話題是被說明的對象,一般位於句首。漢語的句法結構中語序對句法成分的決定作用比較顯著,通過話題化充當話題的成分的句法位置往往會發生變化。而維吾爾語的形態發達,其語序比較自由,通過話題化充當話題的成分往往以原有形式直接移到句首充當話題。

The topic is the description of the object,generally located in the beginning of sentences. In Chinese,the word order has an important role in syntactic structure,and the syntactic positions of ingredients acting as a topic are often changed through topicalization. While in Uyghur,the morphological changes of words play an important role in syntactic structure,and the syntactic positions of ingredients acting as a topic are not changed through topicalization.
