The coordinating conjunction"Haiyou(还有)"can be classified into a NP-Conjunction"Haiyou 1"and a S-Conjunction"Haiyou2"in modern Chinese.Both,emerging in the Ming Dynasty,have evolved from discourse usage to connecting components,but with no evolutionary links.The existential clause"Haiyou NP"with repeated meaning complements the object of the main clause in the discourse,forming a parallel structure of"NP+VP+NP,Haiyou NP".After the integration of"Haiyou NP"into the main clause,"NP Haiyou NP"became the object of"VP"and"Haiyou"was reanalyzed as a NP-Conjunction.The possessive clause"(speaker)Haiyou XP"with repeated meaning was in the transitional position of the discourse,where it generated the function of connecting and appending.After the loss of its subject,"Haiyou XP"was idiomatized as discourse markers.These markers lost"XP"and then S-Conjunction"Hai you"emerged.
