Thank you for the advice, but I already speak various languages. I am Frenchman and I speak fluently french and german (my mother is from Germany). I have learnt English at school.
I don't understand Spanish. It's a romance language, but quite different from french and italian (I can read). As a great fan of Monique Fuentes, I don't understand a lot (a few words that have cognates in French) when she speaks Spanish. Latin American Spanish is also very different from European Spanish, spoken in Spain.
