Forming yes/no questions and W-questions (verb-first order, question words)

Forming yes/no questions and W-questions in German (verb-first order and question words)

This guide explains how to make direct questions in German: yes/no questions and W-questions (questions that begin with a question word). German direct questions normally put the conjugated verb first (verb-first word order). You will see when and why that happens, how to form questions in different tenses and with different verb types, how to use German question words (wer, was, wann, wo, warum, wie, welcher, etc.), and common learner mistakes to avoid. Examples are in German with clear English translations.

What does "verb-first" mean?

In German main-clause questions, the conjugated verb comes in first position. Compare a statement and a question:

- Statement: Du gehst nach Hause. — You are going home.
- Yes/no question (verb-first): Gehst du nach Hause? — Are you going home?
- W-question (question word first): Wohin gehst du? — Where are you going?

In English we often use an auxiliary (do/does/did/have) to form questions; German does not use "do". German simply moves the conjugated verb to the front.

When do I use yes/no questions and W-questions?

- Yes/no questions ask for confirmation or denial: "Is it true that...?" Example: Kommst du morgen? — Are you coming tomorrow?
- W-questions ask for specific information (who, what, where, when, why, how, which). Example: Wann kommst du? — When are you coming?

Both types are direct questions and follow verb-first order (except in subordinate clauses or indirect questions; see below).

How do I form yes/no questions (verb-first)?

Formula for a direct yes/no question (main clause):

- Conjugated verb + subject + rest of the sentence.

Examples in different tenses and verb types:

Present (Präsens)
- Spielst du heute Fußball? — Are you playing football today?
- Bist du müde? — Are you tired?

Perfect (Perfekt) — auxiliary first
- Hast du das Buch gelesen? — Have you read the book?
- Bist du schon angekommen? — Have you already arrived?

Simple past (Präteritum)
- Warst du gestern zu Hause? — Were you at home yesterday?
- Gingst du allein? — Did you go alone?

Future (Futur I)
- Wirst du morgen kommen? — Will you come tomorrow?

Modal verbs (can, must, want, etc.)
- Kannst du mir helfen? — Can you help me?
- Musst du heute arbeiten? — Do you have to work today?

Separable-prefix verbs
- Stehst du morgen früh auf? — Are you getting up early tomorrow? (conjugated part "stehst" first, prefix "auf" goes to the end)
- Fängt der Kurs um neun an? — Does the course start at nine?

Reflexive verbs
- Hast du dich verletzt? — Did you hurt yourself?

Formal (Sie) and polite forms
- Haben Sie Zeit? — Do you have time? (formal)
- Würden Sie mir bitte helfen? — Would you please help me? (very polite: conditional/modal)

Short answers
- Kommst du? — Ja. / Nein. / Doch. — Are you coming? — Yes. / No. / (Doch = contradicting a negative)

Note: In very casual spoken German some speakers use declarative word order with rising intonation ("Du kommst morgen?") to indicate a question. This is common in conversation but is informal. The standard written and formal spoken form is verb-first.

How do I form W-questions (question words)?

Formula for direct W-questions (main clause):

- Question word + conjugated verb + subject + rest.

Common question words and examples (with notes about case and differences):

Wer / Wen / Wem (who — nominative / accusative / dative)
- Wer hat das gesagt? — Who said that? (wer = subject)
- Wen siehst du? — Whom do you see? (wen = direct object)
- Wem gibst du das Buch? — To whom are you giving the book? (wem = indirect object)

Was (what)
- Was machst du? — What are you doing?
- Was bedeutet dieses Wort? — What does this word mean?

Welcher, welche, welches (which + noun) — declined to match gender/number/case
- Welches Buch liest du? — Which book are you reading? (neuter: welches)
- Welche Musik magst du? — Which music do you like? (feminine: welche)
- Welcher Tag passt dir? — Which day suits you? (masculine: welcher)

Wann (when)
- Wann beginnt der Film? — When does the movie start?

Wo / Wohin / Woher (where / to where / from where)
- Wo wohnst du? — Where do you live?
- Wohin gehst du? — Where are you going (to)?
- Woher kommst du? — Where do you come from?

Warum / Wieso / Weshalb (why — synonyms)
- Warum lernst du Deutsch? — Why are you learning German?
- Wieso bist du spät? — Why are you late?

Wie (how) and Wie viel / Wie viele (how much / how many)
- Wie geht es dir? — How are you?
- Wie alt bist du? — How old are you?
- Wie viel kostet das? — How much does that cost? (countable/uncountable difference)
- Wie viele Bücher hast du? — How many books do you have?

Preposition + question words (wo- + preposition, or preposition + wem/wen)
- Mit wem sprichst du? — With whom are you speaking?
- Womit schreibst du? — What are you writing with? / With what are you writing?
- Worauf wartest du? — What are you waiting for? ("wo-" + "auf")
- Worüber redet ihr? — What are you talking about? ("wo-" + "über")

Note on choosing forms: For people, use "wer/wen/wem" (watch the case). For things, use "was", "wo-..." forms or preposition + "was"/"wor-" combinations.

