A Danish verb can end in -s for three main reasons. Learn the difference so you don't mistake ordinary -s verbs for the passive. |
The -s passive is common in signs, headlines and instructions. It describes what happens to someone/something. |
Form: present passive = present form + -s (laver → laves). Passive infinitive also ends in -s (at laves), especially after modals (kan laves, skal laves). |
If you want to name the doer, it's often clearer to use blive-passive: Dokumentet blev sendt af Maria = The document was sent by Maria. |
