The French language was developed from the vernacular Latin of the Roman Empire, and is divided into three historic and linguistic periods: Old French, which developed before the 14th century; Middle French, which was used between the 14th and 16th centuries; and Modern French, which was used after the 16th century and continues to be in use today. During all of these periods, the French language was heavily influenced by other languages.
For example, Old French was infused with Germanic words and sounds when barbarian tribes invaded and settled in France after the fall of the Roman Empire. Middle French also borrowed heavily from the Italian language during the Renaissance. The close proximity of both Germany and Italy also allowed for a great transmigration of linguistic and cultural practices.
