Pomak language (Greek: πομακική γλώσσα, pomakiki glosa or πομακικά, pomakika, Bulgarian: помашки език, pomaški ezik, Turkish: Pomakça) is a term used in Greece and Turkey to refer to some of the Rup dialects of the Bulgarian language spoken by the Pomaks in Western Thrace in Greece and Eastern Thrace in Turkey. These dialects are native also in Bulgaria, and are classified as part of the Smolyan subdialect. Some grammatical forms of the Rup dialects, published by the Danish linguist Pedersen in 1907, have striking resemblance to the grammatical forms of the Armenian language. As well, the Rup dialects have slightly different forms of demonstrative suffixes (exercising also functions of the possessive pronouns) from the Bulgarian Tran dialect and the modern standard Macedonian language. There are publications concerning the vocabulary of the Rup dialects and anthroponyms of Armenian origin which overlap areas, populated by Paulicians from the 15th to 18th centuries.
According to an alternative opinion, the Pomak language is an original Slavic language with many dialects.
According to the 1935 census in Turkey, 3881 people in Eastern Thrace identified their mother tongue as Bulgarian and 18 382 as Pomak. The overall statistic from 1935 shows that 41 041 people speak Pomak as their mother tongue or as a secondary dialect.
The Pomak language was used mainly in oral communication. Currently in the formation of the literary standard Pomaks attempts to create script based on both the Greek and Latin alphabets. Recently, the Pomak Institute has published an alphabet with 29 letters for the Pomak language.
