For example, we speak today of cows, sheep, calves and hogs, all Anglo-Saxon words. Since no other foreign invader ever again set foot on English soil, the Norman invasion of the language was the last violent change in the English language. Since then the language has become more stable through the invention of printing and the advent of the dictionary. The English, like the Cajuns, have simply taken into their language whatever foreign words they find serve a useful purpose. Since almost half of the English words are of French origin, learning French is easier for someone who speaks English.
Many words are identical in spelling but differ only in pronunciation.
Not all words which are similar in spelling mean the same thing in both languages, and this has caused some embarrassment to neophyte French or English speakers. But we'll go into that some other time.
