Separable Verb Prefixes (an-, auf-, aus-, ein-, mit-, vor-, zu-)

If the inseparable prefixes are welded on, the separable prefixes are clip-ons: stressed, meaning-rich, and able to fly off to the end of the clause. They behave almost exactly like English phrasal-verb particles — get *up, turn off, come along* — except German writes them solid in the infinitive (aufstehen, ausmachen, mitkommen) and detaches them in a main clause. This page is about what each particle means, so you can read and build separable verbs the way an English speaker intuits take off vs take out vs take over.

The two behaviours that define them

Two facts separate these prefixes from the inseparable ones (which never move and carry no stress):

1. They are stressed. Say ÁNrufen, ÁUFstehen, ÉINkaufen — the prefix carries the beat. This is the diagnostic.
2. They split in a main clause. The conjugated verb sits in second position (V2) and the prefix drops to the very end, framing the sentence. This frame is the Satzklammer (sentence bracket).

Everything between the verb and the flung-off prefix is held inside the bracket, which is why the prefix is often the last thing you hear — and why missing it changes the meaning entirely (Ich rufe dich an = I'll call you; Ich rufe dich = I'm calling out to you).

The core particle meanings

Each separable prefix has a fairly transparent spatial or directional core, which then extends to idiomatic uses — exactly like English particles.

The particle system in action: machen + particle

The most convincing demonstration that this is a system, not a list to memorize, is to keep one base verb and swap particles. Take machen (do/make):

This is identical in spirit to English turn *on / turn off / turn up*. If you know the particle, you can predict the verb. The same works for kommen (come): ankommen (arrive), mitkommen (come along), zurückkommen (come back), rauskommen (come out). And for steigen (climb/board): einsteigen (board), aussteigen (get off), umsteigen (change/transfer).

When the meaning goes idiomatic

Like English phrasal verbs (give up has nothing to do with up), many separable verbs are idiomatic and must be learned as wholes. The particle gives a hint, not a guarantee:

• aufgeben = give up (literally "give up," but means surrender/quit, just as in English)
• vorstellen = to introduce / to present; sich vorstellen = to imagine ("place before one's mind")
• vorhaben = to plan, intend ("have before one")
• stattfinden = to take place (literally "find place," idiomatic)

The participle and the zu-infinitive

Because the prefix is its own meaningful unit, German tucks the participle marker ge- inside it. The participle of a separable verb is prefix + ge + stem-participle: anrufen → angerufen, aufstehen → aufgestanden, einkaufen → eingekauft.

With zu, the zu slips into the same slot, between prefix and stem: anrufen → anzurufen, einkaufen → einzukaufen. (See the separable-verbs-with-zu page for the full picture.)

This is the mirror image of the inseparable prefixes, where ge- is omitted and zu sits before the whole verb. Putting the two pages side by side is the fastest way to internalize both systems.

A note on the "both" prefixes

A few prefixes — durch-, über-, um-, unter-, wieder-/wider-, hinter- — can be either separable or inseparable, with stress as the guide and usually a literal-vs-figurative meaning split. The classic pair:

• úmfahren (separable, stress on prefix) = to run over / knock down: Er fährt das Schild um. (He knocks the sign over.)
• umfáhren (inseparable, stress on stem) = to drive around: Er umfährt das Schild. (He drives around the sign.)

These deserve their own treatment — see the dual-prefix page — but it's worth knowing the boundary between separable and inseparable isn't always crisp.

Common Mistakes

In a main clause the separable prefix detaches: the conjugated stem (rufe) goes to V2, and an lands at the end. Keeping them joined is the number-one separable-verb error.

The participle infixes ge-: auf + ge + standen = aufgestanden. (And aufstehen takes sein, not haben, because it's a change of position.)

The zu slots between prefix and stem: anzurufen, not zu anrufen and not a bare infinitive.

The particle carries the meaning. Drop zu and you've said "make the window," which is nonsense. Always remember to send the particle to the end.

In a subordinate clause (after weil, dass, wenn…) the whole verb goes to the end and the prefix re-attaches: aufstehe, not split.

Key Takeaways

• Separable prefixes are stressed and carry transparent, particle-like meaning (an-, auf-, aus-, ein-, mit-, vor-, zu-, ab-, weg-, zurück-).
• In a main clause they split, with the prefix flung to the clause end (Satzklammer); in subordinate clauses they rejoin at the end.
• The participle infixes ge- (angerufen) and zu slips inside (anzurufen) — the exact opposite of inseparable prefixes.
• The system is productive: swap particles on one base verb (machen → aufmachen/zumachen/anmachen/ausmachen) much like English phrasal verbs.
• Many are idiomatic (aufgeben = give up; vorstellen = introduce/imagine) and must be learned whole; the dual prefixes (um-, über-…) can go either way.
