Isn't English a Germanic language though?

Yes, it is a Germanic language. The title is a tongue-in-cheek jibe about how much the English language has borrowed from French and Latin. I believe the majority of English words come from Latin/French although the top 100 most spoken words are generally Germanic. People seem to forget that England was ruled by French speaking people for a long time, and that had a huge impact on the development of the English we speak today.
