Arbu一词并非如通常所认为的那样,指某一操用突厥语部落的名称,而所谓“n方言”为“西突厥 族”及回鹘人语言的观点亦不能成立。Arbu一词为地域名称,专指怛逻私和巴拉沙衮之间的广大地区。所谓 “n方言”也便是“阿尔乌语”(Arbut ε),是生活在这一地区的突厥化了的粟特人等所操的混化型的突厥语方言。 The term Arbu does not refer to the name of a certain Turkic speaking tribe, as it is generally believed, and the notion of “n dialect” as a “Western Turkic” or Hui language can not be established. The term Arbu is a geographical name that refers specifically to the vast area between Tachai and Balashaba. The so-called “n dialect” is also “Arbut ε”, a Turkic dialect spoken by Turks who lived in this area, such as the Sogdians.
