Kabiye (kàbɪ̀jɛ̀; also rendered Kabiyé, Kabiyè, Kabye, Kabyé, Kabyè, Cabrai or Cabrais) is an Eastern Gurunsi Gur language spoken primarily in northern Togo. Throughout the 20th century, there was extensive migration to the centre and south of Togo and also to Ghana and Benin. Kabiye speakers made up over 23% of the Togolese population in 1999. Kabiye is one of two national languages of Togo (along with Ewe). In the Togolese context, national language currently means that the language is promoted in national media and, in the formal education sector, as an optional exam subject in grades 9 and 10. The missionary-linguist Jacques Delord published the first descriptive grammar of Kabiye in 1976. This was followed by Kezié Lébikaza's descriptive grammar in 1999, which remains the key reference work in Kabiye linguistics. There is also a Kabiye-French dictionary. Other topics that have been the focus of research include: Comparative linguistics, Discourse analysis, Language contact, Lexicology, Morphology, Phonology, Sociolinguistics, Syntax, Tone orthography, Tonology, and the verb system. The earliest known publications in Kabiye appeared in the 1930s. Altogether there have been about 200 publications in Kabiye, though not all of these are still in print or easily available for purchase. For an inventory up to the turn of the century see Pouwili, 1999. Publications include two books of proverbs, folktales, poetry, medical booklets, agricultural booklets, translations of the Bible, political tracts, religious tracts, a short novel, primers, and other pedagogical materials. The Kabiye Wikipedia was initiated in June 2014 by Gnasse Atinèdi, the secretary of the Académie Kabiye. It currently (July 2017) has 1185 articles on a wide range of international subjects. The five voiced consonant sounds /b v dʒ ɡ ɡ͡b/ only occur either word-medially or as allophones. The retroflex sound /ʈ/ can occur as voiced allophones of [ɖ], [ɽ], or [r] in medial position. The long back unrounded vowels only occur at morpheme boundaries.
