Persian
Persian (local names: فارسی, Farsi IPA: [fɒːɾˈsi]; or پارسی, Parsi IPA: [pɒːɾˈsi], see Nomenclature) is an Iranian language within the Indo-Iranian branch of the Indo-European languages. It is widely spoken in Iran, Afghanistan, Tajikistan, Uzbekistan and Bahrain and has a status of official language in the first three countries under different names. New Persian, which usually is called also by the names of Dari, Farsi, Parsi or Parsi-Dari, can be classified linguistically as a continuation of Middle Persian, the official religious and literary language of Sassanian Iran, itself a continuation of Old Persian, the language of the Achaemenids. Persian is a pluricentric language and its grammar is similar to that of many contemporary European languages. The Persian language has been a medium for literary and scientific contributions to the eastern half of the Islamic world.
Persian has had a considerable influence on neighboring languages, particularly the Turkic languages in Central Asia, Caucasus, and Anatolia, neighboring Iranian languages, as well as Urdu. It has also exerted a smaller influence on Hindi, Punjabi, Sindhi, Saraiki and other South Asian languages, as well as Serbian and other Balkan languages (via Turkish).
Persian belongs to the Western group of the Iranian branch of the Indo-European language family, and is of the subject object verb type. The Western Iranian group contains other related languages such as Kurdish, Mazandarani, Gilaki, Talyshi and Baluchi. The language is in the Southwestern Iranian group, along with and very similar to the Tat language of Caucasus Larestani and Luri languages.
Persian is an Iranian tongue belonging to the Indo-Iranian branch of the Indo-European family of languages. In general, Iranian languages are known from three periods, usually referred to as Old, Middle, and New (Modern) periods. These correspond to three eras in Iranian history; Old era being the period from sometime before Achaemenids, the Achaemenid era and sometime after Achaemenids (that is to 400-300 BC), Middle era being the next period most officially Sassanid era and sometime in post-Sassanid era, and the New era being the period afterwards down to present day.
According to available documents, Persian language is the only Iranian language all whose three Old, Middle, and New stages are known to represent one and the same language; i.e. New Persian is a direct descendent of Middle and Old Persian.
The oldest records in Old Persian date back to the Persian Empire of the 6th century BC.
The known history of the Persian language can be divided into the following three distinct periods:
Old Persian
Old Persian evolved from Proto-Iranian as it evolved in the Iranian plateau's southwest. The earliest dateable example of the language is the Behistun Inscription of the Achaemenid Darius I (r. 522 BC – ca. 486 BC). Although purportedly older texts also exist (such as the inscription on the tomb of Cyrus II at Pasargadae), these are actually younger examples of the language. Old Persian was written in Old Persian cuneiform, a script unique to that language and is generally assumed to be an invention of Darius I's reign.
After Aramaic, or rather the Achaemenid form of it known as Imperial Aramaic, Old Persian is the most commonly attested language of the Achaemenid age. While examples of Old Persian have been found wherever the Achaemenids held territories, the language is attested primarily in the inscriptions of Western Iran, in particular in Parsa "Persia" in the southwest, the homeland of the tribes that the Achaemenids (and later the Sassanids) came from.
In contrast to later Persian, written Old Persian had an extensively inflected grammar, with eight cases, each declension subject to both gender (masculine, feminine, neuter) and number (singular, dual, plural).
Middle Persian
In contrast to Old Persian, whose spoken and written forms must have been dramatically different from one another, written Middle Persian reflected oral use. The complex conjugation and declension of Old Persian yielded to the structure of Middle Persian in which the dual number disappeared, leaving only singular and plural, as did gender. Middle Persian used prepositions to indicate the different roles of words, for example an -i suffix to denote a possessive "from/of" rather than the multiple (subject to gender and number) genitive caseforms of a word.
Although the "middle period" of Iranian languages formally begins with the fall of the Achaemenid Empire, the transition from Old- to Middle Persian had probably already begun before the 4th century. However, Middle Persian is not actually attested until 600 years later when it appears in Sassanid era (224–651) inscriptions, so any form of the language before this date cannot be described with any degree of certainty. Moreover, as a literary language, Middle Persian is not attested until much later, to the 6th or 7th century. And from the 8th century onwards, Middle Persian gradually began yielding to New Persian, with the middle-period form only continuing in the texts of Zoroastrian tradition.
The native name of Middle Persian was Parsik or Parsig, after the name of the ethnic group of the southwest, that is, "of Pars", Old Persian Parsa, New Persian Fars. This is the origin of the name Farsi as it is today used to signify New Persian. Following the collapse of the Sassanid state, Parsik came to be applied exclusively to (either Middle or New) Persian that was written in Arabic script. From about the 9th century onwards, as Middle Persian was on the threshold of becoming New Persian, the older form of the language came to be erroneously called Pahlavi, which was actually but one of the writing systems used to render both Middle Persian as well as various other Middle Iranian languages. That writing system had previously been adopted by the Sassanids (who were Persians, i.e. from the southwest) from the preceding Arsacids (who were Parthians, i.e. from the northeast). While Rouzbeh (Abdullah Ibn al-Muqaffa, 8th century) still distinguished between Pahlavi (i.e. Parthian) and Farsi (i.e. Middle Persian), this distinction is not evident in Arab commentaries written after that date.
New Persian
The history of New Persian itself span more than 1000-1200 years. The development of the language in its last period is often considered in three stages of early, classical, and contemporary periods. The fact that almost all current native speaker of the language do understand ancient texts of Persian language and the grammatical differences of ancient language is acquainted by today speakers simply by reading and memorising those ancient texts gives a special status to Persian language as a whole.
Early New Persian
Classic Persian
The Islamic conquest of Persia marks the beginning of the new history of Persian language and literature. It saw world-notable poets and was for a long time the lingua franca of the eastern parts of Islamic world and of the Indian subcontinent. It was also the official and cultural language of many Islamic dynasties, including Samanids, Buyids, Tahirids, Ziyarids, the Mughal Empire, Timurids, Ghaznavid, Seljuq, Khwarezmids, Safavid, Afsharids, Zand, Qajar, Ottomans and also many Mughal successor states such as the Nizams etc. For example, Persian was the only oriental language known and used by Marco Polo at the Court of Kubla Khan and in his journeys through China. The heavy influence of Persian on other languages can still be witnessed across the Islamic world, especially, and it is still appreciated as a literary and prestigious language among the educated elite, especially in fields of music (for example Qawwali) and art (Persian literature). After the Arab invasion of Persia, Persian began to adopt many words from Arabic and as time went by, a few words were even taken from Altaic languages under the Mongol Empire and Turco-Persian society.
