Inversion in French

What you are asking is the inversion of interrogative sentences (the inversion of subject and predicate)

This sentence asks the whole question, which is equivalent to the Chinese word "horse"

The principle is that the subject is a noun and the plural is inverted.

Subject is pronoun or on, simple inversion

-Mary Esther.-Elle Etien? Mariest (+elle) é tudiante noun subject, repeated with subject pronouns consistent with the subject number after est.

-Are you a student? Just turn it upside down.
