Past Participles of Weak Verbs (ge-...-t) | German Grammar

The past participle is the form that pairs with haben or sein to build the Perfekt — the everyday spoken past in most of Germany. Weak verbs are the largest and most predictable group: their participle is a clean formula, ge- + stem + -t. Master this one pattern and you can form the past of thousands of verbs, including every brand-new verb German borrows from English.

The core formula: ge- + stem + -t

Take the infinitive, chop off the -en (or -n) ending to get the stem, then wrap it in ge- at the front and -t at the back.

Infinitive	Stem	Participle	Meaning
machen	mach-	gemacht	made / done
spielen	spiel-	gespielt	played
kaufen	kauf-	gekauft	bought
sagen	sag-	gesagt	said
fragen	frag-	gefragt	asked
wohnen	wohn-	gewohnt	lived (resided)
lernen	lern-	gelernt	learned
hören	hör-	gehört	heard

The participle never changes its ending to agree with the subject — unlike adjectives, it sits frozen at the end of the clause. Whether the subject is ich, du, or wir, the participle stays gemacht.

Was hast du am Wochenende gemacht?

What did you do over the weekend?

Wir haben gestern bis Mitternacht Karten gespielt.

We played cards until midnight yesterday.

Ich habe ihr schon dreimal gesagt, dass ich keine Zeit habe.

I've already told her three times that I don't have time.

💡

The verb that carries the meaning (the participle) goes to the very end of the main clause; the auxiliary haben or sein sits in the normal second-position verb slot. This "bracket" — auxiliary near the front, participle at the end — is one of the defining shapes of a German sentence.

The linking -e- after t- and d-stems

If the stem already ends in -t or -d (and a few other clusters), you cannot pronounce a bare -t right on top of it. German inserts a linking -e- to keep the ending audible: the ending becomes -et.

Infinitive	Stem	Participle	Meaning
arbeiten	arbeit-	gearbeitet	worked
reden	red-	geredet	talked
warten	wart-	gewartet	waited
öffnen	öffn-	geöffnet	opened
regnen	regn-	geregnet	rained
kosten	kost-	gekostet	cost

The rule isn't really "after t and d" — it's "wherever a bare -t would be impossible or unpronounceable to say." That covers stems ending in -t, -d, and consonant clusters like -fn- (öffnen) and -gn- (regnen). Trust your ear: if geöffnt feels like a tongue-twister, that's because it is — hence geöffnet.

Ich habe heute zehn Stunden gearbeitet und bin total erledigt.

I worked ten hours today and I'm completely wiped out.

Wir haben über eine Stunde auf den Bus gewartet.

We waited over an hour for the bus.

Hast du schon das Fenster geöffnet? Hier ist es so stickig.

Have you already opened the window? It's so stuffy in here.

When ge- disappears: -ieren verbs

Verbs ending in -ieren — almost all of them borrowed from French, Latin, or English — form their participle with no ge- at all. The participle is simply the stem plus -t.

Infinitive	Participle	Meaning
studieren	studiert	studied (at university)
telefonieren	telefoniert	phoned
fotografieren	fotografiert	photographed
reservieren	reserviert	reserved
passieren	passiert	happened
funktionieren	funktioniert	worked / functioned

Ich habe in Heidelberg Medizin studiert.

I studied medicine in Heidelberg.

Was ist denn passiert? Du siehst ganz blass aus.

What on earth happened? You look completely pale.

When ge- disappears: inseparable-prefix verbs

The same gap appears with weak verbs that begin with an inseparable prefix — be-, emp-, ent-, er-, ge-, ver-, zer-. These never take a ge- in the participle either.

Infinitive	Participle	Meaning
besuchen	besucht	visited
verkaufen	verkauft	sold
bezahlen	bezahlt	paid
erklären	erklärt	explained
erzählen	erzählt	told (a story)
verdienen	verdient	earned

Meine Oma hat uns gestern besucht und Kuchen mitgebracht.

My grandma visited us yesterday and brought cake along.

Hast du die Rechnung schon bezahlt?

Have you already paid the bill?

Why ge- comes and goes: it follows the stress

Here is the insight most courses skip. The ge- is not random — it attaches only when the verb is stressed on its very first syllable. Say the verbs out loud:

MAchen, KAUfen, SPIElen — stress on the first syllable → ge- appears: gemacht, gekauft, gespielt.
stuDIEren, telefoNIEren — stress on -ier-, not the front → no ge-: studiert, telefoniert.
beSUchen, verKAUfen, erKLÄren — stress on the second syllable (the inseparable prefix is unstressed) → no ge-: besucht, verkauft, erklärt.

So the prefix ge- is itself an unstressed syllable that only docks onto a stressed stem. When the stress has already moved off the front of the word (as in -ieren verbs and inseparable-prefix verbs), there is no stressed front syllable for ge- to attach to, and it simply doesn't appear. Once you hear the stress, you can predict the participle without memorizing lists.

💡

If you're unsure whether a verb takes ge-, say it aloud and find the stressed syllable. Stress on the first syllable → ge-. Stress anywhere else → no ge-. This single test handles weak, strong, and prefixed verbs alike.

How English speakers trip up

English has only one regular past form (-ed) and no prefix that comes and goes, so the German ge- feels like an extra decoration you can sprinkle anywhere. It isn't.

❌ Ich habe in Berlin gestudiert.

Incorrect — -ieren verbs never take ge-.

✅ Ich habe in Berlin studiert.

I studied in Berlin.

❌ Wir haben unsere Tante gebesucht.

Incorrect — inseparable be- verbs never take ge-.

✅ Wir haben unsere Tante besucht.

We visited our aunt.

❌ Ich habe acht Stunden gearbeit.

Incorrect — a t/d-stem needs the linking -e-.

✅ Ich habe acht Stunden gearbeitet.

I worked eight hours.

❌ Sie hat das Fenster geöffnt.

Incorrect — the -fn- cluster needs the linking -e-.

✅ Sie hat das Fenster geöffnet.

She opened the window.

❌ Er hat mir die Aufgabe geerklärt.

Incorrect — er- is inseparable, so no ge- (and certainly not ge- + er-).

✅ Er hat mir die Aufgabe erklärt.

He explained the task to me.

Key takeaways

Weak participle = ge- + stem + -t (gemacht, gespielt, gekauft).
After a t-/d-stem or an awkward cluster, the ending becomes -et (gearbeitet, geöffnet).
-ieren verbs take no ge- (studiert, telefoniert).
Inseparable-prefix verbs take no ge- (besucht, verkauft, erklärt).
The deciding factor is stress: ge- only docks onto a verb stressed on its first syllable.

Once the weak pattern is automatic, move on to the strong participles, where the same ge- rules apply but the ending is -en and the stem vowel often changes.
