I was referring to my own language skills. Knowing that English is 40% French gives you an opportunity to translate much of French into English, but it is far from being able to speak it fluently. You may read French in such a way and get a lot of info, but that's all. To speak it or understand it spoken, you need to know more than language history. That goes for both English and French, as both differs in pronunciation from the written language.
