学べること

You've nailed the basics, awesome! Now, let's dive into an exciting new level that'll make your German sound much more professional and authentic. In this chapter, you're going to master the power of plurals and the magic of German compound words. First, we'll learn how to form plurals for nouns in German. It might seem tricky at first, but you'll see how logical it all is! You'll discover when to simply add an «-e» (like Hunde and Tage), when «-n» or -en comes into play (especially for feminine nouns, no tricky Umlauts needed!), when -er appears with an Umlaut (like Kinder), and even words that don't change at all in the plural (like Lehrer). Plus, you'll see how easy it is to make foreign words plural with a simple «-s» (like Autos). But the most thrilling part? German compound words! You know, those long, fascinating words that stick several smaller words together to create a completely new meaning? We'll teach you the golden rule: in these compounds, the last word is always the boss! It dictates the gender and how the entire word forms its plural. This is a super useful trick you'll use constantly. Where will these skills really come in handy? Imagine you're shopping in Germany and want to say three flowers or four books. You'll need to know your plurals! Or when you want to talk about more complex things, like a car key (Autoschlüssel), compound words are essential. By the end of this chapter, you'll confidently be able to make tons of words plural and use German compound words like a native speaker. Your conversations will flow more smoothly and naturally, and you won't have any trouble forming longer, more intricate sentences. Ready for this new power in German? Let's go!

How This Grammar Works

Let's dive into the mechanics of making your German more flexible and descriptive. First, the world of German plurals. Unlike English, German has several ways to form plurals, but don't worry – we'll break them down.
One common pattern is the German Plural Trick: Just Add -e. You'll see this with words like der Hund (the dog) becoming die Hunde (the dogs), or der Tag (the day) becoming die Tage (the days). Another frequent method is German Plurals: Adding -n or -en, especially common for many feminine nouns.
For instance, die Blume (the flower) becomes die Blumen (the flowers), and die Frau (the woman) turns into die Frauen (the women). Notice there are no Umlauts here! Then there's German Plurals: Adding -er, often accompanied by an Umlaut for some masculine and neuter nouns: das Kind (the child) becomes die Kinder (the children), and das Haus (the house) transforms into die Häuser (the houses).
A simpler category is The 'No Change' Plural, often for masculine nouns ending in -er, -el, or -en. So, der Lehrer (the teacher) remains die Lehrer (the teachers) in the plural, and das Mädchen (the girl) stays die Mädchen (the girls). Finally, for many foreign words, there's German Plurals: The Easy '-s' Ending: das Auto (the car) becomes die Autos (the cars), and das Team (the team) is simply die Teams (the teams).
Now for the exciting part: German Compound Nouns: The Last Word is Boss (Komposita). German loves to combine words to create new, highly specific meanings. The golden rule here is that the *last* word in the compound dictates the gender and how the entire compound forms its plural.
For example, in der Autoschlüssel (the car key), Auto is neuter (das Auto), but Schlüssel is masculine (der Schlüssel). Because Schlüssel is the last word, Autoschlüssel is masculine (der Autoschlüssel), and its plural is die Autoschlüssel (the car keys), just like die Schlüssel (the keys). This rule simplifies understanding these complex words immensely!

Common Mistakes

  1. 1Wrong:
    Ich sehe viele Hausen.
    (I see many house-s.)
Correct:
Ich sehe viele Häuser.
(I see many houses.)
*Explanation:* The noun Haus takes an -er ending with an Umlaut in the plural, not -en. Always learn the plural form with the noun.
  1. 1Wrong:
    Das ist ein Schreibtischlampe.
    (That is a desk lamp.)
Correct:
Das ist eine Schreibtischlampe.
(That is a desk lamp.)
*Explanation:* The last word, Lampe (lamp), is feminine (die Lampe), so the entire compound Schreibtischlampe (desk lamp) is feminine, requiring the feminine indefinite article eine.
  1. 1Wrong:
    Ich habe drei Buchen gelesen.
    (I have read three book-s.)
Correct:
Ich habe drei Bücher gelesen.
(I have read three books.)
*Explanation:* The plural of das Buch (the book) is die Bücher, using the -er ending with an Umlaut, not -en.

Quick FAQ

Q

Why are German plurals so inconsistent? Is there a secret rule for all of them?

Unfortunately, there's no single secret rule that applies to all German plurals. The variations stem from historical linguistic developments. The best approach for A2 German is to learn each noun with its plural form (e.g., das Buch, die Bücher), but recognizing the common patterns we discussed will help you make educated guesses.

Q

How do I know the gender of a German compound noun?

