German Separable Verbs: How They Work and Why They Split
Why German verbs split in two — and when they stay together.
German separable verbs look intimidating at first: you learn "aufmachen" (to open) but then see "Ich mache die Tür auf" — the verb has split in two! Understanding why makes the whole system logical.
Common Separable Prefixes
The most common separable prefixes each add a specific meaning:
- 1auf- = up, open (aufmachen = to open, aufstehen = to get up)
- 2ab- = away, off (abfahren = to depart, absagen = to cancel)
- 3an- = on, at (ankommen = to arrive, anrufen = to call)
- 4aus- = out (ausgehen = to go out, ausschalten = to turn off)
- 5ein- = in (einschlafen = to fall asleep, einkaufen = to shop)
The Splitting Rule
In a main clause present tense, the prefix separates and moves to the END of the sentence: "Ich stehe um 7 auf" (I get up at 7). "Er ruft seine Mutter an" (He calls his mother). In an infinitive after a modal verb, the verb stays together: "Ich muss früh aufstehen" (I must get up early).
Separable vs. Inseparable Prefixes
Some prefixes never separate: be-, ge-, er-, ver-, zer-, ent-, emp-, miss-. "Ich besuche" (I visit) — never "Ich suche... be". A quick test: if the prefix is stressed when you say the infinitive, it is separable.
