Modal Verb and Infinitive

Level 1

Modal in second place, infinitive at the end: Ech kann haut net kommen.

How It Works

The frame
The modal and the infinitive form a frame around the rest of the sentence:

  • Statement: Mir mussen elo goen.
  • Time first: Muer muss ech fréi opstoen.
  • Yes/no question: Wëlls du eppes drénken?
  • Question word: Wat wëllt Dir iessen?

This is the same verb-second rule as in word order basics and yes/no questions.

Where net goes
Net usually comes just before the infinitive: Ech kann haut net kommen.

Separable verbs stay together
In the infinitive, a separable verb is one word at the end: Kanns du d'Fënster zoumaachen? (not maachen ... zou).

No ze
Modal verbs take a bare infinitive. Other verbs sometimes need ze, but kënnen, mussen and wëllen never do.

Coming later
In a subordinate clause, the conjugated modal usually comes just before the infinitive at the end: ..., datt ech muer muss schaffen. See modals in subordinate clauses.

Examples (6)

  1. Ech kann haut net kommen.

    I can't come today.

    Word by Word: I can today not come.

    Net comes right before the infinitive.

  2. Mir mussen elo goen.

    We have to go now.

    Word by Word: We must now go.

  3. Wëlls du eppes drénken?

    Do you want something to drink?

    Word by Word: Want you something drink?

    In a yes/no question the modal comes first.

  4. Wat wëllt Dir iessen?

    What do you want to eat?

    Word by Word: What want you eat?

    Polite Dir; the question word is first and the modal second.

  5. Muer muss ech fréi opstoen.

    Tomorrow I have to get up early.

    Word by Word: Tomorrow must I early up-stand.

    The separable verb opstoen stays in one piece at the end.

  6. Kanns du d'Fënster zoumaachen?

    Can you close the window?

    Word by Word: Can you the window close?

Common Mistakes

  • Putting the infinitive next to the modal.

    Ech ka kommen haut net.
    Ech kann haut net kommen.

    The infinitive goes to the end of the clause; other words come between the two verbs.

  • Adding ze after a modal verb.

    Ech muss ze schaffen.
    Ech muss schaffen.

    Kënnen, mussen and wëllen take the infinitive without ze.

  • Conjugating the second verb as well.

    Hie ka schwëmmt.
    Hie ka schwammen.

    Only the modal is conjugated. The second verb stays in the infinitive: schwammen, not schwëmmt.
