Passiversatz – Structures That Replace the Passive

Passiversatzformen carry the meaning of the "werden" passive but look active grammatically, and most of them mean "können" (can be done). The key is being able to turn these patterns into the passive in your head as soon as you see them.

📌
Golden rule: The most common three: sein + zu + Infinitiv, sich lassen + Infinitiv and the -bar adjective ("Das ist lösbar = Das kann gelöst werden").
