How do you say my favorite subject is in french?

The most natural way to say "My favorite subject is..." in French is:

"Mon sujet préféré est..."

Here's how to break it down:

* Mon: My

* sujet: subject

* préféré: favorite (masculine)

* est: is

You would then follow this with the name of your favorite subject, for example:

* Mon sujet préféré est les mathématiques. (My favorite subject is math.)

* Mon sujet préféré est l'histoire. (My favorite subject is history.)

Note: If the subject is feminine, you would use "préférée" instead of "préféré":

* Mon sujet préférée est la littérature. (My favorite subject is literature.)
