It is a Germanic language that is derived from German. Lexiconically English did pick up a ton of French, and a good deal of Spanish at least for American-English (not sure about British-English given America has much common "cowboy jargon" that is directly taken from Spanish), but we still have a ton of words in English that are still very similar, if not nearly identical, to their German counterparts, our verbs conjugate and function much in the same way (such as -ed being the common weak verb ending in both languages), and we even have similar cases, although English speakers (again, at least in America) tend to not utilize them or depend on them as much as Germans.
