But some grammar concepts will boost your speaking skills more than others.
That's why, in this post, I'm going over German modal verbs which will make a massive difference in your ability to chat to Germans in day to day life. Modal verbs in German are words like want, may, like, must, can, and should that allow you to express an obligation or possibility.
For example, when ordering food, talking about your preferences, or asking permission for something, you need a modal verb. So that covers a ton of everyday speaking situations.
These irregular verbs are essential when speaking German, and learning them will instantly enhance your conversational skills.
I'll explain how to use each of the six most common modal verbs in the present, past, and future tenses. I'm also providing plenty of example sentences to help you use these verbs like a native speaker.

What Are German Modal Verbs?
The modal verbs in German are:
- können (can)
- dürfen (may)
- mögen (like)
- müssen (must)
- sollen (should)
- wollen (want).
These words allow you to express what you're supposed to do, what you're able to do, and other similar moods. Aside from specific idiomatic expressions, each modal verb has a distinct meaning.
Most of the time, you'll find modal verbs combined with other verbs in a sentence.
Why You Should Learn German Modal Verbs
Modal verbs are unique words that tell us more about the main verbs in a sentence.
You use them every day to ask for permission and express your ability or willingness to do something.
Imagine asking the following questions without a modal verb.
- Can I take you to the movies?
- Do my friends want a drink?
- How long should I wait for the bus?
It's essential to recognize modal verbs and know how to use them. Otherwise, you won't know if someone is asking or demanding something of you.
Knowing these verbs will significantly improve your ability to understand and be understood in German accurately.
#1 Können – Can
Let's look at one of the most frequently-used modal verbs, können. This verb lets you describe what you can or are able to do.
In the examples below, note how the modal verb is conjugated, but the main verb is in its original, or infinitive form.
- Example: Ich kann Deutsch sprechen. (I can speak German.)
- Example: Du kannst gut kochen. (You can cook well.)
- Example: Wir können morgen ins Kino gehen. (We can go to the movies tomorrow.)
Below, you'll see how to conjugate the verb können for each personal pronoun in the present and past tenses.
You may have noticed that the first vowel changes from “ö” to “a” in the present tense.
Rule #1 – Every modal verb, except for sollen, changes its first vowel for the pronouns I, you, he, she, and it.
In the simple past tense, you can see how können loses its umlaut.
Rule #2 – All of the modal verbs drop their umlauts in the past tense.
- Example: Ich konnte Deutsch sprechen. (I was able to speak German.)
- Example: Du konntest gut kochen. (You were able to cook well.)
- Example: Wir konnten ins Kino gehen. (We were able to go to the movies.)
The modal verb comes second in this construction and the main verb takes the last position in the sentence.
Create the past participle with a form of haben and the infinitive form of können. The main verb will also be in the infinitive form to construct what we call the double infinitive. Place both verbs at the end of the sentence together. The modal verb comes last.
- Example: Ich habe Deutsch sprechen können. (I was able to speak German.)
- Example: Du hast gut kochen können. (You were able to cook well.)
- Example: Wir haben gestern ins Kino gehen können. (We were able to go to the movies.)
When the sentence has no main verb, use a form of haben with gekonnt to create the past participle.
- Example: Ich habe Deutsch gekonnt. (I was able to “speak” German.)
- Example: Das hast du gut gekonnt. (You were able to do that well.)
- Example: Wir haben gestern ins Kino gekonnt. (We could have “gone” to the movies.)
It's common in spoken German to leave out the main verb and imply its meaning.
#2 Müssen – Must
When you want to talk about things you have to do, or must do, use müssen in German.
Again, notice how the first vowel changes, this time from an “ü” to a “u.” Remember this change is only for the pronouns I, you, he, she, and it.
- Example: Ich muss arbeiten. (I have to work.)
- Example: Du musst warten. (You must wait.)
- Example: Wir müssen morgen früh aufstehen. (We must get up early tomorrow.)
Let's see how müssen is conjugated.
Notice how the endings in the simple past form are the same for müssen as they were for können. Recognizing these patterns make it easier to learn how modal verbs behave.
Next, let's look at some examples in the simple past tense.
- Example: Ich musste arbeiten. (I had to work.)
- Example: Du musstest warten. (You had to wait.)
- Example: Wir mussten früh aufstehen. (We had to get up early.)
Remember that the simple past is most often used in written German. The past participle is more common in spoken German. The same rule for können applies here. Use a conjugated form of haben, then the main verb, and finally the infinitive müssen at the end.
- Example: Ich habe arbeiten müssen. (I had to work.)
- Example: Du hast warten müssen. (You had to wait.)
- Example: Wir haben früh aufstehen müssen. (We had to get up early.)
In some cases, you'll use the past participle form that includes haben and gemusst.
- Example: Ich habe gemusst. (I had to.)
- Example: Er hat gemusst. (He had to.)
- Example: Ihr habt gemusst. (You, plural, had to.)
Only use this form when there is no main verb.
#3 Mögen – Like
Mögen is a modal verb that you use to talk about who or what you like. This modal verb is often used on its own or combined with other verbs.
Notice how the “ö” in mögen changes to an “a” in the present tense.
