What a Separable Verb Is
German builds verbs by adding a prefix to a base verb: stehen becomes aufstehen, kommen becomes mitkommen. In some verbs that prefix stays attached. In others it splits off and travels to the end of the clause.
Ich stehe um sieben Uhr auf.
I get up at seven. [auf- splits to the end]
Ich verstehe die Frage nicht.
I do not understand the question. [ver- never splits]
Both are perfectly regular. The difference is simply whether the prefix is separable — and that is decided by the prefix itself.
Which Prefixes Separate
The separable prefixes are almost all stressed in pronunciation, which is the most reliable test: if you stress the prefix, it separates.
Which Prefixes Never Separate
These prefixes are unstressed and stay glued to the verb in every tense and every clause type. They are also the reason some verbs have no ge- in the perfect tense.
Stress is the test
Say the verb aloud. If the stress falls on the prefix — AUFstehen, MITkommen — it separates. If the stress falls on the stem — verSTEhen, beSUchen — it never does.The Four Forms You Must Control
One verb, four shapes. This is the whole system in miniature.
Perfect tense
The participle traps the ge- inside the word: auf + ge + standen. Not geaufstanden, and not aufgestanden at position two.
Sie hat ihren Freund abgeholt.
She picked up her friend. [ab + ge + holt]
Wir sind früh eingeschlafen.
We fell asleep early. [ein + ge + schlafen]
Zu-infinitive
When you need zu with a separable verb, it goes inside the word too: Ich habe keine Zeit, einzukaufen. The same pattern appears after um … zu and ohne … zu.
Ich versuche, früher aufzustehen.
I am trying to get up earlier. [auf + zu + stehen]
Subordinate Clauses
After weil, dass, obwohl and other subordinating conjunctions, the verb goes to the end — and a separable verb comes back together there.
Ich komme später, weil ich noch einkaufen muss.
I will come later because I still have to go shopping. [Rejoined at the end after weil]
Beginners often leave the prefix stranded mid-clause here. It belongs at the very end, with the rest of the verb.
The Traps That Change Meaning
A small number of verbs exist in both a separable and an inseparable form, with different meanings. These appear in exams precisely because they are easy to confuse.
Spelling signal
When a separable verb is split, the prefix is written as a separate word and carries the stress: Ich fahre den See um. When it is inseparable, it stays joined: Ich umfahre den See.Twenty Verbs Worth Owning
Practice Sentences
Rewrite each in the perfect tense and then in a weil-clause. If both come out right, the pattern is stable.
- Ich stehe jeden Tag um sechs Uhr auf.
- Er ruft seine Mutter jeden Abend an.
- Wir kaufen am Samstag im Supermarkt ein.
- Sie kommt heute Abend mit.
- Ich mache das Fenster zu.
Perfect: Ich bin jeden Tag um sechs Uhr aufgestanden. — weil-clause: …, weil ich jeden Tag um sechs Uhr aufstehe.
Both forms keep the prefix attached to the verb; only its position changes. [Answer for 1]

Separable verbs are really a word-order topic, so read German word order next for the full verb bracket. From there, modal verbs add the infinitive-at-the-end pattern, and Konjunktiv II brings würde and hätte into the same frame.
FAQ
How do I know if a verb is separable?
Most separable prefixes are stressed, so say the verb aloud: if the stress is on the prefix (AUFstehen, MITkommen) it separates; if it is on the stem (verSTEHen, beSUchen) it does not. The prefixes be-, ge-, er-, ver-, zer-, ent-, emp- and miss- are always inseparable.
Where does ge- go in the perfect tense?
Between the prefix and the stem: aufgestanden, eingekauft, mitgebracht. Inseparable verbs take no ge- at all: verstanden, besucht, erklärt.
What happens to a separable verb in a subordinate clause?
The two parts rejoin at the end of the clause. For example: Ich komme später, weil ich noch einkaufen muss. The prefix never stays stranded in the middle of the clause.
Do separable verbs change meaning?
Usually the prefix modifies the base meaning in a predictable way, but some pairs change meaning entirely — wiederholen (repeat) versus wieder holen (fetch again), or umfahren (run over) versus um fahren (drive around).