The gender of a German compound noun is always determined by the last noun in the compound. For example, die Haustür (the house door) is feminine because die Tür (the door) is feminine.

Q

Do all nouns ending in -er, -el, or -en have no plural change?

While many do, especially masculine nouns, it's not a universal rule. For instance, der Teller (the plate) stays die Teller, but der Fehler (the mistake) is die Fehler. Always verify if unsure, but it's a very common pattern to look for.

Cultural Context

German compound words are more than just grammar rules; they're a reflection of German culture's precision and efficiency. Native German speakers naturally combine words to create highly specific terms, like Donaudampfschifffahrtsgesellschaftskapitän (Danube steamship company captain), which would require multiple words in English. This allows for nuanced expression and often makes communication more direct, as a single word conveys a complex idea.
While plural forms might seem challenging, they are used constantly in everyday conversation, ensuring clarity when referring to multiple items or people. Mastering these aspects will not only improve your German grammar A2 but also your ability to think and express yourself like a native.

ヒントとコツ (4)

⚠️

ウムラウトの落とし穴

点々(ウムラウト)を忘れないでね!男性名詞で「a, o, u」を含む単語は、「-e」をつける時に「ä, ö, ü」に変わることが多いんだ。例えば、「木」は Baum から Bäume になるよ。
frontend.learn_grammar.from_rule: ドイツ語の名詞の複数形:-e をつける (Hunde, Tage, Brote)
💡

女性名詞のルール

単語が「die」で始まる女性名詞の場合、複数形は「-n」か「-en」をつけるのが一番確実な方法です。ほとんどの場合、これでうまくいきますよ!例えば、女性の友達について話す時、「Die Frauen sind hier.」と言えます。
frontend.learn_grammar.from_rule: ドイツ語の複数形:-n または -en の追加
🎯

ウムラウトの磁石!

「-er」で複数形になる名詞で、「a」「o」「u」「au」の母音があれば、ほぼ確実にウムラウトがつきます。これはとっても大事なルールですよ!例えば、「das Buch」が「die Bücher」になるように。die Bücher
frontend.learn_grammar.from_rule: ドイツ語の複数形:-er をつける (子供たち、家など)
🎯

動詞に注目!

先生が一人か複数か迷った時、動詞に注目してください。動詞がヒントをくれます。「Der Lehrer *ist*」(単数) と「Die Lehrer *sind*」(複数) のように、動詞が変わりますよ。

Review Summary

  • der/das Noun + -e
  • die Noun + -(e)n
  • Word A + Word B = Gender of B

よくある間違い

Foreign words ending in vowels almost always take an -s plural. Don't leave them in the singular form.

Wrong: Die zwei Auto sind blau.
正解: Die zwei Autos sind blau.

The gender comes from 'die Tür', not 'das Haus'. Always look at the very last part of the compound word.

Wrong: Das Haustür ist offen.
正解: Die Haustür ist offen.

Many -er plurals require an Umlaut (a -> ä, o -> ö, u -> ü). Forgetting the dots is a common spelling error.

Wrong: Ich habe zwei Bucher.
正解: Ich habe zwei Bücher.

よくある質問 (6)

ほとんどの男性名詞で「a, o, u」を含むものは、「-e」をつけて複数形にする時にウムラウトがつきます。中性名詞はほとんどつきません。例えば、「Baum」(木)は Bäume になるけど、「Brot」(パン)は Brote のままです。
ごく稀にあります。いくつかの一音節の単語はそうなることがあり、その場合は必ずウムラウトがつきます。例えば、「Hand」(手)は Hände に、「Nacht」(夜)は Nächte になります。
発音のしやすさで決まります!単語の終わりが「-e」のような柔らかい音なら、シンプルに「-n」をつけます。例えば、「{die|f} Tasche」は「die Taschen」になります。でも、硬い子音で終わる場合は、「-en」をつけるとスムーズに聞こえますよ。「{die|f} Übung」は「die Übungen」です。
はい、ありますが、「N変化名詞」と呼ばれる特定のグループだけです。例えば、「{der|m} Junge」や「{der|m} Kollege」などですね。ほとんどの男性名詞は「-e」の語尾を好みます。
ウムラウトがつくのは「a」「o」「u」「au」の母音だけです。「Kind」や「Lied」のように「i」や「e」の母音には、ドイツ語の複数形ではウムラウトはつきません。「das Kind」は「die Kinder」になります。
よく使われるものは約100語あります。ほとんどが中性名詞で短い単語です。「Kind」「Haus」「Buch」「Mann」を覚えるだけで、日常会話の80%はカバーできますよ。「das Haus」が「die Häuser」になるのはよく使いますね。
