Japanese imperative sentences are a syntactic structure that directly expresses the speaker’s demands for the listener’s actions. Common meanings include commands, wishes, negative wishes, and ironic commands. Due to the characteristics and succinctness of imperative sentences, they can effectively capture the audience’s attention in advertisements, especially in sports-related contexts, while also stimulating their motivation to act and sense of participation. In contrast, Chinese imperative sentences tend to express suggestions or requests in a gentler manner and exhibit greater structural flexibility. Through a comparative analysis of specific advertising examples and prior research, this article finds that in the context of advertisements, Japanese imperative sentences and Chinese imperative sentences are quite similar, both conveying a strong suggestion. This indicates that the semantics of Japanese imperative sentences are not limited to traditional commands, wishes, negative wishes, and ironic commands, but can also extend to broader meanings such as suggestions.展开更多
