When is French inverted?

Hello, when can I use French inversion?

1, when leading a direct speech, the subject and verb should be reversed-jepense, dit la nurse, qu 'il y a encore de soup. The nurse said, I think there is still some soup. I'm not hungry, I replied.

2. In interrogative sentences, when the subject is a noun or a person's name, the subject remains the same, but the third person pronouns (il, elle, ils, elles) and verbs of the same sex and number should be used to form an inversion.

3. Supplementary explanation: In French learning, you will find that we don't often use this sentence pattern, but adopt the form of "interrogative adverb est-ce que+ narrative sentence", but in fact, inverted sentences will make sentences more formal.

In these cases, it can be inverted, and inversion is just a style. 1) after relative pronouns, 2) after comparative degrees, and 3) emphasizing the subject, especially in poetry.
