How do I use prepositions at the end of sentences and questions? I've watched many videos about it and I still have troubles with that. I understand that's a informal way to use prepositions, or some verbs are obligatorily followed by prepositions but in my native language (Portuguese) I can't do that, it doesn't make any sense in Portuguese. So if I read a sentence like "Because what you want you dream of" I can understand but probably I wouldn't say it in this way, I'd look for anoher way to say the same thing but that it wouldn't be necessary to use preposition at the end. Definately I don't want it, I want to speak English as close as possible to an English native speaker. Is there any method to learn them easily or only practice makes perfect?
