| Tetrasyllable is a common language unit in Chinese.It is a language unit formed by the combination of four syllables.It is different from general temporary combinations.This combination is a relatively fixed format,so it is called " tetrasyllable"."This kind of language phenomenon is also very common in Northeast dialect.This article chooses the tetrasyllable of Northeast dialect as the research object,and discusses its structure type,semantic features and production mechanism on the basis of existing research.The Northeast dialect is relatively close to Mandarin.Compared with the dialects in other regions,the research on the Northeast dialect is not thorough and comprehensive,and there are still some problems that we need to solve.In recent years,some scholars have studied the language units of Chinese starting with the number of syllables,so this article attempts to analyze the four-phonetic structure of the Northeast dialect from the perspective of prosodic grammar.From the perspective of the relationship between the number of syllables and the information to be conveyed,the more syllables,the more information conveyed,and the more it can attract the attention of listeners in communication.The 2+2 prosodic structure of the tetrasyllable of Northeast dialect is authoritative in rhythm,and it can even suppress the influence of syntax and semantics on the rhythm of the prosodic structure. |
