Influence of English language by Roman Language:
Latin influenced the English language both directly and indirectly but the major lasting influence is indirect. The biggest indirect influence occurred after the Normans invaded England. Normans spoke French a descended from Latin which was deemed a romance language. In addition, the old English borrowed some terms from Latin and that is the direct influence.
Another notable influence is in science and academia; most terms are in Latin language and they remained unchanged until today. Also during the Norman and Roman invasion, Latin was the language used by the Roman Catholic Church; the only Christian Church at that time.
