Mandaic, or more specifically Classical Mandaic, is the liturgical language of Mandaeism and a South Eastern Aramaic variety in use by the Mandaean community, traditionally based in southern parts of Iraq and southwest Iran, for their religious books. Mandaic, or Classical Mandaic, is still used by Mandaean priests in liturgical rites. The modern descendant of Mandaic or Classical Mandaic, known as Neo-Mandaic or Modern Mandaic, is spoken by a small group of Mandaeans around Ahvaz and Khorramshahr in the southern Iranian Khuzestan province.
Liturgical use of Mandaic or Classical Mandaic is found in Iran (particularly the southern portions of the country), in Baghdad, Iraq and in the diaspora (particularly in the United States, Sweden, Australia and Germany). It is an Eastern Aramaic language notable for its abundant use of vowel letters (mater lectionis with aleph, he only in final position, ‘ayin, waw, yud) in writing, so-called plene spelling (Mandaic alphabet) and the amount of Iranian and Akkadian language influence on its lexicon, especially in the area of religious and mystical terminology. Mandaic is influenced by Jewish Aramaic, Samaritan Aramaic, Hebrew, Greek, Latin, in addition to Akkadian and Parthian.
