Gender, articles & two cases: Every German noun has a gender — masculine (der), feminine (die) or neuter (das) — and you learn the noun with its article: der Tisch, die Lampe, das Buch. The article also shows the noun's case, the job it does in the sentence. This micro covers the first two cases: the Nominativ (the subject — who/what does the action) and the Akkusativ (the direct object — who/what the action falls on).
das Genus / das Geschlecht
grammatical gender — masculine, feminine or neuter
der bestimmte Artikel
the definite article — der / die / das ('the')
der unbestimmte Artikel
the indefinite article — ein / eine ('a/an')
der Nominativ (Nom.)
nominative case — the SUBJECT (who/what does the action)
der Akkusativ (Akk.)
accusative case — the DIRECT OBJECT (who/what receives the action)
das Subjekt
subject — the doer of the verb (stands in the Nominative)
das Objekt
object — the noun the action falls on (here, the direct object → Accusative)
Why it matters: Getting der/die/das and the Nom./Akk. right is the single biggest accuracy win in German. Examiners reward it under Criterion A (Language). The good news: only one form actually changes between the two cases — the masculine der → den (and ein → einen).

Three genders, two cases — only one form changes: Learn the article table below. The key insight: between Nominativ and Akkusativ, feminine, neuter and plural do NOT change — only the masculine changes: der → den and ein → einen. So if you master that one shift, you have the whole table.
GenusNominativ (Subjekt)Akkusativ (Objekt)
maskulin (der Mann)der / einden / einen
feminin (die Frau)die / einedie / eine
neutrum (das Kind)das / eindas / ein
Plural (die Leute)die / —die / —

Die Endung beim Verb (the verb between subject and object)

  • Subject in the Nominative — «Der Hund schläft.» (The dog is sleeping.)
  • Direct object in the Accusative — «Ich sehe den Hund.» (I see the dog — der → den.)
  • Feminine stays the same — «Die Katze schläft.» → «Ich sehe die Katze.»
  • Neuter stays the same — «Das Buch liegt da.» → «Ich lese das Buch.»
  • Indefinite article — «Ein Mann wartet.» → «Ich sehe einen Mann.» (ein → einen).
  • Negation 'kein' follows ein — «Ich habe keinen Hund.» (masc. Akk. → keinen).
Masculine is the only one that moves: Repeat the rule until it's automatic: der → den, ein → einen, kein → keinen — but die, das and the plural die look the same in the Nominative and the Accusative. Spotting which noun is masculine is the whole game.

Find the subject, find the object: To pick the right case, ask two questions. Who/what does the verb? → that noun is the subject → Nominative. Who/what does the action fall on? → that noun is the direct object → Accusative. Most simple sentences are Subject + Verb + Object, e.g. «Der Junge isst den Apfel».

Wann Nominativ, wann Akkusativ

  • Subject of the verb → Nominativ — «Die Lehrerin erklärt die Grammatik.» (The teacher explains the grammar.)
  • Direct object of the verb → Akkusativ — «Ich kaufe einen Computer.» (I'm buying a computer.)
  • After the verb 'sein' (to be) it STAYS Nominativ — «Das ist ein guter Freund.» (That's a good friend.)
  • Many everyday verbs take an Accusative object — haben, sehen, kaufen, essen, trinken, lesen, brauchen.
  • Time phrases use the Accusative too — «Ich bleibe einen Monat in Wien.» (I'm staying a month in Vienna.)
'sein' keeps the Nominative: A common trap: after sein (to be) and werden (to become) the noun stays Nominativ, not Accusative — «Er ist ein Lehrer», never «einen Lehrer». These verbs link two things that are the same, so both are subjects.
A dialogue, line by line: Here's a short conversation built one exchange at a time. Watch the article: the subject stays in the Nominative, and a masculine direct object switches der → den / ein → einen while feminine and neuter stay put. Read it for meaning, then tap Übersetzung anzeigen for the English or 🔊 to hear it.

Nominativ und Akkusativ in Aktion

Ein Dialog, Zeile für Zeile

  1. —Wer kauft das Brot? —Der Vater kauft das Brot.
  2. —Und was kauft er noch? —Er kauft auch einen Apfel und eine Tomate.
  3. —Sieht der Junge den Hund? —Ja, der Junge sieht den Hund im Park.
  4. —Liest die Lehrerin das Buch? —Ja, sie liest das Buch laut vor.
  5. —Trägt der Mann die Tasche? —Ja, der Mann trägt die Tasche und einen Koffer.
Steal this for your writing: Notice the pattern: the doer takes der/die/das, and a masculine thing being acted on becomes den/einen. When you write, name the subject first, then check: is my object masculine? If yes, switch to den/einen — that one habit fixes most case errors.

The slips to watch for: Almost every case error here is one of three things: leaving the masculine object as 'der' instead of «den», changing a feminine/neuter article that should stay the same, or forgetting that 'sein' keeps the Nominative. Compare the right version with the typical mistake and the fix becomes obvious.

Richtig

  • Ich sehe den Film heute Abend.
  • Sie liest das Buch.
  • Er ist ein guter Schüler.

Häufiger Fehler

  • Ich sehe der Film heute Abend.
  • Sie liest den Buch.
  • Er ist einen guten Schüler.
Gender / object / sein: Run a quick three-point check: What gender is the noun? Is it the subject or the object? And is the verb 'sein/werden'? Only a masculine object of an action verb changes (der→den, ein→einen); everything else keeps its Nominative article.
