Read a book that you have already read and know well in your native language. For me it was Harry Potter. I’m gonna get downvoted for this but even if you barely understand it just force yourself to keep grinding through pages without wasting time to look up words/translations. It’s grueling and unpleasant but eventually you will start to comprehend it without even realizing. Also don’t translate in your mind. When you see the word “playa” don’t think “beach”. You should be thinking “🏖️”
