New Persian

New Persian texts written in the Arabic script first appear in the 9th-century.[18] The language is a direct descendant of Middle Persian, the official, religious and literary language of the Sasanian Empire (224–651).[19] However, it is not descended from the literary form of Middle Persian (known as pārsīk, commonly called Pahlavi), which was spoken by the people of Fars and used in Zoroastrian religious writings. Instead, it is descended from the dialect spoken by the court of the Sasanian capital Ctesiphon and the northeastern Iranian region of Khorasan, known as Dari.[18][20] Khorasan, which was the homeland of the Parthians, was Persianized under the Sasanians. Dari Persian thus supplanted Parthian language, which by the end of the Sasanian era had fallen out of use.[18] New Persian has incorporated many foreign words, including from eastern northern and northern Iranian languages such as Sogdian and especially Parthian.[21]

The mastery of the newer speech having now been transformed from Middle into New Persian was already complete by the era of the three princely dynasties of Iranian origin, the Tahirid dynasty (820–872), Saffarid dynasty (860–903) and Samanid Empire (874–999), and could develop only in range and power of expression.[22] Abbas of Merv is mentioned as being the earliest minstrel to chant verse in the newer Persian tongue and after him the poems of Hanzala Badghisi were among the most famous between the Persian-speakers of the time.[23]

The first poems of the Persian language, a language historically called Dari, emerged in Afghanistan.[24] The first significant Persian poet was Rudaki. He flourished in the 10th century, when the Samanids were at the height of their power. His reputation as a court poet and as an accomplished musician and singer has survived, although little of his poetry has been preserved. Among his lost works are versified fables collected in the Kalila wa Dimna.[25]

The language spread geographically from the 11th century on and was the medium through which among others, Central Asian Turks became familiar with Islam and urban culture. New Persian was widely used as a trans-regional lingua franca, a task for which it was particularly suitable due to its relatively simple morphological structure and this situation persisted until at least the 19th century.[26] In the late Middle Ages, new Islamic literary languages were created on the Persian model: Ottoman Turkish, Chagatai, Dobhashi and Urdu, which are regarded as "structural daughter languages" of Persian.[26]

"Classical Persian" loosely refers to the standardized language of medieval Persia used in literature and poetry. This is the language of the 10th to 12th centuries, which continued to be used as literary language and lingua franca under the "Persianized" Turko-Mongol dynasties during the 12th to 15th centuries, and under restored Persian rule during the 16th to 19th centuries.[27]

Persian during this time served as lingua franca of Greater Persia and of much of the Indian subcontinent. It was also the official and cultural language of many Islamic dynasties, including the Samanids, Buyids, Tahirids, Ziyarids, the Mughal Empire, Timurids, Ghaznavids, Karakhanids, Seljuqs, Khwarazmians, the Sultanate of Rum, Delhi Sultanate, the Shirvanshahs, Safavids, Afsharids, Zands, Qajars, Khanate of Bukhara, Khanate of Kokand, Emirate of Bukhara, Khanate of Khiva, Ottomans and also many Mughal successors such as the Nizam of Hyderabad. Persian was the only non-European language known and used by Marco Polo at the Court of Kublai Khan and in his journeys through China.[28]

Qajar dynasty

In the 19th century, under the Qajar dynasty, the dialect that is spoken in Tehran rose to prominence. There was still substantial Arabic vocabulary, but many of these words have been integrated into Persian phonology and grammar. In addition, under the Qajar rule numerous Russian, French, and English terms entered the Persian language, especially vocabulary related to technology.

The first official attentions to the necessity of protecting the Persian language against foreign words, and to the standardization of Persian orthography, were under the reign of Naser ed Din Shah of the Qajar dynasty in 1871. After Naser ed Din Shah, Mozaffar ed Din Shah ordered the establishment of the first Persian association in 1903.[29] This association officially declared that it used Persian and Arabic as acceptable sources for coining words. The ultimate goal was to prevent books from being printed with wrong use of words. According to the executive guarantee of this association, the government was responsible for wrongfully printed books. Words coined by this association, such as rāh-āhan (راه‌آهن) for "railway", were printed in Soltani Newspaper; but the association was eventually closed due to inattention.

A scientific association was founded in 1911, resulting in a dictionary called Words of Scientific Association (لغت انجمن علمی), which was completed in the future and renamed Katouzian Dictionary (فرهنگ کاتوزیان).[30]

Pahlavi dynasty

The first academy for the Persian language was founded on 20 May 1935, under the name Academy of Iran. It was established by the initiative of Reza Shah Pahlavi, and mainly by Hekmat e Shirazi and Mohammad Ali Foroughi, all prominent names in the nationalist movement of the time. The academy was a key institution in the struggle to re-build Iran as a nation-state after the collapse of the Qajar dynasty. During the 1930s and 1940s, the academy led massive campaigns to replace the many Arabic, Russian, French, and Greek loanwords whose widespread use in Persian during the centuries preceding the foundation of the Pahlavi dynasty had created a literary language considerably different from the spoken Persian of the time. This became the basis of what is now known as "Contemporary Standard Persian".

Standard Persian is the standard variety of Persian that is the official language of the Iran[8] and Tajikistan[38] and one of the two official languages of Afghanistan.[39] It is a set of spoken and written formal varieties used by the educated persophones of several nations around the world.[40]

As Persian is a pluricentric language, Standard Persian encompasses various linguistic norms (consisting of prescribed usage). Standard Persian practically has three standard varieties with official status in Iran, Afghanistan, and Tajikistan. The standard forms of the three are based on the Tehrani, Kabuli, and Bukharan varieties, respectively.[41][42]
