Metonymy is a rhetorical device, which means that you don't directly say the name of the thing you want to say, but call it by the name of another thing related to it. Metonymy, as its name implies, is to borrow one thing to replace another, so most of the borrowed pronouns are nouns. When using it, we should consider the legitimacy and universality of substitution, try to simplify the complexity and make the meaning smooth.
Metonymy at this time is generally similar to seeing the big from the small and seeing the big from the small, reflecting the big situation or situation and making the sentence more vivid and concrete. Generally speaking, metonymy is a rhetorical method of borrowing people or things closely related to metonymy when speaking or writing articles, rather than directly saying what you want to express.
Traditional rhetoric defines metonymy as a figure of speech that temporarily replaces the original person or thing with relevant person or thing according to the needs of rhetoric, which is called metonymy; Logical thinking defines metonymy as a temporary replacement between adjacent concepts in the same conceptual domain. This definition is based on the cognition of the psychological basis of metonymy, and it is a more rational definition of metonymy.
Compared with the traditional definition, this definition still contains three factors: relevance, timeliness, ontology and substitution of borrowing. The concept can be a noun concept, a verb concept or an adjective concept. Using "concept" instead of "name" makes up for the shortcoming that the traditional definition is easily misunderstood as metonymy is only a substitution between nouns.
The difference between metaphor and ridicule;
Metonymy and metonymy are similar, they both replace one thing with another, but they are completely different in nature. Metonymy means that there are generations in metaphor, and metonymy is generations rather than self-evident; Metonymy focuses on similarity and metonymy focuses on relevance; Metonymy can become a simile, but metonymy cannot.
There is a real relationship between metonymy ontology and metonymy. 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.
