Pronunciation

  • Classical: [kõːˈfoe̯.dɛ.roː][1]
  • Ecclesiastical: [koɱˈfɛː.de.ro][1]

Forms

cōnfoederō (present infinitive cōnfoederāre, perfect active cōnfoederāvī, supine cōnfoederātum); first conjugation[1]

Etymology

It is formed from Latin con- + foedus2 (“treaty, league”),[2][1] though the TLL also allows the verb foederō (“to make a treaty”) as its base.[2] The noun goes back to Proto-Italic *feiþ-os- (“trust”) and Proto-Indo-European *bheidh-e/o- (“to trust”).[3]

Earliest recorded meaning

Tertullian is the first to use it, of all the churches joined to the apostolic ones by their fellowship in the sacrament.[2][4]

Semantic evolution

It belongs to Late Latin, mostly to Christian writers.[5][1] Besides its literal sense of joining by a league or alliance, as when Orosius speaks of the Sabine women united by impious marriages,[5] it was used figuratively for joining things closely together: Novatian says that man and the divine are united in Christ,[2] Prudentius uses it of limbs, and Jerome of a friendship just beginning.[5] Ecclesiastical Latin also gave it the sense “to conform”.[6]

Its past participle cōnfoederātus is the source of English confederate (1530s).[7]
