The study of Persian language, also known as Farsi, is a branch of linguistics that focuses on the structure, grammar, syntax, and semantic of the Persian language. Persian is an Indo-European language spoken primarily in Iran, Afghanistan, Tajikistan, and other parts of Central Asia. It has a rich literary tradition dating back to over a thousand years, with famous poets and writers such as Rumi, Saadi, and Hafez contributing to its cultural significance. Research in Persian language includes topics such as historical development, dialectal variations, language acquisition, and sociolinguistics. Scholars also study Persian literature, poetry, and linguistic relationships with other Indo-European languages.
