本文选取魏晋南北朝、唐、宋、元、明、清和现代汉语具有代表性的口语材料为语料,综合儿缀分布、意义、功能的表现,将儿缀的发展分为五个时期,即萌芽期、成型期、成熟期、发展期和衰变期。以此为序,理清儿缀的发展历程,勾勒出儿缀演变轨迹,并着眼于语言内部和外部因素解释儿缀发展的特殊性,为儿缀发展受语言接触影响这一假设提供证据。语言接触的影响和语言使用者的能动作用极大地推动了儿缀的演变进程,使它在韵律功能的方向上迈出了一大步。 This paper chooses the typical oral materials in the Wei, Jin, Southern and Northern Dynasties, Tang, Song, Yuan, Ming, Qing and modern Chinese as the corpus, synthesizes the distribution of children, meaning and function, divides the development of children’s adornments into five periods Period, forming period, maturity, development and decay period. Taking this as a starting point, we can clarify the development history of infantile infants, outline the evolution trajectory of infantile infants, and explain the particularity of the development of infantile infants in terms of the internal and external factors of the language and provide evidence for the hypothesis that the development of infants is affected by the language contact. The impact of language contact and the active role of language users have greatly facilitated the evolution of children’s infants, making it a major step in the direction of prosodic function.
