Pronunciation

  • Ecclesiastical: [ek.skom.mu.niˈkat.t͡si.o][1]

Forms

excommūnicātiō f (genitive excommūnicātiōnis); third declension[1]

Etymology

It is formed from Latin excommūnicō + -tiō.[2][3] The verb is formed from ex- and commūnicō (“to share, have communion”).[1] De Vaan puts commūnis (“common”) with mūnus (“duty, gift”), from Proto-Italic *moini-, perhaps from Proto-Indo-European *h₂moi-ni- (“exchange”).[4]

Earliest recorded meaning

It is a Christian word,[2] found first in Jerome, who uses it in his translation of Origen's homilies on Jeremiah and in his books against Rufinus, for exclusion from the communion of the Church.[2][5]

Semantic evolution

The TLL defines it as exclusion from the communion of the Church, above all from the sacrament of the altar, and finds it used beside anathema.[2] Augustine uses it several times.[6][7][2]

In Medieval Latin it remained the term of canon law for the ban of the Church,[8][9] distinguished by degree,[10] and was also used more generally for exclusion.[9] The Codes of Canon Law keep it as a censure that excludes a Catholic from communion with the faithful.[11] English borrowed it in the mid-15th century as excommunication.[12]

Timeline

  • c. 383–419/420 AD – Jerome uses it for exclusion from the Church.[2][13]