- Example: Ich mag dich. (I like you.)
- Example: Ihr mögt Pizza. (You, plural, like pizza.)
- Example: Wir mögen Schwimmen. (We like swimming.)
Below is the conjugation table.
You might have noticed the patterns that the modal verbs follow in the present tense. All you need to remember is how the second vowel changes.
Rule #3 – The root form will always be the same for I, he, she, and it. The you form adds an -st ending. You plural is the original root with a -t ending. We, they, and you formal use the infinitive form of the modal verb.
In addition to dropping its umlaut in the past tense, the “g” in mögen changes to a “ch.” The pronoun endings remain the same. Below are examples in the past tense.
- Example: Ich mochte dich. (I liked you.)
- Example: Ihr mochtet Pizza. (You, plural, liked pizza.)
- Example: Wir mochten Schwimmen. (We liked swimming.)
To form the past participle, use a form of haben with gemocht.
- Example: Ich habe dich gemocht. (I liked you.)
- Example: Ihr habt Pizza gemocht. (You, plural, liked pizza.)
- Example: Wir haben Schwimmen gemocht. (We liked swimming.)
Unlike the past participle forms you've learned so far, mögen doesn't use the double infinitive form. In this case, you should always use the construction shown above.
#4 Sollen – Should
Use sollen to express what someone should do in German.
Sollen is the most regular of all the modal verbs. Notice how there is no vowel change in any of the conjugated forms.
- Example: Ich soll schlafen. (I should sleep.)
- Example: Du sollst gehen. (You should go.)
- Example: Wir sollen uns treffen. (We should meet.)
Below you'll find the conjugation table.
The simple past form of sollen has the same simple past endings as the other modal verbs so far.
- Example: Ich sollte schlafen. (I should sleep.)
- Example: Du solltest gehen. (You should go.)
- Example: Wir sollten uns treffen. (We should meet.)
Unlike the simple past tenses up to now, the meaning of sollen doesn't change in the past form. In the present tense, sollen implies how something should definitively occur. The simple past form suggests that something should happen, but might not.
Use the past participle to talk about what should have been. Most of the time, you'll use a double infinitive and the appropriate form of haben.
- Example: Ich habe schlafen sollen. (I should have slept.)
- Example: Du hast gehen sollen. (You should have gone.)
- Example: Wir haben uns treffen sollen. (We should have met.)
The form haben and gesollt is rarely used.
#5 Wollen – Want
Use wollen to describe what you want.
In the present tense, the “o” in wollen changes to “i” for the I, you, he, she, and it forms.
- Example: Ich will Schokolade essen. (I want to eat chocolate.)
- Example: Du willst einen Salat. (You want a salad.)
- Example: Wir wollen nach Hause gehen. (We want to go home.)
You'll find the conjugation table below.
Notice how the simple past is always formed by taking the root of the modal verb, removing the umlaut, and adding the appropriate ending.
The simple past pattern continues here.
- Example: Ich wollte Schokolade essen. (I wanted to eat chocolate.)
- Example: Du wolltest Salat. (You wanted salad.)
- Example: Wir wollten nach Hause gehen. (We wanted to go home.)
Form the past participle with haben and a double infinitive. Only use the combo haben and gewollt in the absence of a main verb.
- Example: Ich habe Schokolade essen wollen. (I wanted to eat chocolate.)
- Example: Du hast einen Salat gewollt. (You wanted a salad.) No main verb is present.
- Example: Wir haben nach Hause gehen wollen. (We wanted to go home.)
#6 Dürfen – May
Our final modal verb is dürfen, or may, in English. We use this verb to ask what is permitted or allowed.
In the present tense, the “ü” changes to an “a” for I, you, he, she, and it.
- Example: Ich darf Fernseh schauen. (I'm allowed to watch TV.)
- Example: Du darfst anfangen. (You may begin.)
- Example: Wir dürfen Pause machen. (We may take a break.)
You'll recognize the modal verb patterns in the table below.
You'll find examples of dürfen in the simple past below.
- Example: Ich durfte Fernseh schauen. (I was allowed to watch TV.)
- Example: Du durftest anfangen. (You were allowed to begin.)
- Example: Wir durften Pause machen. (We were allowed to take a break.)
Form the past participle by choosing the correct form of haben and a double infinitive. The form haben and gedurft is rarely used. Remember that your modal verb now comes at the end of the sentence.
- Example: Ich habe Fernseh schauen dürfen. (I was allowed to watch TV.)
- Example: Du hast anfangen dürfen. (You were allowed to begin.)
- Example: Wir haben Pause machen dürfen. (We were allowed to take a break.)

- All the modal verbs, except sollen, change their stem vowels for the pronouns I, you, he, she, and it in the present tense.
- All the modal verbs follow nearly identical conjugation patterns in the present and past tense. The only difference is the stem vowel change.
- Use the helping verb haben to form the past participle of modal verbs. In this tense, the helping verb comes first, followed by the main verb, and finally, the infinitive modal verb comes at the end.
- Modal verbs drop their umlauts in the past tenses.
- Mögen doesn't use double infinitives. Instead, use a form of haben with gemocht.
