My German teachers say that before speaking or writing German, one must think in German. As far as I have observed my mind, I normally think in English. So, before speaking or writing German or Japanese, I might think in German or Japanese without realizing it. I think it’s better tht way, because if I realize it, then I’ll start thinking in English again. Then, I’ll have to translate the whole thing in German and this process will take ages….. But, even so, how do you tell your brain to think in a particular language? I totally agree with the fact that one must think in a certain language before speaking that language, but how does the brain think in a particular language without the person noticing it?
