Persian

Persian is an Iranian language within the Indo-Iranian branch of the Indo-European languages. It is primarily spoken in Iran, Afghanistan, Tajikistan, and other countries which historically came under Persian influence. The Persian language is classified as a continuation of Middle Persian, the official religious and literary language of Sassanid Iran, itself a continuation of Old Persian, the language of the Persian Empire in the Achaemenid era. Persian is a pluricentric language and its grammar is similar to that of many contemporary European languages. Wikipedia
