Why This Matters

Modal verbs are the backbone of expressing nuance in German—they tell your listener not just what you're doing, but why, whether you're allowed to, or how badly you want to. On the AP German exam, you're being tested on your ability to communicate with precision across contexts: discussing family dynamics, cultural expectations, environmental responsibilities, and personal aspirations. Modal verbs appear constantly in interpersonal writing, presentational speaking, and reading comprehension because they reveal attitudes, obligations, and social relationships.

Think of modals as the verbs that add social and emotional color to your German. When you read about Elternzeit policies or Umweltschutz debates, modal verbs signal who must comply, who may participate, and who wants change. Don't just memorize conjugation tables—know what communicative function each modal serves and when to deploy it for maximum clarity and cultural appropriateness.


Expressing Ability and Permission

These modals address what someone can or is allowed to do. The distinction matters: ability is about capacity, while permission involves social or institutional authorization.

Können (can, to be able to)

  • Indicates ability or capability—use this when describing skills or physical capacity (Ich kann Deutsch sprechen)
  • Expresses informal permission—in casual contexts, können often replaces dürfen (Kannst du mir helfen?)
  • Stem-changing conjugation: ich kann, du kannst, er/sie/es kann, wir können, ihr könnt, sie/Sie können

Dürfen (may, to be allowed to)

  • Signals formal permission or prohibition—essential for discussing rules, laws, and institutional policies
  • Carries moral or ethical weight—often implies rightness, not just allowance (Das darf man nicht tun)
  • Conjugation pattern: ich darf, du darfst, er/sie/es darf, wir dürfen, ihr dürft, sie/Sie dürfen

Compare: Können vs. Dürfen—both can translate to "can" in English, but können emphasizes ability while dürfen emphasizes permission. On the exam, choosing the wrong one signals a misunderstanding of social context. FRQ tip: When writing about regulations (Umweltgesetze, Familienrecht), dürfen is almost always the correct choice.


Expressing Necessity and Obligation

These modals convey what someone must or should do. The difference lies in the source and strength of the obligation.

Müssen (must, to have to)

  • Expresses strong necessity or obligation—there's typically no alternative (Ich muss morgen arbeiten)
  • Common in legal, institutional, and time-sensitive contexts—rules, deadlines, and requirements
  • Conjugation pattern: ich muss, du musst, er/sie/es muss, wir müssen, ihr müsst, sie/Sie müssen

Sollen (should, ought to)

  • Indicates external expectation or recommendation—the obligation comes from someone else or social norms
  • Used for advice, suggestions, and reported instructionsDer Arzt sagt, ich soll mehr schlafen
  • Conjugation pattern: ich soll, du sollst, er/sie/es soll, wir sollen, ihr sollt, sie/Sie sollen

Compare: Müssen vs. Sollenmüssen is internal or absolute necessity (you have no choice), while sollen reflects external expectations (someone thinks you should). When discussing family responsibilities or cultural duties, sollen often captures the social pressure aspect better than müssen.


Expressing Desire and Preference

These modals communicate what someone wants or likes. They reveal personal agency, intentions, and emotional responses.

Wollen (want to)

  • Expresses strong desire or intention—conveys determination and personal will (Ich will Medizin studieren)
  • Used for future plans and aspirations—common in discussions of goals and ambitions
  • Conjugation pattern: ich will, du willst, er/sie/es will, wir wollen, ihr wollt, sie/Sie wollen

Mögen (to like)

  • Indicates general liking or preference—often used with nouns rather than infinitives (Ich mag Kaffee)
  • Subjunctive form möchten expresses polite wishesIch möchte einen Kaffee, bitte (I would like...)
  • Conjugation pattern: ich mag, du magst, er/sie/es mag, wir mögen, ihr mögt, sie/Sie mögen

Compare: Wollen vs. Mögen/Möchtenwollen is direct and assertive (I want), while möchten is polite and softened (I would like). In interpersonal communication tasks, using möchten instead of wollen demonstrates cultural awareness of German politeness norms. This distinction frequently appears in dialogue-based reading passages.


Understanding word order with modals is critical for accurate production. The modal verb takes the conjugated position, and the infinitive moves to the end.

Standard Word Order

  • Modal conjugates in position 2—the main verb appears as an infinitive at the sentence end (Ich kann heute nicht kommen)
  • In questions, modal moves to position 1Kannst du mir helfen? or Darf ich fragen?
  • In subordinate clauses, modal moves to final position...weil ich morgen arbeiten muss

Compare: German vs. English word order—English keeps verbs together (I can come), but German separates them (Ich kann... kommen). This bracket structure (Satzklammer) is a common error source. Practice until the infinitive-at-the-end pattern feels automatic.

Self-Check Questions

  1. Which two modal verbs can both translate to "can" in English, and what distinguishes their usage in German?

  2. You're writing about Germany's Kohleausstiegsgesetz (coal phase-out law). Would you use müssen or sollen to describe what companies are required to do, and why?

  3. Compare wollen and möchten: In what social context would choosing one over the other demonstrate cultural competence?

  4. A reading passage describes family communication: Die Kinder sollen ihre Großeltern regelmäßig anrufen. What does the use of sollen reveal about the source of this expectation?

  5. Construct a sentence about environmental policy using dürfen in the negative to express a prohibition. How does word order change if you embed this in a weil-clause?
