The Pamir languages
 
Group Iranian (with Persian, Kurdish etc.), Southeast Iranian (with Pashto, Khwaresmian, etc.)
Geography The group of minor Iranian languages spoken in the Pamir mountains, in the border area between Tadjikistan, India, Pakistan, Afghanistan, and China. The following languages (or dialects) are usually referred to as the Pamir languages: Wakha, Ishkashimi, Yazgulami, the Shugnano-Rushani subgroup of dialects (including Shugnani, Rushani, Hufi, Bartangi, Oroshori, Sarykoli). A number of features are common between Pamir languages and two other minor dialects of the region: Munjani and Yidga, but this is still a question. 
History Pamir languages never had writing, their speakers used Tadjik or Uighur as the language of official communication. Europeans got acquainted with them only in the late 19th century, and even today they are not studies enough to say for sure if they are a group of close relatives or a language unity which emerged in the Pamir mountains. 
Phonetics The phonetic systme varies in different tongues, but everywhere it shows more long vowels (u, o, i, e) than short (u, i). As for the consonants, the Pamir languages lack laryngeals and faryngeals. Some of the languages developed a system of three grades of stops: normal (k), labiovelar (kw) and palatal (k') just as it was in the Proto-Indo-European language. 
Nominal Morphology Only a few of the Pamir languages decline their nouns; some of them have definite article which can be declined, or have postfixes and prepositions to mark the case and the number. Some of Pamir tongues also preserve the gender. The pronouns have kept a number of original Indo-European traits, personal pronouns exist only for the 1st and the 2nd person, demonstrative pronouns have 3 grades ('this' - 'that' - 'that distant'). 
Verbal Morphology The verbs of the Pamir languages have 2 types of stems: present and past (derived from the old participle in -ta, -na). The personal forms are flective in the present tense, but enclitic in the past. The Munjani language has developed a new secondary system of inflections from agglutinative suffixes.
Lexicon The vocabulary of Pamir languages seems rather archaic, having plenty of terms for different nature objects and lack of modern terminology. New words are formed with the help of suffixes.
Writing No writing
Close Contacts Pashto is the closest relative; Tadjik has influenced much the lexicon of Pamir tongues, as well as the Uighur language (for the Sarykoli language).
