Once a verb carries a prefix — auf-, an-, ein-, be-, ver-, ent- — the question becomes: where does the -ge- go in the participle? German has a beautifully consistent answer. With separable verbs the -ge- slots between the prefix and the stem; with inseparable verbs it disappears entirely. And both behaviors are predicted by one thing you can hear: where the stress falls.
Separable verbs: -ge- goes in the middle
A separable verb (the prefix is stressed and can detach in a main clause) keeps its ge-, but the ge- attaches to the stem, so the prefix ends up in front of it. The structure is prefix + -ge- + stem + ending.
| Infinitive | Participle | Meaning |
|---|---|---|
| aufstehen | aufgestanden | got up |
| ankommen | angekommen | arrived |
| einkaufen | eingekauft | shopped |
| mitbringen | mitgebracht | brought along |
| anrufen | angerufen | called (phone) |
| fernsehen | ferngesehen | watched TV |
| aufmachen | aufgemacht | opened |
Crucially, the strong/weak/mixed identity of the base verb is untouched. Aufstehen contains strong stehen (gestanden), so the participle is aufgestanden. Einkaufen contains weak kaufen (gekauft), so it's eingekauft. The prefix just rides along in front; build the base participle first, then bolt the prefix onto its front.
Ich bin heute extra früh aufgestanden, um den Sonnenaufgang zu sehen.
I got up especially early today to see the sunrise.
Der Zug ist mit zwanzig Minuten Verspätung angekommen.
The train arrived twenty minutes late.
Hast du für das Wochenende schon eingekauft?
Have you already done the shopping for the weekend?
Meine Mutter hat gestern Abend angerufen und nach dir gefragt.
My mother called last night and asked about you.
Inseparable verbs: no -ge- at all
An inseparable verb (the prefix is unstressed and stays glued to the stem in every form) takes no ge- whatsoever. The participle is just prefix + stem + ending. The inseparable prefixes are a fixed set: be-, emp-, ent-, er-, ge-, miss-, ver-, zer-.
| Infinitive | Participle | Meaning |
|---|---|---|
| verstehen | verstanden | understood |
| bekommen | bekommen | received |
| erklären | erklärt | explained |
| entscheiden | entschieden | decided |
| besuchen | besucht | visited |
| vergessen | vergessen | forgotten |
| empfehlen | empfohlen | recommended |
The base verb's strong/weak identity still shows: erklären is weak, so erklärt with -t; verstehen is strong, so verstanden with a changed vowel and -en. The only thing the inseparable prefix removes is the ge-.
Ich habe endlich verstanden, wie diese Maschine funktioniert.
I finally understood how this machine works.

We received a parcel from Japan today.

Nach langem Hin und Her haben wir uns für das blaue Sofa entschieden.

The one rule behind both: -ge- follows the stress
This is the insight that makes the whole system click — and it's the one most courses leave out. The prefix ge- is itself an unstressed syllable, and unstressed ge- can only dock directly in front of a stressed stem.
- In a separable verb, the prefix is stressed (AUFstehen, ANkommen). The stressed stem sits behind the prefix, so ge- lands there too: AUFgestanden, ANgekommen — ge- in the middle.
- In an inseparable verb, the stem is stressed and the prefix is unstressed (verSTEHen, beKOMmen). There's no stressed syllable at the front for ge- to attach to, so ge- simply doesn't appear: verstanden, bekommen.
Say a prefixed verb aloud and find the stress. Stress on the prefix → separable → -ge- in the middle. Stress on the stem → inseparable → no ge-. The stress test predicts the participle every single time.
Stacking it together
Plenty of everyday verbs combine a separable prefix with a strong or mixed base. Work from the inside out: take the base participle, then attach the prefix.
| Base + prefix | Base participle | Full participle |
|---|---|---|
| kommen → mitkommen | gekommen | mitgekommen |
| bringen → mitbringen | gebracht | mitgebracht |
| laden → einladen | geladen | eingeladen |
| nehmen → mitnehmen | genommen | mitgenommen |
| ziehen → anziehen | gezogen | angezogen |
Wir haben alle Nachbarn zur Grillparty eingeladen.
We invited all the neighbors to the barbecue.
Bist du am Ende doch mitgekommen?
Did you end up coming along after all?
Der Minister hat die Reform vorgestellt, ohne die Kosten zu nennen.
The minister presented the reform without naming the costs. (formal/news register)
A useful sanity check: the -ge- of a separable participle lands in exactly the spot where, in an infinitive with zu, the zu would sit. Compare aufzustehen ("to get up") with aufgestanden — the zu and the ge occupy the same slot, wedged between the prefix and the stem. If you can place the zu, you can place the ge.
How English speakers trip up
English has no movable prefix and no ge-, so two opposite errors are common: putting ge- at the front of a separable verb (as if the prefix weren't there), or sprinkling ge- onto an inseparable verb out of habit.
❌ Ich bin um sechs Uhr geaufstanden.
Incorrect — separable: the -ge- goes inside, after the prefix: aufgestanden.
✅ Ich bin um sechs Uhr aufgestanden.
I got up at six o'clock.
❌ Wir haben das Paket gebekommen.
Incorrect — inseparable be-: no ge- at all: bekommen.
✅ Wir haben das Paket bekommen.
We received the parcel.
❌ Sie hat mich gestern geanrufen.
Incorrect — separable an-: -ge- goes in the middle: angerufen.
✅ Sie hat mich gestern angerufen.
She called me yesterday.
❌ Er hat mir den Weg geerklärt.
Incorrect — inseparable er-: no ge-: erklärt.
✅ Er hat mir den Weg erklärt.
He explained the way to me.
❌ Wir haben gestern Lebensmittel geeingekauft.
Incorrect — the -ge- already sits inside (ein + ge + kauft); never add a second ge- at the front.
✅ Wir haben gestern Lebensmittel eingekauft.
We bought groceries yesterday.
Key takeaways
- Separable verbs put -ge- in the middle: prefix + ge
- stem (aufgestanden, angekommen, eingekauft).
- Inseparable verbs (be-, emp-, ent-, er-, ge-, miss-, ver-, zer-) take no ge- at all (verstanden, bekommen, erklärt).
- The prefix never changes the base verb's strong/weak identity — build the base participle, then attach the prefix.
- One rule covers everything: -ge- follows the stress. Stressed prefix → -ge- in the middle; unstressed prefix → no ge-.
