This paper uses a combination of fieldwork and questionnaires to analyse the intergenerational differences between three generations of Taihu dialects in terms of phonology, vocabulary and grammar, and to explore the factors of their formation.

The text is divided into three main sections. The introduction introduces the background and significance of the study, as well as the geographical and dialectal overview of Taihu County. It also provides an overview of the current status of previous research, specifies the research subjects and methods, and briefly introduces the survey collaborators.

The main part of the article analyses the intergenerational differences in Taihu dialect, including phonology, lexicon and grammar: (1) the expressions of variation in the vowel, rhyme and tone features of Taihu dialect are explored; (2) the expressions of variation in word form and meaning in Taihu dialect are studied, including differences in the number of syllables, differences in the morphemes of constructions, and differences in word sense expansion, transfer and colour sense; (3) the noun plural, overlap, gerundic constituents, convergent (3) analysis of variations in noun plurals, overlap, gerundive constituents, tendency, prepositions, conjunctions, interrogatives, verbal complements, modal voice and comparisons.
