Nominativ — the subject case

This is lesson 1 of your German path. If you learn only one case well, make it this one. Every German sentence has a Nominativ. It's the starting line every other case runs from.

The one question Nominativ answers

Nominativ is the case of the subject — the person or thing that does the verb. You find it by asking the verb a question:

Wer? (who?) — for people Was? (what?) — for things

Take a sentence and ask it. Whatever answers is the Nominativ.

That's the whole test. If a word answers wer? or was? for the verb, it's in Nominativ.

Why it looks easy (and the trap inside)

The Nominativ is the form you see in dictionaries. Hund, Frau, Kind, Autos. That's why English speakers often feel like they already know it — and why they then trip over Akkusativ and Dativ later. The trick is to notice the Nominativ as a case, not as "the default form of the word." Once you see it as one of four cases, the other three stop feeling like exceptions.

The thing that actually changes between cases isn't the noun — it's the article in front of it (der, die, das, ein, eine). So Nominativ is really a story about four small words.

The four forms you have to know

Every German noun has a grammatical gender: masculine, feminine, neuter, or plural. In Nominativ, the definite article ("the") takes these shapes:

A few things worth burning in:

• der is masculine, die is feminine, das is neuter. This is the skeleton of the whole German article system. Every case is a variation on this.
• die does double duty — it's feminine singular and plural. That's not a glitch; it's just how the language is built.
• There's no indefinite plural. "A dog" is ein Hund, but "dogs" is just Hunde. Where English would say "no dogs," German uses keine (keine Hunde).
• ein appears twice (masculine and neuter). They look identical in Nominativ; they diverge in Akkusativ and Dativ. Nominativ hides this.

A working example, thought through

Let's watch a sentence get built, noun by noun.

Ein Mann kauft einen Apfel. A man is buying an apple.

Two nouns: Mann and Apfel. Which one is Nominativ?

Ask the verb: Wer kauft? Who is buying? Ein Mann. So Mann is Nominativ — that's why the article is ein and not einen. The apple is being acted on, not doing the buying, so it's in Akkusativ (we'll get to that next lesson — note the einen).

Now the same sentence with the subject in plural:

Kinder kaufen einen Apfel. Children are buying an apple.

Wer kauft? Kinder. So Kinder is Nominativ, plural. There's no article — as we just said, indefinite plural has no form. You could add die to specify "the children," giving Die Kinder kaufen einen Apfel. Same Nominativ, just definite now.

The verb gives the Nominativ away

You don't actually need to hunt for the subject. The verb points at it. In German, the verb agrees with the Nominativ noun the way it does in English:

If you ever lose track of what's Nominativ in a longer sentence, find the conjugated verb and ask wer? or was?. Whatever the verb is conjugated for, that's your Nominativ.

After "to be", things get weird (in a good way)

One quirk worth learning on day one: the verb sein ("to be") and a few others (werden, bleiben) don't take an object. They take another Nominativ. The thing on both sides of sein is Nominativ.

If you've studied Spanish, this is like ser + noun. German calls this a predicate nominative, and it's the number one reason beginners say einen when they should say ein. Watch for sein and friends — they reset the rule.

Common mistakes, named

1. Saying "einen" after ist. Das ist einen Hund. ❌ → Das ist ein Hund. ✓ After sein, the noun stays in Nominativ. ein, not einen.

2. Treating the first word as the subject. Den Apfel esse ich. — "Den Apfel" is first, but it's Akkusativ (the thing being eaten). ich is the subject. German word order lets you front anything for emphasis; that doesn't make it Nominativ.

3. Forgetting plural = die. Der Kinder spielen. ❌ → Die Kinder spielen. ✓ Plural in Nominativ is always die, whatever gender the singular was.

4. Remembering "a" as just ein. "A woman" is eine Frau. "A car" is ein Auto. Gender changes the article even with "a/an."

Mini check

Where this leads

Nominativ is the floor. The next three cases all branch off the same four-article skeleton — they just change what those articles become when the noun is getting acted on (Akkusativ), receiving something (Dativ), or possessing something (Genitiv).

Once der/die/das/die feels automatic in Nominativ, you've already done 40% of the work for every other case.

Next up: Akkusativ — the case for direct objects. The one place Nominativ and Akkusativ actually diverge (spoiler: only masculine changes) is where half of all beginner errors happen. We'll walk into that deliberately.
