Better - and necessary for my use case - is the first word. I just type whatever I want and it suggests/tries both languages at the same time. Few words is too late since I want to use 1-3 words in the other language only.

That's generally exactly how it works for me. I don't think I've done anything special with my configuration apart from enabling two different language keyboards.
