What does Je te presente Coralie mean?

Answer 1

Translation: I present to you, Coralie.

It is a method of personal introduction, that would be roughly equivalent to the English, "Have you met my friend, Coralie?" with her standing right next to the speaker.

Answer 2

"Je te presente Coralie litteraly" means "I am introducing Coralie to you". It would probably be phrased differently in English. "This is Coralie" or "Meet Coralie". I hope this helps!
