See the A1 courseModal verbs are a small but powerful group of verbs in German that modify the meaning of the main verb in a sentence. They express concepts like ability, permission, obligation, desire, and preference. If you are learning German grammar, mastering modal verbs is one of the most important steps you can take at the A2 level.
There are six core modal verbs in German: können, müssen, dürfen, sollen, wollen, and mögen. Many textbooks and learners count möchten (the subjunctive form of mögen, meaning "would like to") as a seventh modal verb because it behaves like one in everyday speech. In this guide, we cover all seven so you are fully prepared.
Modal verbs follow a specific sentence structure: the modal verb takes the conjugated (second) position in the sentence, and the main verb goes to the end in its infinitive form. For example: Ich kann Deutsch sprechen (I can speak German).
Understanding modal verbs will unlock your ability to express what you can do, must do, want to do, and are allowed to do in German. They appear in nearly every conversation and are essential for passing any German proficiency exam.
Here is a quick overview of all seven German modal verbs, their core meanings, and English equivalents:
| Modal Verb | Meaning | English Equivalent |
|---|---|---|
| können | ability, possibility | can, to be able to |
| müssen | necessity, obligation | must, to have to |
| dürfen | permission | may, to be allowed to |
| sollen | recommendation, duty | should, to be supposed to |
| wollen | strong desire, intention | to want to |
| mögen | preference, liking | to like |
| möchten | polite wish | would like to |
Now let us look at each modal verb in detail with its conjugation table and example sentences. If you need a refresher on how German verb conjugation works in general, check out our dedicated guide first.
Können expresses ability or possibility. It is one of the most frequently used modal verbs.
| Pronoun | Conjugation |
|---|---|
| ich | kann |
| du | kannst |
| er/sie/es | kann |
| wir | können |
| ihr | könnt |
| sie/Sie | können |
Common mistake: Do not confuse können with kennen (to know/be acquainted with). They sound similar but have completely different meanings.
Müssen expresses necessity or obligation. It is the verb you need when something is required.
| Pronoun | Conjugation |
|---|---|
| ich | muss |
| du | musst |
| er/sie/es | muss |
| wir | müssen |
| ihr | müsst |
| sie/Sie | müssen |
Common mistake: In English, "must not" means "forbidden." In German, nicht müssen means "do not have to" (no obligation). To say "must not" or "forbidden," use nicht dürfen instead.
Dürfen expresses permission or prohibition (when negated).
| Pronoun | Conjugation |
|---|---|
| ich | darf |
| du | darfst |
| er/sie/es | darf |
| wir | dürfen |
| ihr | dürft |
| sie/Sie | dürfen |
Common mistake: Learners often use können when they mean dürfen. Remember: können is about ability, dürfen is about permission.
Sollen expresses a recommendation, duty, or something someone else expects of you.
| Pronoun | Conjugation |
|---|---|
| ich | soll |
| du | sollst |
| er/sie/es | soll |
| wir | sollen |
| ihr | sollt |
| sie/Sie | sollen |
Common mistake: Sollen often implies that someone else has told you to do something, unlike müssen, which is a stronger personal obligation. Do not use them interchangeably.
Wollen expresses a strong desire or firm intention.
| Pronoun | Conjugation |
|---|---|
| ich | will |
| du | willst |
| er/sie/es | will |
| wir | wollen |
| ihr | wollt |
| sie/Sie | wollen |
Common mistake: English speakers often confuse will with the English future tense helper "will." German will means "want to," not "will" as in the future. The German future tense uses werden instead.
Mögen expresses preference or liking. It is often used without a second verb.
| Pronoun | Conjugation |
|---|---|
| ich | mag |
| du | magst |
| er/sie/es | mag |
| wir | mögen |
| ihr | mögt |
| sie/Sie | mögen |
Common mistake: Unlike other modal verbs, mögen is frequently used on its own with a noun rather than with an infinitive verb. Saying Ich mag schwimmen is grammatically possible but less common than Ich schwimme gern.
