The Kurdish languages (Kurdî or کوردی) are several Iranian languages spoken by the Kurds in western Asia. The Kurdish languages are not mutually intelligible unless there has been considerable prior contact between their speakers. There is debate over whether the languages spoken by Kurds form a group linguistically.
The literary output in Kurdish language was mostly confined to poetry until the early 20th century, when a more general literature began to be developed. In its written form today, Kurdish has two dialects, namely Kurmanji in the northern parts of the geographical region of Kurdistan, and Sorani further east and south. The second official language of Iraq, referred to simply as 'Kurdish' in political documents, is Sorani, whereas the recognized minority language in Armenia is Kurmanji, which is also spoken in Turkey, Syria, Iraq, and Iran. Another group of languages, Zaza–Gorani, is spoken by several million Kurds. Hewrami, a dialect of Gorani, was an important literary language since the fourteenth century but was replaced by Sorani in the twentieth. (Wikipedia)
