According to the whole

Glossary

The vocabulary of the Orthodox Church: the services and their books, the vessels and vestments, the orders of clergy and monastics, the calendar and the fast, and the terms of the ascetic and theological tradition. Each word is given in its source language where one exists.

The Greek, Church Slavonic and other forms beside each term are the word in its own tongue, and belong to the entry itself rather than being a rendering of the definition into that language.
