German declension

The nominative, accusative, dative and genitive cases. The declension of nouns, adjectives, articles and numbers.

We know that verbs are conjugated (I eat vs. he/she eats) but it is rather simple in English; there are not many changes in the conjugation depending on the person and number.

German declension consists of adding an ending to:

• nouns
• adjectives
• pronouns
• articles
• numbers

according to the case (Fall or Kasus), gender and number.

The Idea of Case (Fall or Kasus) in German

In German there are 4 cases:

• Nominative (Nominativ)
• Accusative (Akkusativ)
• Dative (Dativ)
• Genitive (Genitiv)

Nominative

The nominative is used if

• The word is isolated:

Name*
name

*("Name" is nominative)

• If the word makes up part of the subject:

Mein Name hat 5 Buchstaben*
My name has five letters


*("Mein Name" has the function of a subject and is declined in the nominative)

• If the word forms part of the object of the predicate and the sentence is formed with the copulative verb ( sein, werden or bleiben)*

María ist mein Name*
Maria is my name


*("Ist" is part the verb "sein" (copulative) and therefore the object is declined in nominative)

Accusative

Accusative is used if:

• If the word is a direct object in English, it will be accusative in 90% of the cases in German.

Ich sagte meinen Namen*
I said my name


*("sagte" is from the verb "sagen", which is a verb that is not copulative. For that reason, it is accusative)

Depending on the verb, the objects can be accusative, dative or with a preposition. Fortunately, most cases coincide with English ones all of the time. Be careful!

• If it follows a preposition that is accusative (bis, durch, für, gegen, ohne, um, wider) or comes after a Wechselpräposition that indicates movement.

Ich gehe in die Schule*
I am going to school


*("die Schule" is declined in accusative because it follows the preposition "in" and going which indicates movement)

Dative

• If the word is part of an Indirect Object in English, it will be dative in German in some 90% of the cases.

Ich schenke dir ein Heft*
I give you a notebook


*("ein Heft" (the thing that is
given) is accusative and whom it is given to is dative)

• If it follows a preposition that is dative: "ab", "aus", "außer", "bei", "entgegen", "entsprechend", "mit", "nach", "seit", von, zu or a Wechselpräposition if it does not indicate movement.

Genitive

• If the word is after the word "of" in English

Die Zukunft des Buches ist schwer*
The future of the book is difficult


*(In English genitive’s expressed with "of" or by adding an apostrophe to show possession. "Des Buches" is translated as "of the book" or "the book’s")

• If it follows a preposition that is Genitive (anstatt, aufgrund, außerhalb, dank, statt, während, wegen)

The genitive is not used as often by Germans as the three other previous cases. Often, a noun object is made with the preposition "von" + Dative and the genitive preposition are sometimes used incorrectly as if they were dative.

You have to keep in mind that one word can fit the rules of different cases simultaneously. For example, it can be a subject while being a part of a noun object and follow a preposition that is dative. Which case would it be then? Nominative because it’s the subject, Genitive, because it’s the noun object or dative because it is after a preposition?

The answer is that the priorities are in this order:

1. Following a preposition (governing with Accusative, Dative or Genitive)
2. Being part of a genitive object (Genitive)
3. The rest of the rules
