Genitiv — the possessive case

The fourth and final case. It marks ownership and relationships — the book of the student, the capital of Germany. In modern speech, Germans increasingly replace Genitiv with von + Dativ, but in writing and formal speech it's alive and well. You need it.

The question that finds it

Ask wessen? of a noun. The answer is Genitiv.

Articles

Masculine and neuter share -es. Feminine and plural share -er. Same two-vs-two split you've seen before.

The noun changes too — masculine/neuter Genitiv

Here's the only case where the NOUN itself picks up an ending: masculine and neuter singular nouns add -s or -es in Genitiv.

• One-syllable nouns usually add -es: des Mannes, des Kindes, des Hauses.
• Multi-syllable nouns usually add -s: des Vaters, des Autors.
• Feminine and plural nouns DON'T change.

Proper names — just add -s

For names (people, places — even shop names), just bolt -s on without an apostrophe. This is the ONE place German normally uses word-order-free ownership: the owner comes FIRST.

For names ending in -s, -z, -x, German often uses an apostrophe only to signal the missing -s: Thomas' Buch, Fritz' Idee. Rare but worth recognizing.

Word order inside the phrase

The normal order is noun + Genitiv modifier, which is the reverse of English:

• das Auto meines Vaters (literally: "the car of-my-father")
• die Freundin des Lehrers ("the girlfriend of-the-teacher")

The owned thing comes first; the owner in Genitiv follows. With proper names, word order inverts (Peters Auto), but this is the only exception.

Genitiv prepositions (preview)

A small fixed list of prepositions takes Genitiv. You'll meet the full list next lesson. For now: wegen, während, trotz, statt.

The speech workaround: von + Dativ

In casual spoken German, especially with simple possession, speakers often prefer von + Dativ.

Both are correct German. In formal writing, stick with Genitiv. In conversation, you'll hear both — and von + Dativ is actually more common with simple structures.

Adjective endings in Genitiv

After a Genitiv article, the adjective takes the weak ending -en. All four genders, all four cells: always -en.

That's a gift — no decision-making needed. Genitiv + adjective = -en.

Common mistakes, named

1. Forgetting the -s on masculine/neuter nouns. Das Auto des Mann. ❌ → des Mannes. ✓

2. Using an apostrophe with names. Peter's Auto. ❌ → Peters Auto. ✓ German generally doesn't use an apostrophe for possessives (except after -s/-z/-x names).

3. Putting the owned thing second. Meines Vaters Auto is grammatically OK but sounds old-fashioned. Modern German prefers das Auto meines Vaters.

4. Using Genitiv where von + Dativ fits better in speech. For simple conversational ownership, von is more natural. Save Genitiv for writing or longer phrases.

There's a quirky group of masculine nouns that adds -n or -en in EVERY case except Nominativ singular. You'll notice it once and use it forever: the N-Deklination.
