A person who has been converted to a religion or belief system; a convert.
Convert + -ite (person belonging to a group, as in Israelite, Levite). A specialized or archaic term for a convert, modeled on historical religious group names.
The suffix -ite originally came from Hebrew and Greek (Israelite, Nazarite) and was borrowed to create status-marking words in English. Calling someone a 'convertite' sounds formal and a bit old-fashioned—modern English just says 'convert.'
