Introduction

German inseparable verbs, known as untrennbare Verben, are a fundamental aspect of the German language. These verbs have prefixes that remain attached to the base verb in all tenses and sentence structures. Understanding inseparable verbs is crucial for mastering German grammar and enhancing your fluency. This guide will explain what inseparable verbs are, how to recognize them, and how to conjugate them in different tenses.

Understanding German Inseparable Verbs

Inseparable verbs are verbs that begin with specific prefixes that do not detach from the base verb. These prefixes alter the meaning of the base verb but always stay connected, regardless of the tense or sentence structure. The meaning of the verb often changes significantly with the addition of the prefix. Example: verstehen (to understand)
  • Ich verstehe dich. – I understand you.
