Negation:
nicht and kein

nicht vs kein — the core rule

English speakers learning German face an immediate problem: English has one negation word — "not" — and it goes in one predictable place (right after "be" or with "do"). German has two negation words that work differently from each other and differently from English "not." The good news: the decision between them follows one clear rule.

kein — forms, genders, cases

kein is not just one word — it changes form based on the gender of the noun it negates and the grammatical case. It follows the same pattern as ein/eine. If you know how ein changes, you already know how kein changes.

The highlighted cell is the only change: masculine accusative adds –en → keinen.

When you negate a profession or identity after sein (to be), use kein — even though there is no article in the positive sentence. German treats profession nouns after sein as if they had an indefinite article.

nicht — what it negates

nicht is the general negation word. It negates everything that is not a noun with an indefinite or no article: verbs, predicative adjectives, adverbs, proper nouns, and also definite articles (the, this). Learn the categories and the position rule will follow naturally.

Position of nicht in the sentence

The biggest nicht question after "which word?" is "where does it go?" Unlike English "not" which sits immediately after the auxiliary verb, German nicht moves around depending on what it is negating. There are three clear positions to learn.

When you want to negate the entire sentence (the whole action or event), nicht goes to the end of the clause — after all other elements.

When the sentence has sein + a predicative adjective, nicht goes directly before that adjective. Because the adjective is already at the end, nicht ends up near the end too — but it comes before the adjective, not after.

When you want to negate a specific word or phrase — not the whole sentence — nicht goes directly before the element it negates. Whatever word comes immediately after nicht is what is being denied.

The English trap and exam tips

English-speaking learners make two very predictable negation errors. The first is using nicht where kein is needed. The second is placing nicht in the English position — immediately after the verb — instead of near the end. Both errors appear in every A1 exam script from learners who have not studied this module.

English: "I do not have a car" → Word-for-word German: "Ich habe nicht ein Auto" — WRONG. When the positive sentence uses ein/eine, you must replace it with kein. You cannot keep the article and add nicht before it.

These are actually correct because sein + adjective puts nicht before the adjective (near the end), and "Ich komme nicht" has nicht at the very end. The only wrong pattern is subject + verb + nicht when the verb is NOT sein: "Ich arbeite nicht heute" ✓ (nicht before heute) vs "Ich nicht arbeite" ✗ (subject–verb split).
