Pronunciation

  • Classical: [kɔl.laˈboː.roː][1]
  • Ecclesiastical: [kol.laˈbɔː.ro][1]

Forms

collabōrō (present infinitive collabōrāre, perfect active collabōrāvī, supine collabōrātum); first conjugation[1]

Etymology

It is from Latin con- + labōrō (“to work, toil”).[2][3][4][1]

Earliest recorded meaning

The TLL finds it from the Itala and Tertullian on.[2] Tertullian, writing on repentance, says that when one member suffers the whole body must grieve with it and work together for the remedy (condoleat ūniversum et ad remedium conlabōret necesse est).[2][5][6]

Semantic evolution

It is a Christian word.[2][3] It meant first to share labours and sufferings: the Passion of Perpetua has hīc sum tēcum et conlabōrō tēcum “I am here with you and I labour with you”, and Augustine writes of fellow bishops in Numidia who labour and face danger together.[2] More generally it meant to work together or cooperate, with ad, in, cum or the dative:[2] the Vulgate has collabōrantēs fideī ēvangeliī “striving together for the faith of the gospel”,[2] and Gregory the Great observes that the sight of a fellow worker lightens labour.[2] One late writer uses it for striving hard.[2]

Medieval Latin kept the sense of working together,[7][8][9] and in law codes and charters, with the force of the prefix weakened, it came to mean to acquire by labour and to cultivate land; the participle collabōrātum became a noun for what had been earned or acquired.[7] In Polish records it means to finish field work and bring in the harvest.[10] English collaborate, recorded from 1845, may come from its past participle or from French.[11]

Usage notes

It is often spelled conlabōrō.[2][7] A late grammatical treatise quoted by the TLL explains the unassimilated prefix by the meaning: ⟨con-⟩ stays whole before ⟨l⟩ when the verb always involves more than one person, as in conlabōrō and conlaudō, but becomes ⟨col-⟩ in verbs such as collocō and colligō.[2]
