How do the cases in German work?
Could someone explain to me the proper way to use cases and give me sentence examples?
all nouns, along with their adjectives and determiners/articles use one of four cases, depending on their function in the sentence.
All verbs have a set of rules how many subjects/objects you can attach to it and which cases are used for those. You'll have to learn those rules along with the verbs eventually, but you can use this as a guideline:
For the subject (and after the verb "sein"), use the nominative case.
For direct objects, use the accusative case.
For indirect objects, use the dative case.
For indication of possession or affiliation, use the genitive case.
