Have you ever learned a foreign language, and if so, which one?

[Juliuscaesar]

I've learned German, though I still have to review the grammar rules from time to time, and I know a little Dutch.I would like to learn French, but I prefer Germanic languages since English is a West Germanic language.Maybe I could learn Old Frankish perhaps at a University one day, but I don't know if there is enough written material as there is in Old English to study.