Word order with auxiliaries, modals, separable verbs, and special cases

- In Perfekt and other compound tenses, the auxiliary (haben/sein) is the conjugated verb. Put it first in a question: Hast du geschlafen? — Have you slept?
- With modal verbs in the present, the modal is conjugated and goes first: Musst du gehen? — Do you have to go?
- Separable verbs split in main clauses: the conjugated verb appears first; the separable prefix goes to the end: Rufst du mich an? — Are you calling me? (anrufen)
- With modal verbs in the perfect (double infinitive construction): Hast du das machen müssen? — Did you have to do that? (auxiliary has first position)

Indirect questions (using "ob" and subordinate clauses)

Direct questions (what we've covered so far) are verb-first. Indirect questions — when you embed a question in a larger sentence — use subordinate-clause word order: the finite verb goes to the end.

Examples:
- Direct yes/no: Kommst du morgen? — Are you coming tomorrow?
- Indirect: Ich weiß nicht, ob du morgen kommst. — I don’t know whether you are coming tomorrow. ("ob" + subject + verb at end)

- Direct W-question: Wo ist der Bahnhof? — Where is the station?
- Indirect: Können Sie mir sagen, wo der Bahnhof ist? — Can you tell me where the station is? (question word + subject + verb at end)

Remember: Use "ob" to introduce indirect yes/no questions. For indirect W-questions, start with the W-word and then subject + verb-final.

Answers: short answers and contrastive "doch"

- Short confirmations: Ja. / Nein.
- To contradict a negative question or statement, use "doch":
- Hast du kein Brot? — Doch, ich habe Brot. — Do you have no bread? — Yes I do (contradicting the negative).
- Short answers can also repeat the verb or subject: Kommst du? — Ja, ich komme. — Are you coming? — Yes, I am coming.

Common mistakes to avoid

1) Forgetting verb-first order in direct questions (writing statement order instead):
- Incorrect: Du kommst morgen? (colloquial) — Correct (standard): Kommst du morgen?

2) Using the wrong question form for people vs things (wer vs was):
- Incorrect: Was hat das gesagt? (for a person) — Correct: Wer hat das gesagt?

3) Confusing wer/wen/wem (case errors):
- Incorrect: Wer siehst du? — Correct: Wen siehst du? (wen = accusative)

4) Mixing up wo / wohin / woher:
- Incorrect: Wo gehst du? (if you mean "to where") — Correct: Wohin gehst du?

5) Placing separable prefixes in the wrong place:
- Incorrect: Wann du stehst auf? — Correct: Wann stehst du auf?

6) Using "ob" with W-questions:
- Incorrect: Ich weiß nicht, ob wann er kommt. — Correct: Ich weiß nicht, wann er kommt.

Quick reference: formulas and examples

- Yes/no question: Verb + Subject + (Objects/Adverbials)
- Hast du Zeit? — Do you have time?
- Kannst du das sehen? — Can you see that?

- W-question: Question word + Verb + Subject + (Rest)
- Wo arbeitest du? — Where do you work?
- Warum lernst du? — Why are you learning?

- Indirect yes/no question: ... ob + Subject + Verb(final)
- Er fragt, ob du kommst. — He asks whether you are coming.

- Indirect W-question: ... W-word + Subject + Verb(final)
- Sag mir, wann der Zug abfährt. — Tell me when the train leaves.

- Separable verb question: Conjugated verb + Subject + ... + prefix at end
- Rufst du mich später an? — Are you calling me later?

Glossary (simple definitions)

Conjugated verb: the verb form that matches the subject (e.g., "gehst" for "du").
Auxiliary verb: a helper verb used to build compound tenses (haben, sein, werden).
Separable prefix: part of a verb that separates in main clauses and appears at the end (e.g., "an" in "anrufen").
Indirect question / subordinate clause: a question embedded in a larger sentence; the finite verb goes to the end.
Ob: German word for "whether"; used to introduce indirect yes/no questions.
Nominative / Accusative / Dative: the German cases; important because "wer/wen/wem" change depending on case.

Conclusion and quick tips

- For direct questions in German, move the conjugated verb to the first position (verb-first).
- Use a question word (wer, was, wo, wann, warum, wie, welcher) when you need specific information; otherwise form a yes/no question with the verb first.
- In indirect questions and subordinate clauses, use subject + verb-final word order and use "ob" for yes/no questions.
- Pay attention to case (wer/wen/wem) and to prepositions (mit wem vs womit; wohin vs woher).
- In spoken informal German you may hear sentence-order questions with rising intonation; in writing and formal speech use verb-first.

Practice by turning statements into questions and by making both yes/no and W-questions for the same content. Over time the verb-first pattern will become natural.
