What you’ll be able to do
After this lesson, you will be able to express ability, obligation, desire and preference in German. You will use können (can), müssen (must), wollen (want) and mögen (like) to talk about what you are able to do, what you have to do, what you want to do and what you enjoy doing. You will also place the main verb at the end of the sentence, which is the key structural rule for modal verbs.
The idea
Modal verbs modify another verb. They tell you something about the action: whether it is possible, necessary, wanted or liked. In English, you say “I can swim” or “I must go”. German works the same way, but with one important difference: the second verb always goes to the end of the sentence in its infinitive form.
Think of it as a frame. The modal verb takes the second position, conjugated for the subject. The infinitive sits at the very end. Everything else goes in between. This is called the “sentence bracket” or Satzklammer, and it is one of the most important patterns in German grammar.
The four verbs you learn here are the most common modals at A1 level. Each one has a distinct meaning, and together they cover most everyday situations: ability, obligation, desire and preference. Once you master these four, you will already handle a large part of daily conversation.
See it in German
Notice how the modal verb is always in second position and the infinitive is always at the end. Read each sentence aloud and feel the rhythm of the frame.
- Ich kann Deutsch sprechen. (I can speak German.)
- Wir müssen morgen früh aufstehen. (We must get up early tomorrow.)
- Er will einen neuen Job finden. (He wants to find a new job.)
- Sie mag italienisches Essen. (She likes Italian food.)
- Können Sie mir helfen? (Can you help me?)
- Ich muss heute Abend arbeiten. (I must work this evening.)
- Wir wollen nächste Woche umziehen. (We want to move next week.)
- Die Kinder mögen nicht früh schlafen gehen. (The children do not like to go to sleep early.)
- Du kannst den Brief aufgeben. (You can post the letter.)
- Er muss den Vertrag lesen. (He must read the contract.)
Two things to notice. First, the infinitive at the end is never conjugated. It stays in its base form: sprechen, aufstehen, finden, helfen. Second, in a yes-or-no question, the modal verb moves to first position and the subject follows it: Können Sie mir helfen? This is the same pattern you already know from other verb-first questions.
Read it in the wild
Now that you know the pattern, find it in real German text. Go to the A1 or A2 version of any news article on this site. Every article has a vocabulary box and a simplified German version designed for learners. Your task: find every modal verb in the text and underline it. Then check which infinitive sits at the end of that clause.
For example, in an article about daily routines you might find: Man muss jeden Tag früh aufstehen. Circle müssen and point to aufstehen at the end. Do this for every modal verb you find. This trains your eye to recognise the sentence bracket automatically, which is exactly what fluent readers do.
If you want a structured place to start, look for articles tagged with daily life or routines on this site. These topics naturally use obligation and ability, so you will find plenty of müssen and können. Aim to read at least one full article this week and identify every modal construction. Remember: you need to know 95 to 98 percent of the words in a text to absorb new grammar from context, so choose an A1 text if you are still building confidence.
Common mistakes
Here are the errors learners make most often with modal verbs, and how to fix them.
- Putting the infinitive in the wrong place. You might write Ich kann sprechen Deutsch. This is wrong. The infinitive must go to the end: Ich kann Deutsch sprechen. The rule is strict. Every time.
- Conjugating the infinitive. You might write Wir müssen arbeiten but then be tempted to add an ending to arbeiten. Do not. The infinitive never changes. Wir müssen arbeiten is correct. Wir müssen arbeiten stays arbeiten, no matter the subject.
- Confusing mögen and gern. Mögen takes a noun or an infinitive. Ich mag Kaffee or Ich mag Kaffee trinken. Do not say Ich mag trinken Kaffee. The word order still matters. Also, remember that gern is a separate word used with verbs: Ich trinke gern Kaffee. Both express preference, but the structure is different.
- Forgetting the umlaut in können. The infinitive is können, but the er/sie/es form is kann. The umlaut drops in singular forms. Write kann, not könnt for er/sie/es. The plural wir können keeps the umlaut.
- Using müssen when sollen is correct. Müssen expresses a strong obligation or necessity: Ich muss zum Arzt (I must go to the doctor). Sollen is weaker, more like “should” or “am supposed to”: Ich soll mehr Wasser trinken (I should drink more water). At A1, focus on müssen for clear necessity, and do not worry about sollen yet.
Where you are now
This is lesson 23 of 49. You have just moved from describing your home to describing what you can, must, want and like to do. That is a significant step. You are no longer just naming things; you are expressing your relationship to actions and obligations. In the previous lesson, Describe Your Home in German, you practised vocabulary for rooms and furniture. Now you can combine that with modal verbs: Ich möchte ein größeres Zimmer mieten (I would like to rent a larger room). The next lesson, Separable Verbs: Why the Verb Splits in Two, will teach you another essential sentence structure. Many separable verbs combine with modals, so what you learn here will pay off immediately.
