学べること

Ready to level up your German? You've got the basics down, but in this chapter, we're diving deep into asking precise questions and pinpointing exactly what you mean, whether you're talking about people or objects. Imagine you're in a bustling Berlin cafe, wanting to order *that specific* coffee your friend just had, or you're browsing a shop, trying to ask for *which* shirt you're interested in; the skills you'll gain here are your new superpowers! We'll kick things off with Was – your straightforward what for things and actions, always easy. Then, we tackle the who family in German:

wer, wen, wem, wessen.
You'll learn to perfectly match who or whom to the grammatical role of the person you're asking about. This is super important for understanding who's doing what to whom, making your conversations much clearer! Next up, we unlock how to ask which one using welcher, welche, welches. These act like precise selectors, helping you narrow down choices and clearly communicate your selection, whether it's which book? or which car?. Finally, we'll master dieser, diese, dieses, which acts like a laser pointer! You'll use it to specify this or that, perfectly mirroring the endings of definite articles to match the noun's gender and case. By the end of this chapter, you'll confidently ask detailed, unambiguous questions and precisely refer to anything or anyone around you. You'll feel much more at home navigating real-life German conversations!

チャプターガイド

Overview

Ready to elevate your A2 German grammar? You've mastered the basics, but now it's time to refine your communication by learning how to ask precise questions and identify specific things or people. This chapter is your guide to becoming more articulate and confident in real-world German interactions.
Imagine yourself in a bustling German market, wanting to ask for *that specific* type of bread, or trying to figure out *who* is responsible for an event. The skills you'll gain here are fundamental for moving beyond simple statements and truly engaging in dynamic conversations. We'll explore essential German question words and demonstratives that will act as your linguistic laser pointer, enabling you to pinpoint exactly what you mean.
Mastering these structures is crucial for understanding nuanced meaning and making yourself understood clearly, a key step in your German language learning journey.

How This Grammar Works

This chapter focuses on several key tools for asking questions and identifying specifics. First, we tackle Was (What), your go-to for inquiries about things or actions. It's straightforward and doesn't change: Was ist das? (What is that?), Was machst du? (What are you doing?).
Next, we dive into the who family, which is crucial for understanding cases. Wer asks who in the nominative case (the subject): Wer kommt heute? (Who is coming today?). For the accusative case (the direct object), you use Wen: Wen siehst du? (Whom/Who do you see?).
When asking about the indirect object (dative case), you use Wem: Wem gibst du das Buch? (To whom/Who are you giving the book?). Finally, for possession (genitive case), it's Wessen: Wessen Handy ist das? (Whose phone is that?).
Moving on, we explore how to ask which one using welcher, welche, welches. These words function like articles and must agree in gender and case with the noun they refer to. For example, Welches Buch möchtest du? (Which book would you like?) uses welches because *Buch* is neuter accusative.
For a feminine noun in nominative, it's Welche Farbe magst du? (Which color do you like?). For a masculine noun in dative, it could be Mit welchem Freund gehst du? (With which friend are you going?). Lastly, we'll master dieser, diese, dieses (this/that).
These demonstratives also agree in gender and case with the noun, much like definite articles. Dieser Kaffee ist lecker. (This coffee is delicious.) (Dieser for masculine nominative *Kaffee*). Ich mag diese Tasche. (I like this bag.) (Diese for feminine accusative *Tasche*).
Understanding these agreements is fundamental for precise communication in German grammar.

Common Mistakes

  1. 1Wrong: Wer siehst du?
Correct: Wen siehst du?
*Explanation:* Wer is nominative (who is doing the action), but here du is the subject doing the seeing, and the person being seen is the direct object (accusative). Therefore, you need wen (whom).
  1. 1Wrong:
    Ich möchte dieser Apfel.
Correct:
Ich möchte diesen Apfel.
*Explanation:* Apfel is masculine, and in this sentence, Apfel is the direct object of möchte (I would like), which requires the accusative case. The accusative form for masculine dieser is diesen.
  1. 1Wrong:
    Was ist der Mann dort?
    (meaning
    Who is the man there?
    )
Correct:
Wer ist der Mann dort?
*Explanation:* Was is used for things or actions. When asking about a person, you must use wer (who), which is the correct question word for people in the nominative case.

