Zoroastrianism - Terminology

Terminology

The Oxford English Dictionary attests use of the term Zoroastrianism in 1874 in Archibald Sayce's Principles of Comparative Philology. The first surviving reference to Zoroaster in Western scholarship is attributed to Thomas Browne (1605–1682), who briefly refers to the prophet in his 1643 Religio Medici. The OED records 1743 (Warburton, Pope's Essay) as the earliest reference to Zoroaster.

The term Mazdaism /ˈmæzdə.ɪzəm/ is a typical 19th century construct, taking Mazda- from the name Ahura Mazda and adding the suffix -ism to suggest a belief system. The March 2001 draft edition of the OED also records an alternate form, Mazdeism, perhaps derived from the French Mazdéisme, which first appeared in 1871. The Zoroastrian name of the religion is Mazdayasna, which combines Mazda- with the Avestan language word yasna, meaning "worship, devotion".

In English, an adherent of the faith commonly refers to himself or herself as a Zoroastrian or as a Zarathustrian. An older, but still widespread expression is Behdin, meaning "follower of Daena", for which "Good Religion" is one translation. In the Zoroastrian liturgy, the term Behdin is also used as a title for an individual who has been formally inducted into the religion in a Navjote ceremony.
