Relevance theory is a communicative theory put forward by Sperber and Wilson, and it is regarded as an ostensive-inferential process. According to Relevance Theory, the context of discourse is "a subset of the premise of understanding, the psychological structure and the listener's assumptions about the world". In the process of translation, in order to avoid word-for-word translation, adaptation is needed, which is the main point of relevance-adaptation theory. Relevance theory and relevance adaptation theory have strong explanatory power to translation.

Context in relevance theory;

Sperber and Wilson's Relevance Theory (200 1) regards language communication as an ostensive-inferential process, and puts forward that language communication is a cognitive activity according to certain inference rules from a cognitive perspective. Therefore, we should study translation from the perspective of relevance. In Relevance Theory, the receiver of communication makes contextual assumptions based on the clarity of the communicator, relying on three kinds of information in cognitive context: logical information, encyclopedic information and lexical information. Context is a series of assumptions that exist in people's minds in order to understand the discourse correctly during the interaction between the two parties. Because people's cognitive environment and cognitive structure are different, discourse understanding may produce different implied conclusions. From the cognitive point of view, context is the knowledge produced in the process of dynamic reasoning.
