Here's a simplified timeline:
* 1st Century AD: Latin is introduced to Gaul as the language of the Roman Empire.
* 5th Century AD: The Roman Empire collapses, and Gaul is divided into various kingdoms. Latin starts evolving into different dialects.
* 8th Century AD: The Frankish kingdom emerges, and a dialect called "Frankish" becomes dominant.
* 10th Century AD: The term "Langue d'Oil" (meaning "oil language") is used to refer to the language spoken in northern France, while "Langue d'Oc" (meaning "yes language") refers to the language spoken in southern France.
* 12th Century AD: The Langue d'Oil begins to standardize, influenced by the literature of the French court.
* 14th Century AD: French becomes the official language of France.
So, while the origin of French lies in Roman Latin, it evolved and developed throughout various regions of France over many centuries.
