I'd often hear the word Second Brain and the word English Brain on the YouTube videos. and the method of making of it might be that above all excluding mother tongue might be inevitable. people who became fluent like as native and who was born to be bilingual might have utterly different way of translating from language learner. in the case of translation that English sentence would be translated into Mother tongue(MT) they wouldn't translate it directly into MT word to word. they would depict precise image/feeling on their brain. they would put this image/feeling to the thinking way of MT. they don't use MT in their brain at all. so their translation wouldn't become word to word direct-translation.
