Final answer:
English words are derived from Latin through a history of borrowing and language influences.
Step-by-step explanation:
According to the lesson, many English words are derived from Latin. When the Romans introduced their alphabet, which was derived from the Etruscans and Greeks, into England, many Latin words began to be borrowed by the English language. For example, words like 'school' and 'Christmas' come from old Greek words with the letter chi, pronounced [k]. The spelling of the Greek words was changed to ch when borrowed into English but the pronunciation remained [k].
