Cases
German has four grammatical cases (der Fall or der Kasus in German): nominative, accusative, dative, and genitive. A case alters a noun, pronoun, adjective, etc., in some way to mark its grammatical function in a phrase, clause, or sentence. For example, the main function of the nominative (der Nominativ) case is to mark the subject in a sentence:
Ich liebe die deutsche Sprache!
In this sentence, the pronoun ich represents the first person subject and is in the nominative case. Every noun, pronoun, adjective, etc. has form in every case and it is very important to learn all of them. For example, the accusative form of ich is mich:
Die deutsche Sprache liebt mich!
