Abstract
This study reports about a class for advanced students of Japanese with as topic metaphors, color terms, synaesthesia, onomatopoeia and mimesis, and polysemy, which are the field of cognitive semantics. Analyzing the use of metaphor expressions by students, 4 types are found; 1) Japanese characteristic expressions, 2) Multilingual expressions, 3) Expressions based on the way of thinking of the 1st language, and 4) Original expressions. Especially 3) and 4) demand a high level of Japanese. This study suggests 1) that some students ask to learn about metaphors in order to improve their reading skills, and 2) that students need to understand the character of the source.
