Purpose
By the end of this lesson, you will be able to correctly conjugate and use three common German modal verbs.
Lesson Explanation
Modal verbs add a specific meaning to another verb, and are genuinely irregular in the present tense, with distinctive singular forms:
können (can/to be able to): ich kann, du kannst, er kann, wir können, ihr könnt, sie können müssen (must/to have to): ich muss, du musst, er muss, wir müssen, ihr müsst, sie müssen wollen (to want to): ich will, du willst, er will, wir wollen, ihr wollt, sie wollen
A modal verb is followed by the main verb in its infinitive form, placed at the very end of the sentence — directly connecting to the separated-prefix placement from Lesson 5, both putting a meaning-bearing element at the sentence’s end: Ich kann Deutsch sprechen. (I can speak German.)
A genuinely important, specific pattern: notice ich and er/sie/es use the identical form for all three verbs (kann, muss, will) — a consistent irregularity across this whole verb category.
