The four principles of Naida's theory of functional equivalence

Lexical equivalence, syntactic equivalence, chapter equivalence, and stylistic equivalence.

1, lexical equivalence: the meaning of a word lies in its usage in the language, and the corresponding lexical meaning is found in the target language.

2. Syntactic equivalence: the translator should not only be clear about whether the target language has such a structure, but also understand how often it is used.

3, chapter equivalence: when doing discourse analysis, one should not only analyze the language itself, but also see how the language embodies the meaning and function in a particular context.

4. Stylistic equivalence: the translator should correctly understand the stylistic style of the original text and use the most appropriate stylistic style to express it in the translation.
