ḱ- (“agreement”).[7]

Earliest recorded meaning

Plautus has it in the perfect: sī sumu' compectī seu cōnsilium umquam iniimus, “if we have made a compact or ever formed a plan”.[5][2][7][8] A fragment of his Cistellaria has mēcum mātrimōniō compecta sit, of a woman pledged in marriage.[2][3]

Semantic evolution

In Classical Latin it is rare and found only in the perfect tenses and the participle.[2] The neuter participle became the noun compectum, “agreement”, used chiefly in the phrase dē compectō or the ablative compectō, “by previous arrangement”.[5][2]

The verb came back in medieval charters: a Hungarian document of 1230/1231 says that certain servants had come to an agreement with a count,[9] and Polish documents use the participle in a passive sense, “agreed upon”.[10] In the Czech lands it was used of choosing an arbitrator by agreement and of being joined by treaty.[11]

Timeline

  • c. 250–184 BC – Plautus uses the perfect compectī sumus.[5][7][8]
  • 1230/1231 – A Hungarian charter uses it of an agreement with a count.[9]
