The Indo-Iranian branch
of Indo-European languages is one of the oldest languages for which
we have historical records. Vedic hymns date back to 1000 BC, and
Classical Sanskrit appears around 500 BC. The Indo-Europeans who
settled in the Iranian Plateau developed the sacred language Avestan.
Avestan is the sister branch of Old Persian. The Avestan speakers
are the ancestors of modern Persian speakers.
Indo-European languages
can be classified as satem and centum languages. Satem
is the Avestan (an ancient Iranian language) word for "hundred";
centum is the Latin word for "hundred". This classification
is based on the development of the Indo-European palatal k.
For more information
on the classification of Indo-European languages, see Pyles and
Algeo, "The Origins
and Development of the English Language", page 66.
The Indo-European palatal
k (as in *kmtóm "hundred")
is a distinct phoneme from velar k (as in the verbal
root *kwer- "do, make"). The asterisk (*) indicates
a transcription of Indo-European.
Example: karma
is a Sanskrit loanword that has the velar k.
Satem languages
include Indo-Iranian, Balto-Slavic, Armenian, and Albanian. Thus,
the satem branch also includes Farsi, Pashto, Dari, Kurdish, Baluchi,
and a number of other languages and dialects. In satem languages,
the two sounds for k remain separate phonemes, and
the palatal k becomes a sibilant.
Example: Sanskrit satam,
Lithuanian imtas, Old Church Slavic suto.
In contrast, in other
Indo-European languages, the two sounds for k become
a single phoneme.
Example: In the Germanic
group, palatal k shifts to h, as in
Greek (he)katon, and Old English hund.
Old Persian
Old Persian phonetics
are represented by three pairs of monophthongs (long and short a,
i, u), diphthongs (ai,
au), and 23 consonant phonemes. The morphology shows
seven or eight cases, three numbers, three genders, verbs had very
complicated structure.
The vocabulary of Old
Persian borrowed plenty of words from other ancient Iranian languages,
and also from non-Indo-European tongues such as Aramaic (Semitic).

Middle Persian
Middle Persian was the
language of the Sassanian Empire (AD 224-641). Middle Persian grammar
is more simplified in comparison to Old Persian. It was usually
written in an ambiguous script with multivalent letters, adopted
from Aramaic. After the Arab conquest in the 7th century, use of
Middle Persian declined. A lot of Middle Persian literature was
translated into Arabic, but the bulk of it was lost during Islamic
times.
Middle Persian phonetics
changed greatly. For example, Indo-European g'h (which
became z in Old Persian) now turned into d;
s > h, kw > sp > s. Parthian and other neighbour
languages such as Arabic influenced these changes. The morphology
now becomes completely analytic, loses genders and cases, many verbal
forms.

Modern Persian
Modern Persian was developed
by the 9th century. It is a continuation of an area-wide standard
language that had considerable Parthian and Middle Persian elements,
with additional influences from other Iranian languages. It is written
in a Perso-Arabic script (an expanded version of Arabic script).
Modern Persian grammar
is simpler in comparison to Middle Persian. It has absorbed a vast
Arabic vocabulary. There are no gender and noun cases; nouns only
have categories of definiteness and number. The definite article
-í is used post-positively (after the noun).
All Modern Persian verbs are conjugated following the same type,
and can be simple or complex.

Iranic sub-branches
Iranic sub-branch speakers
have distinguished their speech from the Indic sub-branch by raising
and fronting the larynx and tongue precluding voiced aspiration.
Example: *bh >
b, *dh > d, *jh > j, *gh > g. Indo-European transcriptions
are indicated with an asterisk (*).
Also, they further accentuated
lingual fronting by "prognathizing" (jutting out the jaw)
while keeping the tip of the tongue against the lower teeth. This
caused dentalization of the earlier palatal affricates.
Example: Indo-European
palatal stops * ky > *c > [Proto-Iranian] *ç;
* gy > *j > [Proto-Iranian] * z.
In addition, they restrained
the occlusion of s until only the accompanying glottal
turbulence remained, unless the s preceded a stop
consonant.
Example: *s >
h.
Later, they restrained
the occlusion of stops before other consonantal sounds, changing
dental affricates and voiceless aspirated stops to spirants (*ç
[ts] > s [Old Persian þ], *z [dz] > z
[but Old Persian d], *ph > f, *th > þ, *kh > x)
and producing spirants before consonants (*pt > ft, *pr
> fr, etc.).

South-Western Iranian
Languages
The South-Western Iranian
languages center on the southern Zagros Mountains and Fars in south-western
Iran. Persian, the most influential of them, spread from there in
ancient times under the Achaemenian and Sassanian empires, through
Iran and northern Afghanistan as far as Central Asia and Tajikistan.
South-Western Iranian
speakers distinguished themselves through a progressive strengthening
of consonantal occlusion, increasing acoustic noise through voiceless
spirancy or voiced plosion, with occlusive strengthening probably
caused by increased prognathizing.
Example: Old Persian
*ç [ts] > þ [a voiceless dental spirant],
*z [dz] > d, *dv >
d.
Modern Persian dialects
of Afghanistan preserve the eight-vowel system of early Modern Persian,
which is reduced to six vowels in Iran and Tajikistan. Dialects
of Iran show an accentual tendency toward lingual fronting, while
in Tajikistan lingual backing with lip rounding is an accentual
feature; thus a in Afghan Persian becomes [æ]
in Iran, while â ([å]) in
Iran and Afghanistan becomes o in Tajiki. Within Persian,
polarization appears as fronted lingual accent in Iran versus backed
lingual accent in Tajikistan.
