one point about period French: the final consonant was pronounced when the word was standing alone. This is the opposite of how French is taught today -- that the final consonant is not pronounced unless it comes before a word beginning with a vowel. Historically, the principle was that it IS pronounced, except when it comes before a word that starts with a consonant.

Also, the French pronunciation of a word like "moi" was more like "mway", and the English pronunciation of the same sorta rhymes with our modern word "why," except drawn out more so you can almost hear the separate parts of the diphthong.
