Vulgar Latin is what is often referred to as a “common” form of Latin or one that commoners would use in everyday life. This form of Latin would have been spoken in the Roman Republic and Empire. In this definition of Vulgar Latin, this can refer to any Latin being used by the population of Ancient Rome regardless of the time period. Vulgar Latin can also be used to refer to the type of Latin used in the later Roman Empire, around the 3rd century CE. This type of Latin is often found in Christian texts, Roman inscriptions, and medical and grammatical texts. Typically, any written Latin from the Roman early Empire and Republic would not have been written in Vulgar Latin.  Vulgar Latin is often marked by the loss of certain forms and spellings of classical terms or even the preference for vocabulary terms that are less prominently used in Classical Latin. Additionally, Vulgar Latin tends to focus more on using prepositions rather than utilising cases. This makes it easier to learn, provided you know the definitions of the prepositions. Classical Latin evolved from Old Latin. This form of Latin would have been used among the educated individuals of Ancient Rome from the Republic to the middle Roman Empire in both speech and writing. This form of Latin will be found in any Republican or Imperial speeches, literature, and inscriptions. Classical Latin is considered by many to be the standard form of Latin with other forms of Latin being corruptions of it. Compared to later types of Latin, Classical Latin focuses greatly on case usage to identify the use of nouns and adjectives within sentences.
