  • IPA (Ecclesiastical): [ˈriː.tus][1]

Forms

rītus m (genitive rītūs); fourth declension[1]

Etymology

It is inherited from Proto-Italic *reitu- (“rite”), from the root Proto-Indo-European *h₂rey- (“to count, observe carefully”).[2][1] Cognate with Ancient Greek ἀριθμός (arithmós, “number”) and Old Irish rím (“number”), and perhaps Sanskrit ऋत (ṛtá, “sacred order”).[2][3] The ablative rīte “duly” may point to an older i-stem.[2]

Earliest recorded meaning

De Vaan dates it from Plautus, and Köbler from Lucretius.[2][4] An early inscription orders that the customary rites should not be interrupted.[3] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

It was a religious observance, rite or ceremony, usually in the plural.[3] The ablative with a genitive, rītū, meant “in the manner of, like”, as pecudum rītū “like cattle” in Cicero.[3][5] In a general sense it was a custom or usage, and Festus glosses it as mōs vel cōnsuētūdō.[5][6]

Medieval writers used it of Christian, Jewish and pagan rites, and of a religion as a whole.[7] English rite came from it in the early 14th century and rītuālis gave English ritual in the 1560s.[8] It survives in Italian rito and Spanish rito.[1]
