English forms almost all of its plurals by adding -s: one cat, two cats; one book, two books. German has no such single rule. Instead, a German noun can form its plural in one of five different ways, and many plurals also change the stem vowel by adding an umlaut (a → ä, o → ö, u → ü). This page gives you the whole landscape at once so the per-pattern pages that follow have a frame to hang on.
The good news: the patterns are not random noise. They correlate strongly with a noun's gender and its ending, so once you know those, you can predict the plural most of the time.
The one fact that never changes: the article is always die
Whatever the singular gender, the plural definite article in the nominative is always die. Masculine der, feminine die, neuter das — all three collapse to die in the plural.
der Tisch → die Tische
the table → the tables (masculine becomes die)
das Buch → die Bücher
the book → the books (neuter becomes die)
die Lampe → die Lampen
the lamp → the lamps (feminine stays die)
The five patterns at a glance
Here is one clean example of each pattern, plus one example that adds an umlaut, so you can see all the moving parts together.
| Pattern | Singular | Plural | Umlaut? | Typical gender |
|---|---|---|---|---|
| -e | der Tag | die Tage | no | masculine, neuter |
| -e + umlaut | der Stuhl | die Stühle | yes (u → ü) | masculine, feminine |
| -er | das Kind | die Kinder | no (no back vowel) | neuter, few masc. |
| -er + umlaut | das Buch | die Bücher | yes (u → ü) | neuter, few masc. |
| -(e)n | die Frau | die Frauen | never | feminine, weak masc. |
| -s | das Auto | die Autos | never | loanwords, all genders |
| zero (no ending) | der Lehrer | die Lehrer | sometimes | masc./neut. in -er, -el, -en |
| zero + umlaut | der Apfel | die Äpfel | yes (a → ä) | masc./neut. in -er, -el, -en |
Wir bleiben nur ein paar Tage.
We're only staying a few days.
Die Kinder spielen draußen im Garten.
The children are playing outside in the garden.
Ich habe zwei Stühle aus dem Keller geholt.
I brought two chairs up from the basement.
Why these patterns are partly predictable
The single most useful predictor is gender, especially for feminine nouns:
- Feminine nouns take -(e)n roughly 90% of the time (die Frau → die Frauen, die Zeitung → die Zeitungen, die Blume → die Blumen). Feminine nouns essentially never take a zero plural and never take -er.
- Masculine and neuter nouns spread across -e, -er, zero, and -s, with masculines favouring -e and neuters favouring -er or -e.
- Loanwords, abbreviations and names — across all genders — lean toward -s (das Auto → die Autos, die SMS → die SMS, die Müllers).
The second predictor is the ending. Masculine and neuter nouns that already end in -er, -el, or -en usually take a zero plural — they have no room for another syllable, so often only the article (and sometimes an umlaut) marks the plural.
Alle Fenster im Haus sind offen.
All the windows in the house are open.
Meine Schwester hat drei Kinder.
My sister has three children.
The umlaut: German's hidden plural marker
In many -e, -er and zero plurals, the stem vowel also shifts: a → ä, o → ö, u → ü, au → äu. This is the umlaut, and it is not decoration — it is part of the plural and omitting it is an error, just as bad as forgetting the -s in English "books."
Crucially, only the back vowels a, o, u (and the diphthong au) can take an umlaut. A noun whose stem vowel is e or i can never umlaut, because there is nothing to shift. That gives you a quick filter: der Tisch has an i, so its plural can only be die Tische — there is no umlauted form to worry about. Contrast der Stuhl, whose u can shift, giving die Stühle.
Im Herbst fallen die Äpfel von den Bäumen.
In autumn the apples fall from the trees.
Die Mäuse sind nachts in der Küche.
The mice are in the kitchen at night.
Learn every noun as a triple
The deepest lesson of this page is a habit, not a rule. Because neither gender nor plural is fully predictable, you should store every new noun as three pieces of information at once: the gender (the article), the singular, and the plural.
Not "Buch," but das Buch, die Bücher. Not "Frau," but die Frau, die Frauen. Not "Apfel," but der Apfel, die Äpfel. Relearning the plural of a noun you already "know" is painful and slow; learning it the first time costs nothing extra.
Ich kaufe ein Buch. Sie kauft zwei Bücher.
I'm buying a book. She's buying two books.
Da steht ein Stuhl, dort stehen vier Stühle.
There's one chair here, and four chairs over there.
Common Mistakes
The errors below come almost entirely from English speakers importing the "just add -s" instinct, or from forgetting that the umlaut is mandatory.
❌ Ich habe drei Buchs gekauft.
Incorrect — English-style -s on a native German noun.
✅ Ich habe drei Bücher gekauft.
I bought three books. (das Buch → die Bücher: -er plural with umlaut)
❌ Im Garten stehen viele Tischs.
Incorrect — -s does not apply to native masculine nouns.
✅ Im Garten stehen viele Tische.
There are many tables in the garden. (der Tisch → die Tische)
❌ Wir haben zwei Stuhle.
Incorrect — the mandatory umlaut is missing.
✅ Wir haben zwei Stühle.
We have two chairs. (der Stuhl → die Stühle: u → ü)
❌ der Bücher liegt auf dem Tisch.
Incorrect — the plural article is never der; it is die.
✅ Die Bücher liegen auf dem Tisch.
The books are lying on the table.
❌ Die Tage werden länger und die Mäuse werden mehr.
Watch out — die Mäuse already has the umlaut, but learners often write die Mause.
✅ Die Mäuse sind wieder da.
The mice are back. (die Maus → die Mäuse: au → äu)
Key Takeaways
- German has five plural patterns: -e, -er, -(e)n, -s, and zero.
- The plural article is always die in the nominative, no matter the singular gender.
- Many plurals add an umlaut (a → ä, o → ö, u → ü, au → äu); only those four vowels can shift, and the umlaut is mandatory, never optional.
- Gender predicts the plural well: feminine → -(e)n about 90% of the time; loanwords → -s.
- Always learn a noun as a triple: article + singular + plural (das Buch, die Bücher).
From here, work through the patterns one at a time, starting with the -e plural, the most common pattern for masculine and neuter nouns.

- The -e Plural (with and without Umlaut)A2 — The -e plural is the workhorse pattern for masculine and many neuter nouns — masculines often add an umlaut, neuters usually don't, and feminines in this group nearly always do.
- The -er Plural (Always with Umlaut where Possible)A2 — The -er plural belongs to many neuter and a few masculine nouns, and it takes an obligatory umlaut whenever the stem vowel is a, o, u, or au — it never applies to feminine nouns.
- The -(e)n PluralA2 — The -(e)n plural dominates feminine nouns (about 90% take it) and the weak masculine n-nouns — it never takes an umlaut, and gender prediction by ending tells you in advance when it applies.
- The -s Plural (Loanwords and Abbreviations)A2 — The -s plural looks like the English default but is restricted to loanwords, vowel-final nouns, abbreviations and names — it never umlauts, takes no dative -n, and never uses an apostrophe.
- Zero-Ending and Umlaut-Only PluralsA2 — Why many German nouns look identical in the singular and plural — and how a sneaky umlaut on the vowel is sometimes the only clue that you mean more than one.
