I'm really curious now. If you don't mind me asking, how did you learn the meanings of the keywords when they were in a language you didn't understand? Did you have to learn to translate "for", "while", etc into Russian equivalents?
Context. I don't know what lingua franka means, but I also know what it means. I could bother and find literal translation, but why would I? The same applies to obscure English words, weird programming language keywords or math symbols. Integral and differential symbols don't really translate into anything and we use the word "integral" only because we can't type this symbol on an average keyboard.
