What is the difference between metonymy and metaphor?

Metonymy, as its name implies, is to borrow one thing to replace another, so most of them are nouns. When using it, we must consider the legitimacy and universality of substitution, and try not to simplify the complex and make the meaning smooth. Moreover, metonymy at this time is generally similar to seeing the big from the small, seeing the big from the small and seeing the big from the small, and concretizing the sentence image. Generally speaking, metonymy is a kind of words or characters that do not directly say what they want to express. But to borrow the rhetorical methods of people or things closely related to it. What is replaced is called ontology, and what is replaced is called borrowing. Ontology does not appear, instead it is borrowed. The difference between metonymy and metonymy is that metonymy is similar to metonymy, which replaces one thing with another, but its nature is completely different. Metonymy means that there is a generation in metaphor, and metonymy is a generation rather than a generation. Metonymy focuses on similarity and metonymy focuses on relevance; Metonymy can become a simile, but metonymy can't. There is a real relationship between metonymy's ontology and borrowing body. Generally speaking, this relationship is still relatively close. The noumenon and vehicle of metonymy are essentially different things, but people connect them through association according to their similarity. The category is 1. Metonymy is figurative metonymy. The semantic relationship between its original meaning and borrowing meaning is similar. 2. Metonymy, that is, non-figurative metonymy. The semantic relationship between the original meaning and the borrowed meaning is not similar, but other relations. Some generations have used them all in a representative way. As the sun sets, fish scales rise and fall. (Thanks for the center) Use fish scales instead of fish. Feature-generated ontology means that the name of ontology is replaced by the characteristics and signs of body (person or thing). For example, a standard was used to kill Yamaraja. (meiling three chapters) It is a symbol, and the army or armed forces are replaced by a standard. For example, the compass is very uneven. Americans don't know what Washington is like (Lu Xun's hometown) replaced Yang Er's sister-in-law with a "compass" with thin feet. The concrete abstraction is as follows: 1. 1 (meiling three chapters) The "beacon smoke" in the case was originally a firework used for ancient border guard, which means here. The abstract concept of war has been concretized and visualized. Tools represent ontologies, such as 1. In the season of scaring farming, eight out of ten households have set fire to their hoard and can't open the pot. In the example 1, "hoarding" is a tool for holding grain, and "igniting hoarding" means lack of grain; "Pot" is a tool for cooking. If you can't boil the pot, you have no food. Proper name generation generally refers to replacing the name of ontology with the special name of a typical person or thing. For example: 1. If you kill an Li Gongpu, millions of people in Li Gongpu will stand up! (The Last Speech) The second "Li Gongpu" in example 1 refers to a person who is not afraid of bloodshed and sacrifices, but fights for democracy and peace. For example, people laugh because they cover their stomachs, and laugh because there are jokes or funny things. The result of "laughing" was replaced by funny reasons such as "jokes". The image replaces the ontology, for example, above.
