The aim is for students to be able to translate with ease between two languages, usually their first or native language (L1) and the target language (L2) being learned”
My Spanish teacher used an analogy one time about how you have a file cabinet in your brain for language. She said that rather than having multiple files for multiple languages that you should think about it as having one large file that contains all your languages and to not try and think about translating a phrase or sentence from language to another. If you are trying to speak Spanish it is a lot more beneficial to fill in words that you don't know with words you do in English/other languages. She referred to this as "Spanglish" and this is a word that has stuck with me ever since.
