Abstract: About the source of partical "Ta(他)Ge(个)", some scholars think it comes from the grammaticalization of "Ta(他)Yi(一)Ge(个)" in double-objects "V +他(indirect object) + (一)个+ N (P) (direct object)", but we think this conclusion is yet to be.From the diachronic evolution of language, the source of partical "Ta(他)Ge(个)"is not single, but diversified, that it actually comes from the solidification and the grammaticalization of "Ta+Yi/Zhe/Nage(他+一/这/那个)" in the leading property structure, double referential structure and the double-objects. In other words, The final formation of partical "Ta(他)Ge(个)" is the result of the diachronic integration of these three structures.
