How to say "which" in German
in German, „was“ can be used to mean “which” in certain situations, not just „welcher“.
But here's the key:
They’re used in different grammatical contexts.
✅ When to use „was“ as “which”:
You use „was“ as a relative pronoun to mean "which" or "what", but only after:
- Indefinite nouns like:
- alles (everything)
- nichts (nothing)
- etwas (something)
- viel (much), wenig (little)
- das (in some general uses)
- Whole clauses, when referring to the entire idea that came before.
🔍 Examples:
1. After indefinite words:
- Alles, was er sagt, ist wichtig.
- → Everything (that) he says is important.
- Etwas, was mir gefallen hat, war die Musik.
- → Something I liked was the music.
2. Referring to a whole previous idea:
- Er kam zu spät, was allerdings sehr nützlich war.
- → He arrived late, which, however, was very useful.
- (→ "was" refers to the whole action of coming late)
❌ When not to use "was":
If you’re referring to a specific noun like:
- der Mann, die Frau, das Buch → use welcher, die, or das (depending on gender/case).
Example:
- Das Buch, das ich gelesen habe, war spannend. ✅
- → The book that I read was exciting.
Not: ✖️ Das Buch, was ich gelesen habe...
🧠 Summary:
Use | Relative Pronoun |
After das, alles, nichts, etwas, etc. | ✅ was |
Referring to an entire previous idea/sentence | ✅ was |
Referring to a specific noun with gender | ✅ der/die/das or welcher (depends on context) |
✅ When to use „welcher“
Use „welcher“ when:
- You're referring to a specific noun (not indefinite like „alles“ or „etwas“).
- You want a more formal, literary, or clear way to say “which” in a relative clause.
- You need to avoid confusion when using der/die/das as relative pronouns would be ambiguous.
🧠 Examples:
🟦 Nominative (subject of the clause)
- Der Mann, welcher dort steht, ist mein Lehrer.
- → The man who is standing there is my teacher.
🟥 Accusative (object of the clause)
- Die Frau, welche ich gestern gesehen habe, ist meine Nachbarin.
- → The woman whom I saw yesterday is my neighbor.
🟨 Dative
- Das Kind, welchem ich das Buch gegeben habe, war sehr dankbar.
- → The child to whom I gave the book was very grateful.
🟩 Plural
- Die Leute, welche dort wohnen, sind sehr freundlich.
- → The people who live there are very friendly.
👥 Comparison with „der/die/das“
These mean the same but are more commonly used in spoken German:
- Der Mann, der dort steht = The man who is standing there
- Die Frau, die ich gesehen habe = The woman I saw
👉 Use „welcher“ mainly in written, formal, or clarity-demanding situations.
🧩 Tip:
You’ll usually find „welcher“ more often in legal, academic, or literary German. In everyday speech, der/die/das as relative pronouns are more natural.
