Was Ruth a Moabitess

Does the Book of Ruth really call Ruth a Moabitess, or as I've recently read, that she was an Israelite from Moab?

If the land north of the Arnon River was taken by Israel and occupied by Gad, Rueben and Manasseh by the time of the Judges, couldn't she have been born an Israelite?

I would appreciate any light on the subject, especially the translation from Hebrew that refers to her as a Moabite, or, "from the country of Moab".
