foederō (present infinitive foederāre, perfect active foederāvī, supine foederātum); first conjugation[1]
Etymology
It is a back-formation from foederātus “allied by treaty”, from foedus, ⟨foederis⟩ “treaty”.[2][3][1]
Earliest recorded meaning
Lewis and Short say the finite verb is late Latin, and cite Ammianus' cum foederārētur concordia “when concord was sealed by treaty”.[4][5] Köbler dates Ammianus c. 390 AD.[6]
Semantic evolution
It meant to seal, ratify an agreement, to establish by treaty, and the glosses render it to join, unite, associate.[2][4][3]
In Ecclesiastical Latin it meant to establish by agreement, make a treaty.[7] Its Late Latin noun foederātiō gave English federation in 1721 through French.[8]
Timeline