Möchten is technically the subjunctive (Konjunktiv II) form of mögen, but it functions as its own modal verb in everyday German. It expresses a polite wish or request.
| Pronoun | Conjugation |
|---|---|
| ich | möchte |
| du | möchtest |
| er/sie/es | möchte |
| wir | möchten |
| ihr | möchtet |
| sie/Sie | möchten |
Common mistake: Beginners sometimes use wollen when möchten would be more appropriate. Wollen is direct and can sound demanding, while möchten is the polite choice, especially in restaurants, shops, and formal situations.
This is one of the most common questions German learners ask, and getting it right is crucial. Both können and dürfen can be translated as "can" in English, but they have distinct meanings in German.
Können refers to ability -- what you are physically or mentally capable of doing:
Dürfen refers to permission -- what you are allowed or not allowed to do:
Here is a side-by-side comparison that makes the difference clear:
| Situation | Können | Dürfen |
|---|---|---|
| Swimming ability | Ich kann schwimmen. (I can swim.) | -- |
| Pool rules | -- | Man darf hier nicht schwimmen. (You are not allowed to swim here.) |
| Driving skill | Sie kann Auto fahren. (She can drive.) | -- |
| Driving age | -- | Mit 16 darf man in Deutschland nicht Auto fahren. (At 16, you are not allowed to drive in Germany.) |
A helpful rule of thumb: if the sentence is about a skill or capability, use können. If it is about rules, laws, or someone granting permission, use dürfen.
German modal verbs follow a distinctive conjugation pattern that sets them apart from regular verbs. Here are the key rules to remember:
1. Stem vowel change in singular forms: All modal verbs (except sollen) change their stem vowel in the ich, du, and er/sie/es forms. For example, können becomes kann, kannst, kann in the singular.
2. No ending for ich and er/sie/es: Unlike regular verbs, modal verbs have no ending in the first and third person singular. You say ich kann (not ich kanne) and er kann (not er kannt).
3. Plural forms keep the infinitive stem: The wir, ihr, and sie/Sie forms use the original infinitive stem vowel. So while ich muss, the plural is wir müssen.
4. The main verb goes to the end: In a sentence with a modal verb, the main verb appears at the end in its infinitive form: Ich muss heute viel arbeiten. (I have to work a lot today.)
For the present tense specifically, memorizing the singular forms is the main challenge since they are irregular. The plural forms are predictable.
When forming the past tense (Perfekt), modal verbs behave differently again. Instead of using a past participle, they use a double infinitive construction: Ich habe schwimmen können. (I was able to swim.) However, in spoken German, the Präteritum (simple past) is more common for modal verbs: Ich konnte schwimmen.
Modal verbs appear so frequently in German that the best way to learn them is through active practice. Here are some effective strategies:
1. Practice with games: Play Memory Match to pair modal verbs with their meanings.
2. Take a quiz: Test your knowledge with our verb conjugation quizzes to see how well you know your modal verb forms. For broader grammar practice, our grammar quizzes include modal verb exercises in context.
3. Build sentences daily: Pick one modal verb each day and write five sentences using it. This builds muscle memory faster than just reading conjugation tables.
4. Listen for modal verbs: When watching German media or listening to podcasts, pay attention to how native speakers use modal verbs. You will notice they appear in almost every other sentence.
5. Learn common phrases: Many everyday German expressions use modal verbs. Memorize phrases like Kann ich Ihnen helfen? (Can I help you?) or Das darf nicht wahr sein! (That cannot be true!) to sound more natural.
The seven German modal verbs -- können, müssen, dürfen, sollen, wollen, mögen, and möchten -- are among the most essential verbs in the language. They follow unique conjugation patterns with stem vowel changes in singular forms and send the main verb to the end of the sentence in its infinitive form.
The most important distinctions to remember are: können (ability) vs. dürfen (permission), müssen (obligation) vs. sollen (recommendation), and wollen (strong want) vs. möchten (polite request).
