I am a student in secondary school and like others i seem to always have trouble on which prepositions i should you use. Do you have any tips/guidelines for me ?
Really, they should be learned with the verb. They're very similar to phrasal verbs in English (blow, versus blow up, etc.) and it's best to just learn what verb + prep mean together. Unfortunately, I don't know of a list on the internet that details all of them.
