Verbal doubling in Mandarin Chinese, especially in lian...dou constructions, including both initial and internal verb-doubling forms, remains an underexplored area in the study of Chinese syntax. This dissertation investigates this phenomenon by addressing two key questions: (1) What triggers the movement underlying verb doubling in lian...dou constructions? and (2) What is the size of the constituent that undergoes displacement, and what insights does this provide into the mechanism of doubling?
Drawing on empirical data, the study first investigates the trigger of movement. Previous accounts that attribute doubling either to morphological fusion (Cheng & Vicente, 2013) or to a covert maximality operator (Constant & Gu, 2010) are critically evaluated as neither adequately explains the syntactic differences between initial and internal verb-doubling constructions. I propose that in internal lian...dou constructions, within the TP layer, it is the focus feature of dou that triggers movement, whereas in initial lian...dou constructions, a topic feature in the left periphery triggers movement to satisfy discourse-related licensing requirements, topicalization. Turning to the size of the displaced constituent, I challenge previous proposals of V-head or VP movement and instead argue for a vP-movement analysis, as diagnostics indicate that objects and aspectual markers can undergo fronting, and that the distribution of passive markers, modals, and negation aligns with a vP-sized constituent movement rather than a bare verb or VP movement. These results further indicate that vP, TopP, and DP function as phases in verb-doubling lian...dou constructions.
The phase-related results refine accounts of Mandarin phasehood and support the crosslinguistic view that phasehood is context-sensitive and dynamic (Bošković, 2014; den Dikken, 2007). The evidence of dual chain reduction, aligning with distributed deletion patterns reported in German (Fanselow & Ćavar, 2003) and Korean (Jung, 2005), demonstrates that verbal doubling is not purely a syntactic phenomenon but a syntax-PF interface effect. In this way, the data from Mandarin verb-doubling lian...dou constructions provide new insights into the architecture of grammar.
