Special features of the modal verbs


Modal verbs dürfen, können, mögen, müssen, sollen and wollen govern the infinitive of a full verb and can have no additional complements (e.g. an object). The infinitive that is connected to a modal verb is not preceded by the word zu.


Examples complement case governed by the full verb
Ich kann dir nicht helfen. dir = dative object helfen + dative
Peter will seine Oma besuchen. seine Oma = accusative object besuchen + accusative


Modal verbs can be combined with other modal verbs.
