The Old Persian language is one of the two attested Old Iranian languages (besides Avestan). Old Persian appears primarily in the inscriptions, clay tablets, seals of the Achaemenid era (c. 600 BCE to 300 BCE). Examples of Old Persian have been found in what is now present-day Iran, Iraq, Turkey and Egypt the most important attestation by far being the contents of the Behistun inscription (dated to 525 BCE).

Classification

Old Persian is an Old Iranian language and a member of the Southwestern Iranian language group. As an Iranian language, Old Persian is also a member of the Indo-Iranian branch of the Indo-European language family. Avestan, the only other attested Old Iranian language, does not belong to the same geographic division as Old Persian and is typologically distinct.

Language evolution

By the 4th century, the late Achaemenid period, the inscriptions of Artaxerxes II and Artaxerxes III differ enough from the language of Darius' inscriptions to be called a "pre-Middle Persian," or "post-Old Persian." Old Persian subsequently evolved into Middle Persian, which is in turn the nominal ancestor of New Persian.
Professor Gilbert Lazard, a famous Iranologist and the author of the book Persian Grammar states:

The language known as New Persian, which usually is called at this period (early Islamic times) by the name of 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. Unlike the other languages and dialects, ancient and modern, of the Iranian group such as Avestan, Parthian, Soghdian, Kurdish, Pashto, etc., Old Middle and New Persian represent one and the same language at three states of its history. It had its origin in Fars and is differentiated by dialectical features, still easily recognizable from the dialect prevailing in north-western and eastern Iran.

Middle Persian, also sometimes called Pahlavi is a direct continuation of old Persian, and was used as the written official language of the country Ulrich Ammon, Norbert Dittmar, Klaus J. Mattheier, Peter Trudgill, "Sociolinguistics Hsk 3/3 Series Volume 3 of Sociolinguistics: An International Handbook of the Science of Language and Society", Walter de Gruyter, 2006. 2nd edition. pg 1912: "Middle Persian, also called Pahlavi is a direct continuation of old Persian, and was used as the written official language of the country." "However, after the Moslem conquest and the collapse of the Sassanids, Arabic became the dominant language of the country and Pahlavi lost its importance, and was gradually replaced by Dari, a variety of Middle Persian, with considerable loan elements from Arabic and Parthian.". After the Muslim conquest, modern Persian also called Dari, which was a variety of Middle Persian with considerable loan elements from Iranian Parthian and semitic Arabic supplanted Middle Persian.

Consequently, Modern Persian is one of the few Indo-European languages which has extant writing in its old, middle and modern form. Comparison of the evoluation at each stage of the language shows great simplification in grammar and syntax. In fact according to available documents, Persian language is an Iranian language all whose three Old, Middle, and New stages are known to represent one and the same language; in other words New Persian is a direct descendent of Middle and Old Persian.

Substrates

Old Persian "presumably" has a Median language substrate. The Median element is readily identifiable because it did not share in the developments that were peculiar to Old Persian. Median forms "are found only in personal or geographical names [...] and some are typically from religious vocabulary and so could in principle also be influenced by Avestan." "Sometimes, both Median and Old Persian forms are found, which gave Old Persian a somewhat confusing and inconsistent look: 'horse,' for instance, is [attested in Old Persian as] both asa (OPers.) and aspa (Med.)."

Script

Old Persian was written from left to right in the syllabic Old Persian cuneiform script. The Old Persian cuneiform contains 36 signs representing vowels and consonants, 8 logograms, and 3 signs which can be combined to represent any numeral, although only a few numbers are actually attested in the inscriptions.
