Facts about Farsi.
The official language of Iran, Afghanistan, and Tajikistan, Persian (also called Farsi) is part of the Indo-Iranian branch of the Indo-European language family.

About the Persian language.
With over 110 million speakers worldwide, Persian (Farsi) is primarily spoken in Iran and neighboring regions, with large pockets of speakers peppered around the world, including in the United States. Its script is based on the Arabic alphabet with the addition of four letters: پ [p], چ[t͡ʃ], ژ [ʒ], and گ [g]. The addition of lines, dots, and other shapes help to create the non-Arabic sounds of Persian.
Persian culture and literature.
The Persian language has a rich literary tradition, with its poetry perhaps the most renowned form of literature. Omar Khayyám (1048–1131) was an astronomer, mathematician, and poet—well known internationally because of his mesmerizing quatrains, translated by English writer Edward FitzGerald and published in The Rubáiyát of Omar Khayyám (1859).
