Vulgar Latin

The original written Latin language (what is today referred to as Classical Latin) was adapted from the actual spoken language of the Latins, with some minor modifications, long before the rise of the Roman Empire. As with many languages, over time the spoken vulgar language diverged from the written language with the written language remaining somewhat static. During the classical period spoken (Vulgar) Latin still remained largely common across the Empire, some minor dialectal differences notwithstanding.

The collapse of the Western Roman Empire rapidly began to change this. The former western provinces became increasingly isolated from the Eastern Roman Empire, leading to a rapid divergence in the Latin spoken on either side. In the West an even more complex transformation was occurring. A blending of cultures was occurring between the former Roman citizens who were fluent in the proper Latin speech (which was already substantially different from Classical Latin), and the new Gothic rulers who, though largely Latinised, tended to speak Latin poorly, speaking what could be considered a creole of Latin and their Germanic mother tongue.
