"I am doing very well, thanks."
The last item was a bit of a challenge, at least if you stuck around for the "For the curious..." part. So we're going to take it easy in the next two, building on what we already know. Our first phrase is "I am doing very well, thanks." Here we go:
Spanish Yo estoy muy bien, gracias = "I am very well, thanks."
Italian Io sto molto bene, grazie = "I stand very well, thanks."
French Je vais très bien, merci = "I am going very well, thanks."
All the words are arranged according to the keywords I've given, and in the right order. Piece of cake.
