Modal verbs

Two verbs, one sentence: A modal verb (das Modalverb) doesn't usually stand alone — it pairs with a second verb to express ability, permission, obligation, wish or possibility. The trick that makes German modals feel strange to English speakers: the modal verb is conjugated in second position, and the main verb stays in the infinitive and jumps to the END of the clause. So «I have to study today» becomes «Ich muss heute lernen.» — muss second, lernen last. This is the Satzklammer (verb bracket): the two verbs frame the rest of the sentence.

das Modalverb

the modal verb — können, müssen, wollen, dürfen, sollen, mögen

der Infinitiv

the infinitive — the main verb stays in this form: lernen, gehen, machen

die Satzklammer

the verb bracket — modal in position 2, infinitive at the very end

die zweite Position (V2)

second position — the conjugated modal is the second element of the clause

die Modalität

modality — ability, permission, obligation, wish, possibility

mögen / möchten

to like / would like — möchten is the polite wish form of mögen

Say it as “must do”, build it as “must … do”: Whenever you want a modal sentence, picture the bracket: put the modal in slot 2 and save the infinitive for the end. «Ich kann gut Deutsch sprechen.» (I can speak German well). Get this bracket right and the most common modal mistakes disappear.

Modals are irregular in the singular: Modal verbs change their stem vowel in the singular (ich/du/er-sie-es) and — surprisingly — the ich and er/sie/es forms are identical (no -e, no -t). The plural forms (wir/sie/Sie) look like the infinitive. Learn the six singular forms below and the rest follow.

ich = er/sie/es · no -t on the modal: Two rules save you: (1) the ich form and the er/sie/es form are the same («ich kann», «er kann»), and (2) the third-person singular takes no -t («er muss», never «er musst»). Then drop the infinitive at the end: «Sie darf heute länger bleiben.» (She may stay longer today.)

möchten — the polite wish: möchten («I would like») is the most useful modal for the oral and for emails: «Ich möchte einen Termin vereinbaren.» (I'd like to make an appointment). Its forms are: ich möchte, du möchtest, er/sie/es möchte, wir möchten, ihr möchtet, sie möchten — and the infinitive still goes to the end.

Six modals, six meanings: Each modal carries a precise meaning. Choosing the right one is half the battle — «I must» (obligation) is very different from «I want» (wish) or «I may» (permission). Learn the meaning beside a German example for each.

müssen nicht vs nicht dürfen: Watch the negatives, they are NOT the same. «nicht müssen» = «don't have to» (no obligation): «Du musst nicht kommen.» (You don't have to come.) «nicht dürfen» = «must not / not allowed»: «Du darfst nicht rauchen.» (You must not smoke.) Mixing these up changes the whole meaning.

Plans and rules, sentence by sentence: Here is a short paragraph about a weekend, built one sentence at a time. Every sentence uses a modal verb: modal in position 2, infinitive at the end. Read it once for meaning, then tap Übersetzung anzeigen for the English or 🔊 to hear it.

Steal this to talk about plans and rules: Notice the recipe: subject + modal (slot 2) + … + infinitive (end). Use wollen/möchten for what you want, müssen for what you have to do, dürfen for what's allowed, können for what you're able to do. Swap in your own weekend and you have a ready-made paragraph about plans.

The slips to watch for: Three mistakes dominate: conjugating the second verb instead of leaving it as an infinitive («ich will gehe» → «ich will gehen»); leaving the infinitive in the middle instead of sending it to the end; and adding «zu» before the infinitive (modals never take «zu»). Compare the right version with the typical mistake.

Modal second, infinitive last, no «zu»: Before you write a modal sentence, check the bracket: the modal is in position 2, the infinitive is at the end, and there is no «zu» between them. For the third-person singular, remember no -t («er muss», «sie kann»).
