Abstract: Retroflexation in Yuanshi Dialect are featured with the fusion of ［·］(ER)with retroflex and lateral sound(opened-mouth, closed-mouth),changing them into ［k⌒］, ［k‘⌒］, ［x⌒］ and ［］,respectively,or make them syllabized consonants. Besides,［］, ［‘］, ［］ and ［l］ may also be found rhotacized into ［k⌒］, ［k‘⌒］, ［x⌒］ with different levels of velarization and ［］ in the south of Hebei province. Complex consonants such as ［k⌒］, ［k‘⌒］, ［x⌒］ and ［k⌒］, ［k⌒‘］, ［x⌒］ are double-site “velar-retroflex”,whose different strength of velar and retroflex shows a relationship that is bi-directional opposite and continuous change. Furthermore, those complex consonants correspond with ［］,［］,the rhotacized form of［］, ［l］,demonstrating a kind of parallelism in their departing and joining. All these features,especially the correlation between syllablization and ［-］ coda,as well as the correlation between stability of syllablization and opened-mouth,closed-mouth, have significance in understanding the cause and process of this kind of complex consonants and syllabized consonants.

Key words: Yuanshi Dialect, rhotacized initial, complex consonant, syllabized consonant, typological comparison
