Building on previous studies on Qiang,this paper aims to identify the type of prosodic word in Qiang and argues that prosodic morphology plays a crucial role in determining the shape of morphology.This paper arrives at two significant conclusions:1)Similar to Mandarin Chinese and the Jingpo language,Qiang is characteristic of disyllabic prosodic morphology,highlighting the"syl-lable counting"nature of the Sino-Tibetan family.2)Disyllabic prosodic words are crucial factors that play an important role in shaping morphology.The results of a series of morphological phenomena,such as compound words,contraction words,and complementary words are influlenced by prosodic words.
