The “V1OV2 de” construction is a commonly used colloquial expression in modern standard Chinese and a typical construct. This study explores the grammatical and semantic features and the reasons for its formation from a construct grammar perspective. The research found that “V1OV2 de” is a non-typical verb-copying construction, and its meaning of constructioncan be summarized as “explaining the reason why an event has taken place in a certain
situation.” This construction is driven by cognitive economy and formed based on a typical verb-copying construction through operations such as transposition, deletion, and substitution. Linguistic and non-linguistic reasons work jointly to contribute to the production and use of the “V1OV2 de” construction.
