Lesson 35

Negating with "Nicht" and "Kein" (Nominative & Accusative)

Recommended resources

Hallo! Willkommen zurück zu unserem Deutschkurs.

Introduction

In our last lesson, you learned how to use a specific set of prepositions—durch, für, gegen, ohne, um—that always require the accusative case. This reinforced your understanding of how and when to decline articles and pronouns.

Today, we will address a fundamental aspect of communication: negation. In English, we mostly use the word "not". German, however, makes a crucial distinction between two words: nicht and kein. Your knowledge of the nominative and accusative cases will be essential here. By the end of this lesson, you will be able to correctly negate sentences using nicht and kein, confidently applying the right endings in both nominative and accusative contexts. This will finally clarify the difference between saying "I have a dog" (Ich habe einen Hund) and "I have no dog" (Ich habe keinen Hund).

1. The Two Words for "Not": nicht vs. kein

The most important rule to learn is what each word negates.

  • kein is used to negate nouns that would otherwise have an indefinite article (ein/eine) or no article at all. Think of it as meaning "not a," "not any," or "no."
  • nicht is used to negate almost everything else: verbs, adjectives, adverbs, proper nouns, and nouns preceded by a definite article (like der, die, das) or a possessive article (like mein, dein).

To get a clear overview of this distinction, let's start with a short video.

How to say 'not' in German | nicht vs. kein

The video 'How to say 'not' in German' from mugridge language provides a great introduction to the difference between 'nicht' and 'kein' and explains why it can be tricky for English speakers.

Watch the first part of the video (from 00:00 to 03:29). Pay close attention to the helpful rule of thumb introduced at the end of the section: 'kein' is often used where you could say 'not any' or 'no' in English.

2. Negating Nouns with kein

As you just saw, kein is used to negate nouns. Think of kein as the negative version of the indefinite article ein. Just like ein changes its ending based on the gender and case of the noun, so does kein.

Let's review the declension of kein in the nominative and accusative cases, which you've already studied for ein.

Case Masculine (der) Feminine (die) Neuter (das) Plural (die)
Nominative kein keine kein keine
Accusative keinen keine kein keine

Let's see this in action:

  • Nominative (Subject of the sentence):

    • Das ist ein Tisch. (That is a table.) -> Das ist kein Tisch. (That is not a table.)
    • Das ist eine Lampe. (That is a lamp.) -> Das ist keine Lampe. (That is not a lamp.)

  • Accusative (Direct object of the sentence):

    • Ich habe einen Hund. (I have a dog.) -> Ich habe keinen Hund. (I have no dog.)
    • Ich kaufe eine Tasche. (I am buying a bag.) -> Ich kaufe keine Tasche. (I am not buying a bag.)
    • Ich sehe ein Auto. (I see a car.) -> Ich sehe kein Auto. (I see no car.)

Notice that the ending on kein perfectly matches the ending that ein would have in the same position. The masculine accusative (-en) is the most important one to master, as it's a common pattern.

To see a very clear table of these endings and more examples, please review the following resource.

NICHT vs KEIN: Master the Difference in German Negation

The article 'NICHT vs KEIN' on learn-german-easily.com has an excellent, clear table showing how 'kein' changes. This will be a great reference for you.

Scroll down to the section titled 'Examples of the German word kein in different cases'. Focus only on the tables for Nominativ and Akkusativ. Read the examples to see how the endings change depending on the gender and case of the noun.

3. Negating Everything Else with nicht

When you are not negating a noun with an indefinite/no article, you will use nicht. The rules for nicht are about placement rather than endings.

You use nicht to negate:

  • Verbs: Ich schlafe nicht. (I am not sleeping.)
  • Adjectives: Das Auto ist nicht neu. (The car is not new.)
  • Adverbs: Er fährt nicht schnell. (He doesn't drive fast.)
  • Proper Nouns: Das ist nicht Peter. (That is not Peter.)
  • Nouns with definite/possessive articles: Ich sehe den Mann nicht. (I don't see the man.)

A simple rule for placing nicht is that it often comes towards the end of the sentence. However, if you want to negate a specific part of the sentence (like an adjective or adverb), you place nicht directly before it.

  • Das Wetter ist nicht schön. (The weather is not beautiful.)
  • Wir gehen heute nicht ins Kino. (We are not going to the cinema today.)

The following worksheet provides a great visual summary of when to use nicht versus kein.

German Negation: Nicht vs. Kein Worksheet
This worksheet visually separates the uses of 'nicht' and 'kein'. On the left, verbs and actions are paired with 'nicht'. On the right, nouns (a book, a car, a bag) are paired with the correctly declined forms of 'kein' ('kein Buch', 'keinen Wagen', 'keine Tasche'), illustrating its use in negating objects.

4. Practice Makes Perfect

Now it's time to apply these rules. The best way to internalize the difference between nicht and kein is through practice.

German Negation Rules Explained: Use “Nicht” and “Kein” Correctly

The article 'German Negation Rules Explained' from Preply offers some excellent exercises to test your understanding.

Please scroll to the section titled 'Practice German negation with exercises'. Complete the exercises under 'Fill-in-the-blank' and 'Sentence transformation'. Write down your answers before checking them against the solutions provided in the article.

Here are the exercises from the article for your convenience. Try to solve them first!

Fill-in-the-blank

  1. Ich habe _____ Bruder.
  2. Sie spricht _____ Deutsch.
  3. Wir haben _____ Zeit.
  4. Das ist _____ gut.
  5. Er hat _____ Freunde.

Sentence transformation (Turn the positive sentences into negative ones)

  1. Ich habe einen Hund.
  2. Sie ist glücklich.
  3. Er trinkt Wasser.
  4. Wir gehen ins Kino.
  5. Das Kind spielt im Garten.

Once you've written down your answers, you can check them below.

Fill-in-the-blank Answers:

  1. Ich habe keinen Bruder. (Brother is masculine, and it's the direct object, so you need the accusative form keinen.)
  2. Sie spricht nicht Deutsch. (Deutsch here is treated like a concept or part of the verb phrase Deutsch sprechen, so we use nicht. You could also say Sie spricht kein Deutsch, which is also common and implies she speaks no German at all.)
  3. Wir haben keine Zeit. (Time is feminine, direct object, so accusative keine.)
  4. Das ist nicht gut. (Here, you are negating the adjective gut.)
  5. Er hat keine Freunde. (Friends is plural, direct object, so accusative keine.)

Sentence transformation Answers:

  1. Ich habe keinen Hund.
  2. Sie ist nicht glücklich.
  3. Er trinkt kein Wasser.
  4. Wir gehen nicht ins Kino.
  5. Das Kind spielt nicht im Garten.

Conclusion

Sehr gut! You have now learned one of the most important and practical grammar points in German. Mastering negation is key to expressing yourself accurately.

Key Takeaways:

  • Use kein to negate nouns that have an indefinite article (ein/eine) or no article.
  • Use nicht to negate verbs, adjectives, adverbs, proper nouns, and nouns with definite or possessive articles.
  • kein must be declined just like ein. In the accusative case, masculine nouns require keinen.

Preview of the Next Lesson:
In our next lesson, we will put everything from this module together. You'll practice using the accusative case in a variety of conversational contexts: describing what you see, what you buy, and what you want. This will involve direct objects, accusative prepositions, and, of course, negation with kein and nicht.
