Metonymy and metonymy are similar and easy to be confused, but they are different. Similarities: metonymy and metonymy are both substitution, metonymy is to replace ontology with metonymy, metonymy is to replace ontology with metaphor, and ontology does not appear. Difference: 1. Metonymy metonymy is an objective thing. This thing is related to ontology, and the basis of metonymy is the association between borrowing and ontology. There is no metaphorical relationship between the two, and the focus is on reference. The vehicle in metonymy has nothing to do with objective reality. The basis of metonymy is the similarity between ontology and vehicle, which is a metaphor in borrowing and focuses on "metaphor".
2. Metonymy cannot become simile or metaphor, but metonymy can become simile and metaphor. Metonymy and metonymy can be distinguished by forming similes. Understand the ontology, if you can add "image" to form a simile, it is a metaphor; On the contrary, metonymy.
3. Rhetorical effects are different. Metonymy focuses on the aesthetic feeling of images, and metonymy reveals the characteristics of things through relevant associations, thus achieving the purpose of rendering the atmosphere and containing feelings in images.
