Pronunciation

  • Classical: [foe̯.dɛˈraː.ti.oː][1]
  • Ecclesiastical: [fe.deˈrat.t͡si.o][1]

Forms

foederātiō f (genitive foederātiōnis); third declension[1]

Etymology

It is from Latin foederō (“to make a treaty; to unite”) + -tiō,[1][2][3] and foederō comes from foedus2 (“treaty, league”).[4][5]

Earliest recorded meaning

It is a Late Latin word,[1][6] first found in Jerome, who calls the bond between a mother and her daughter secundaque post deum foederātiō, “the union next after God”.[2][7]

Semantic evolution

Rufinus used it of mystic unions in pagan rites, and the Latin version of Origen's On First Principles of the soul's union with the Word of God;[2][7][8] Cassiodorus speaks of a wonderful union.[2][7][8] Church writers kept the sense of a union or bond.[3][9]

Medieval writers used it for any joining, marriage included, and for a peace treaty: the Frankish royal annals say that in 773 the march against the Saxons was left without any treaty.[10] It also meant an alliance or league.[11][6] It is the source of Italian federazione,[7] and English federation (1721) came from French fédération.[5]
