Modal verbs (modale werkwoorden) in Dutch are special verbs that express ability, possibility, necessity, permission, or obligation. They help change the meaning of the main verb in a sentence.
Use modal verbs in Dutch to talk about what someone can, must, may, wants, or will do. They are used before another verb, which is placed at the end of the sentence.
