Rules and usage
Separable and inseparable verbs are a fundamental feature of German that changes how the verb appears in a sentence depending on whether you use the infinitive, a conjugated form, or a past participle. Understanding which prefix stays attached and which separates from the verb stem is essential for correct German word order and meaning.
What Are Separable and Inseparable Verbs
Separable verbs have a prefix that detaches from the verb stem when the verb is conjugated in main clauses. The prefix moves to the end of the clause, while the conjugated verb stays in its normal position. Inseparable verbs have a prefix that never separates from the verb stem, no matter how the sentence is structured. The prefix remains permanently attached.
