Medieval French resembled Latin language.
Latin is a classical language which belongs to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets as well as from the Phoenician alphabet.
Latin was spoken in the area surrounding Rome, called Latium. Through the power of the Roman Republic, it became the dominant language, originally in Italy and subsequently throughout the western Roman Empire. Vulgar Latin developed into the Romance languages including Italian, French, Portuguese, Romanian, and Spanish.
