Negation: nicht vs. kein

In English, one little word—not—handles almost every negative sentence, whether you are negating a verb, an adjective, or a noun. German divides that job cleanly between two distinct words: kein and nicht. Mixing them up (or putting nicht right before the verb like English don’t) is one of the earliest habits to fix at A1.

The split between kein and nicht becomes effortless once you look at what follows: kein is a negative article built only for indefinite or bare nouns, while nicht negates verbs, adjectives, adverbs, definite nouns, and entire clauses.

1. Using ‘kein’ (Negative Article)

Use kein exclusively to negate nouns in two situations:

1. Nouns preceded by an indefinite article (ein / eine):
   • Ich habe ein Auto (das Auto). → Ich habe kein Auto. (I don’t have a car.)
   • Das ist eine gute Idee (die Idee). → Das ist keine gute Idee. (That is not a good idea.)
2. Nouns with no article at all (uncountable nouns, general substances, abstract concepts, and indefinite plurals):
   • Wir haben Zeit (die Zeit). → Wir haben keine Zeit. (We have no time / We don’t have time.)
   • Er isst Fleisch (das Fleisch). → Er isst kein Fleisch. (He doesn’t eat meat.)
   • Ich sehe Fehler (der Fehler, pl.). → Ich sehe keine Fehler. (I don’t see any mistakes.)

How ‘kein’ Declines

Kein declines identically to the indefinite article ein in the singular and like possessive articles (mein, dein) in the plural (see Noun Gender & Articles for the base article grid).

Because die Zeit is feminine and takes the accusative after haben, Ich habe Zeit becomes Ich habe keine Zeit. Because der Kaffee (coffee) is masculine, Ich trinke Kaffee becomes Ich trinke keinen Kaffee.

2. Using ‘nicht’

Use nicht to negate everything else: actions, whole statements, definite nouns, pronouns, adjectives, adverbs, and prepositional phrases. The key question with nicht is placement, which depends on whether you are negating the whole sentence or contrasting one specific piece.

Whole-Sentence (Neutral) Negation

When negating the entire statement neutrally, nicht moves toward the end of the clause—after the conjugated verb, pronouns, time adverbs, and definite noun objects, yet before whatever closes the German sentence bracket (Satzklammer):

Notice the rule inside Word Order & The V2 Rule: the conjugated verb stays in Position 2, and the rest of the verb cluster (infinitive, past participle, or separable prefix like an) anchors the far end. Nicht always sits just in front of that closing verb element (nicht kommen, nicht gesehen, nicht an).

Contrast (Partial Negation)

If you only want to negate one specific word or phrase—especially when correcting someone with sondern (but rather)—place nicht directly before the negated element:

• Ich kenne nicht den Chef, sondern seine Assistentin (die Assistentin). — I don’t know the boss, (I know) his assistant.
• Das ist nicht mein Buch (das Buch). — That is not my book (it’s someone else’s).
• Wir fahren nicht heute, sondern morgen. — We aren’t traveling today, but tomorrow.

Adjectives, Adverbs, and Prepositional Phrases

When negating a single adjective, adverb, or prepositional destination, nicht directly precedes that element:

• Das Wetter ist nicht schön. — The weather is not nice.
• Er fährt nicht schnell. — He doesn’t drive fast.
• Wir fahren nicht nach Berlin. — We are not going to Berlin.

Double Negatives and Special Negation Words

Standard German does not use double negatives to intensify a statement; two negatives cancel each other out. Instead of stacking nicht with another negative word, swap nicht for the matching negative indefinite word (covered further in Indefinite Pronouns):

Common Mistakes (Wrong vs. Right)

Keep the division of labor clear: ein/bare noun → kein; definite noun, verb, adjective, adverb, or prepositional phrase → nicht.
