俗ラテン語
Throughout much of western Europe, from Late Antiquity, the Vulgar Latin of everyday speech developed into locally distinctive varieties which ultimately became the Romance languages. However, after the end of Roman rule in Britain during the early 5th century, Vulgar Latin died out as an everyday spoken language. The time that Vulgar Latin died out as a vernacular in Britain, its nature and its characteristics have been points of scholarly debate in recent years.
