-an
-an or is a Persian suffix of the Middle Persian and New Persian language. It is a suffix for location, plural formation, formation of infinitives, adverb, and personal pronouns. Birgit Anette Olsen points out that "ne of the functions of the Iranian Suffix -an is the derivation of."
In some other Indo-European languages, particularly English, the -an suffix is added to a word denoting an action or an adjective that suggests pertaining to, thereby forming an agent noun. As such, there are many demonyms which end in this suffix. The root of such agent nouns are sometimes derived from the Latin suffix -ia, with the -ia suffix denoting a feminine ending for adjectives.
