German Declension, Step by Step

There are subtle intricacies in German that convey as much information as the words spoken or written.

Declension is an integral part of the German language, subtly telling you the role of each word within a sentence. 

If you’ve ever wondered why sometimes der Hund (the dog) sometimes turns into den or dem Hund, what those funny endings are on the end of adjectives are, and why there are so many different pronouns in German, then keep reading!

In this article, we’ll discuss what declension means for the German language, what sorts of characteristics to pay attention to when using declension, and what steps you need to follow to ensure you use declension properly.


What Is Declension?

In the context of German grammar, declension means providing essential information about the nouns in a sentence and how they relate to each other. This involves making the case, number and gender of a noun clear. 

Think of it this way. When you speak in English about a noun, you somehow have to denote how many you are talking about. The sentence “Mary fed the ducks” tells you there’s more than one duck.

At the same time, the sentence structure—most importantly here, the verb—tells us who or what the subject is and who or what the direct object is. Mary is our subject, as she feeds the ducks, and since she is performing the action—feeding, which the hungry ducks receive happily–the ducks act as our direct object.

English mostly relies on word order to convey this information. We know that Mary is doing the feeding because she comes before the verb. However, German instead relies on declension, meaning the words before nouns will change in order to show both who is doing the action, and who is receiving it.

Let’s look at two sentences: 

Der Mann füttert den Hund. 

Den Hund füttert der Mann. 

Both of these sentences mean “The man feeds the dog.” But even though the second example puts the dog at the beginning of the sentence, we know that the dog is the one being fed because of the article denThis is what we call putting a noun in a different case. 

The article den also tells us that noun Hund is a masculine, singular noun. 

This is what we mean by declension, changing the words before nouns in order to convey information about the noun and what it is doing in the sentence. 

To summarize: The ability to break down a sentence into its various parts will be key to German declension—who is doing what to whom, and what is the gender and number of each noun. So remember, focus on case, gender and number!

Why Learn Declension in German?

German grammar is all about knowing what’s going on in the sentence and being able to pick out the various parts.

Knowing the declension patterns in German helps you memorize the genders that correspond to different nouns, which is necessary when you need to include adjective endings.

Memorizing not only the (1) case, (2) gender and (3) number of a noun, but also the corresponding grammar rules for denoting these three aspects, is crucial to understanding, speaking and writing German. 

In other words, understanding declension will push your German skills from simple stock phrases to whatever wonderful things you may want to say! 

How to Learn German Declension

These three aspects are crucial to understanding proper German declension.

Let’s look at some tips to help you learn all three. After that, we’ll help you put declension into practice.

1. Determining a noun’s case

The case of a German noun is usually determined by the context of the sentence and where the action is directed.

When nouns occur as the subject, they are in the nominative. This means there are no changes and every word is just as you’ll find it in the dictionary. For example:

Der Mann schwimmt schnell.
(The man swims fast.)

Er schwimmt schnell.
(He swims fast.)

Direct objects that are on the receiving end of an action take the accusative case. For example: 

Ich sehe den Mann. 
(I see the man.)

Ich sehen ihn.
(I see him.)

Notice how der Mann has become den Mann, showing that the man is on the receiving end of the verb “to see”. 

The dative case denotes indirect objects and takes it one step further. The dative usually shows the receiver of the direct object. Here’s an example:

Der Mann gibt der Frau ein Geschenk.
(The man gives the woman a present.)

Der Mann is the subject—nominative case—because he’s doing the action, and the verb geben is conjugated accordingly. Our direct object is ein Geschenk, because that is what is being given; it’s in the accusative case.

Lastly, der Frau is our indirect object. The woman is receiving the direct object, the present, so she goes in the dative case. This changes die Frau to der Frau

The genitive case shows possession. It’s a bit more complex in terms of use and being able to identify it, but let’s look at an example:

Das Haus meiner Eltern ist sehr alt.
(Literal translation: The house of my parents is very old.)

In English, we would phrase this as: “My parents’ house is very old.”

German word order aside, the important part here is the word “of.” Look at the English sentence above: The apostrophe and “s” attached to “parents” denotes possession, but in German, the genitive case is used instead.

2. Determining a noun’s gender

The best way to determine a noun’s gender is to use a dictionary or an app. Plain and simple. Memorization is best for nouns you’ll use often in everyday speech, but if you’re unsure, always consult a dictionary.

There are also many great resources and tricks for memorizing what sorts of nouns take a specific gender. For example, nouns ending in –keit and -heit are almost always feminine.

There are other characteristics in German that make it easy to guess which nouns take what gender without looking it up.

3. Determining a noun’s number

Singular nouns will always be conjugated to the er / sie / es  form of whichever verb occurs in the sentence.

However, plural nouns will always use the infinitive form of the verb. If you’re unsure about the number in regards to the subject, look first at the verb.

If you’re still in doubt, look up the form of the noun to double check. Nouns will nearly always change in spelling to reflect a quantity higher than one.

Keep these contextual cues in mind when you are writing German sentences, and work through each sentence to determine proper:

(1) case

(2) gender

(3) number

After you’ve determined which gender and case are necessary, and the number of things you’re dealing with, use the following steps to correctly write your complete German sentence.

How to Use Declension in German

Definite Articles: Der Words


Der words show definitively that you are speaking about someone or something specific, like “the man” or “the tree,” and not just “a man” or “any tree.”

You might say, “I like the tree, but a man told me it was not for sale.” Depending on context, readers should know what tree is being referred to, but “a man” is too vague to figure out who the man is, or which one is being referred to. Therefore, the “a” in “a man” is an indefinite article—more about that below.

You might also consider the difference between definite and indefinite in context of particularity: that tree (definite) vs. any tree (indefinite).

Indefinite Articles: Ein Words


We spoke about “a man” and “a tree,” and for those instances in German, we use ein words. Let’s go through each case again, this time for ein.

Just like for der words, it’s easiest to memorize the strings of articles for each case. However, indefinite articles don’t apply to plural. After all, you can’t have “a ducks”! Keep this in mind as you practice.

Plural Possessives


Another great thing about indefinite articles is that we use the same endings for the possessive—just add an “m” to the start and you’ll be ready to go. In this case, though, we do need the plural form; these are the correct plural possessives.

Nouns Without Articles


What if a noun isn’t preceded by an article, but an adjective instead? Do we still have to include the article?

The answer is complex. In fact, this is the best illustration of the purpose of declension. When you don’t know anything about the noun in the sentence, the declension will have all the clues necessary.

In short, just as in English, we don’t always include an article before the noun, but in German you do have to somehow denote (1) case, (2) gender and (3) number.

Sentences like “Broken glass covered the floor,” or “Please buy me some red potatoes” or even “I would like hot chocolate!” are all instances where the nouns mentioned do not have a definite or indefinite article attached. In these cases, the adjective before the noun fulfils this role. 

For instance, the last example sentence, in German, would read:

Ich möchte heiße Schokolade!

Die Schokolade is our noun here, and since the chocolate is being acted on by Ich, we need to use the accusative feminine ending for heiß, which is -e.