Quick FAQ

Q

When do I use 'wer' vs. 'wem' in German?

Use wer (nominative) when asking about the subject of a sentence (who is doing something). Use wem (dative) when asking about the indirect object (to whom or for whom something is done).

Q

How do 'welcher' and 'dieser' change their endings in German?

Both welcher and dieser (and their feminine/neuter forms) change their endings to match the gender, number, and case of the noun they refer to, just like definite articles (der, die, das).

Q

Can 'was' be used for people in German?

No, was is exclusively for things or actions. For people, you must use the appropriate form of who (wer, wen, wem, wessen), depending on the grammatical case.

Cultural Context

In German conversations, directness is often valued. Using precise question words like wer or was, and demonstratives like dieser, helps avoid ambiguity and is considered perfectly polite and clear. Unlike some languages where being too direct might be seen as impolite, in German, it's often preferred for clear communication.
There aren't significant regional differences in the usage of these core grammatical structures; they are universally understood and applied across German-speaking countries, making your learning broadly applicable.

ヒントとコツ (4)

🎯

「Etwas」のショートカット

ドイツ人が「何か食べたい?」と聞く時、「Möchtest du etwas essen?」と言う代わりに、もっとカジュアルに「Möchtest du was essen?」と「etwas」を短くして言うことがあります。あなたも使ってみて、ネイティブっぽく話してみましょう!

💡

「m」の魔法

誰かに何かを与える時に「彼に」(ihm)と答えるなら、「誰に?」(wem)を使うんだ。「ihm」も「wem」も語尾が「m」で終わるから、この「m」をヒントにするといいよ!
frontend.learn_grammar.from_rule: 「誰?」と尋ねる (wer, wen, wem, wessen)
🎯

「-n」のコツ

答えが「den Mann」や「einen Freund」のように「-n」で終わるなら、質問も「wen」と「-n」で終わるはずです:Wen triffst du?
frontend.learn_grammar.from_rule: 「誰を」と尋ねる (wen)
🎯

冠詞の鏡

もし迷ったら、「der, die, das」を思い出して。「den」を使う名詞なら、「welchen」を使います。語尾はだいたい一致しますよ! "Wenn du 'den' sagst, dann sagst du auch 'welchen'."

Review Summary

  • Was + Verb...?
  • Wer/Wen/Wem/Wessen + Verb...?
  • Welch- / Dies- + [Ending]

よくある間違い

In German, you cannot use 'Was' for people. Use 'Wer' (Who) instead, even if you are asking about their identity.

Wrong: Was ist das Mann?
正解: Wer ist der Mann?

'Buch' is neuter (das Buch). The ending of 'welcher' must match the gender and case of the noun.

Wrong: Welcher Buch liest du?
正解: Welches Buch liest du?

The person being loved is the direct object (Accusative). Therefore, you must use 'wen' instead of the subject form 'wer'.

Wrong: Wer liebst du?
正解: Wen liebst du?

よくある質問 (6)

いいえ、「was」は単数でも複数でも「was」のままです。例えば、「Was ist das?」(単数)も「Was sind das?」(複数)も両方正しく使えます。
はい、使えますよ!「Was bist du von Beruf?」(あなたの職業は何ですか?)や「Was arbeitest du?」(あなたは何の仕事をしていますか?)のように尋ねることができます。この場合、「was」は職業や活動を指し、人そのものを指すわけではありません。
そうだよ、「wer」は文法的にはいつも単数形なんだ。たとえ10人のグループを見ても、「Wer ist das?」(あれは誰?)と聞くよ。複数形「Wer sind das?」とは言わないんだ。
「wen」は直接目的語(2格)に、そして「wem」は間接目的語や3格をとる動詞の後に使うんだ。例えば、「Wen siehst du?」(誰を見る?)と「Wem hilfst du?」(誰を手伝う?)の違いだね。
「n」を覚えることです。「den」や「einen」と同じように、「wen」は人について尋ねる対格の形です。もし誰かが目的語なら、「n」を付け加えるのを思い出しましょう。
厳密には、動物には通常「was」を使います。しかし、親しい会話でペットを人のように扱うなら、「Wen fütterst du?」(誰に餌をあげているの?)のように「wen」を使っても、とても愛情深く聞こえますよ。
