Learning prepositions is a famous nightmare for English learners. The problem is that often there is no direct translation from English to your own first language (especially true for Greek speakers but also many other non-Latin based languages). You have to just get used to what the right preposition sounds like in the same way all English-speaking children do when they are learning to speak. That means using your ears and voice as much as your eyes. I’ve created a page with everything you need to learn, practice and stop bad habits you have with English Prepositions. As you work through the exercises remember to SAY THE SENTENCES OUT LOUD.
