Dialects
The Dari language has traditionally been divided into two main dialects: the variety spoken in Yazd and the one spoken in Kerman. This division of the language, based on the division of its speakers into their two main cities of residence, conceals the complexity of the actual dialectical situation. The Yazdi dialect itself has some thirty varieties, each distinct and unique to one of the Zoroastrian neighborhoods in and around Yazd. The variation amongst the Yazdi dialects is so great that, were they not for their geographic proximity, they would no doubt be classified as distinct dialects. The Kermani dialect may also contain (or may have contained at one time) a comparable level of dialectical complexity.
