nicht und kein — Two Ways to Say No

🚫 nicht und kein — Two Ways to Say No

German has two main ways to make something negative. nicht negates a verb, an adjective or a whole sentence; kein negates a noun (it replaces ein). Add the possessives — mein, dein, sein and the rest — and you can say exactly whose things are whose. Getting these right shows the examiner you can do more than string single words together.

nicht vs kein — Which negative?

The first decision in any German negative is simple: are you negating a noun, or something else? A noun takes kein; everything else takes nicht.

💡 Exam Tips & Common Errors

  • Quick test: if the word you want to negate would take ein (or no article at all), use kein. Otherwise use nicht.
  • Watch the endings — in the accusative, masculine nouns make kein and the possessives end in -en: keinen Hund, meinen Bruder.
  • Be careful with sein (his) versus ihr (her) — they are a common source of marks lost in writing tasks.
  • Use a possessive plus a negative in one sentence to show range: Ich habe keine Zeit für meine Freunde.

❌ Common error: Ich habe nicht einen Hund.

✓ Correct: Ich habe keinen Hund.

Why it costs marks: to negate a noun introduced by ein, German uses kein, never nicht ein. Ich habe keinen Hund (I have no dog / I don't have a dog) is correct; nicht einen is a calque from English and is marked down as an AO2 grammar error.
