Vulgar Latin

Vulgar Latin, or Common Latin, is one of the two types of Latin. Latin is an old language that was spoken by the Romans. Vulgar Latin is not spoken anymore, but its many dialects eventually became what are now Romance languages (such as Italian, Spanish, French, Portuguese, and Romanian). Vulgar Latin was spoken by the regular people ("vulgus" in Latin means "common"): farmers, workers and those without a great deal of education.
Origin.
Classical Latin is the type of Latin that was first spoken by the Romans. As time went by, fewer and fewer people spoke Classical Latin, and in the end the language changed to become Vulgar Latin. After a while, only scholars spoke Classical Latin. Books were still written in it. While Latin is no longer spoken as a native language, many educational institutions teach it as a second language, and many Roman Catholic Church officials are fluent in it.
