How do you write i have eaten in french?

The phrase "I have eaten" in French depends on the context:

If you want to say "I have eaten" in the sense of "I have already eaten," the correct translation is:

* J'ai mangé. (pronounced: "jay man-jay")

If you want to say "I have eaten" in the sense of "I have eaten something specific," you would use:

* J'ai mangé [food]. (pronounced: "jay man-jay [food]")

For example:

* J'ai mangé un sandwich. (I have eaten a sandwich.)

* J'ai mangé des pâtes. (I have eaten pasta.)

Remember that in French, you need to conjugate the verb "manger" (to eat) according to the subject pronoun.
