THÌ and LÀ Constructions in Vietnamese: A Study on Argument Structures

This study aims to shed light on the argument structure of the Vietnamese particles THÌ and LÀ, which function as markers of focused constituents and topic-comment structures, respectively. The research objectives are to identify the syntactic and semantic properties of constructions involving THÌ and LÀ, and to analyze their argument structures within the theoretical frameworks of construction grammar. Specifically, the constructional approach (Goldberg 1995, 2006) and radical construction grammar (Croft 2001) will be employed. The methodology involves collecting a corpus of naturally occurring data from various written sources. The data will undergo qualitative analysis to identify argument structure patterns associated with THÌ and LÀ constructions, as well as quantitative analysis of frequency and distribution. The expected findings will provide insights into the argument structures of these Vietnamese constructions, elucidating how focused constituents and topic-comment structures are marked. The study will evaluate the applicability of the chosen theoretical frameworks in accounting for the observed patterns. The findings have potential applications in natural language processing tasks requiring accurate recognition and interpretation of focused constituents and topic-comment structures, such as information extraction, machine translation, and language generation. Furthermore, the study may inform language teaching and acquisition by shedding light on the usage patterns of THÌ and LÀ in Vietnamese. The analysis is expected to contribute to a deeper understanding of argument structures in Vietnamese and potentially motivate extensions or modifications to the theoretical frameworks.
