Vocabulary, phrases, and sometimes entire languages that are considered sacred or significant within a particular faith. This encompasses not only the spoken and written aspects but also the scriptural and liturgical languages that are used in religious texts, prayers, and rituals. For instance, Sanskrit is revered in Hinduism, Pali in Theravada Buddhism, Hebrew in Judaism, Arabic in Islam, and Old Church Slavonic in Eastern Orthodox Christianity. These languages carry with them a sense of the sacred, and their use often reinforces religious identity and continuity with the past. They can be a key part of the religious experience, providing a direct link to the foundational texts and concepts of the faith.
