認知語意學替不同語言多義詞的語意關係提供了精闢的解釋。中文裡「出」字使用頻率高（中研院平衡語料庫出現近三萬次），語意類型多樣（國語日報字典中列舉十多個意義），卻鮮少人研究。本研究以認知語意學的角度出發，利用圖像模組 (image schema) 建立中文多義詞「出」的語意框架 (semantic frame)，認為不同的觀點 (perspective) 可分析「出」字的不同語意，並以語意的譬喻延伸 (metaphorical extension) 將不同範疇的語意連結起來，解釋「出」字語意的多樣性。 / This study aims to explore the meaning relatedness of the Mandarin polysemous word chu from a cognitive approach. Theories of cognitive semantics provide a plausible account for polysemous words since a cognitive approach in analyzing language benefits the discovery of conceptual frameworks underlying complex linguistic expressions. To add another piece of empirical evidence, this study aims to examine the Mandarin polysemous word chu, which is highly productive and which exhibits extreme complexity in terms of its senses. An image schema for chu is proposed as its semantic framework and different perspectives are considered to account for the multiple senses of chu. Furthermore, metaphorical extension is detectable in the meaning shifts of chu as well.
