Say i want to come with you in french?

Here are a few ways to say "I want to come with you" in French, with slightly different nuances:

Formal:

* J'aimerais venir avec vous. (I would like to come with you.)

* Je souhaiterais venir avec vous. (I would wish to come with you.)

Informal:

* J'aimerais bien venir avec toi. (I would really like to come with you.)

* J'aimerais beaucoup venir avec toi. (I would really love to come with you.)

* Je veux venir avec toi. (I want to come with you.)

More casual:

* On y va ensemble? (Shall we go together?)

The best choice will depend on the context and your relationship with the person you are talking to.
