The German present participle — Partizip I — is one of the most over-applied forms by English speakers, because it looks like the English -ing ending and learners reflexively reach for it to build a progressive tense. It cannot do that. Partizip I is purely adjectival and adverbial: it describes things and modifies actions, but it is never a verb form on its own. Once you accept that German has no continuous tense, the form falls neatly into place.
How to form it
Partizip I is the simplest participle in German: take the infinitive and add -d.
| Infinitive | Partizip I | Meaning |
|---|---|---|
| lachen | lachend | laughing |
| schlafen | schlafend | sleeping |
| kochen | kochend | boiling / cooking |
| weinen | weinend | crying |
| steigen | steigend | rising |
There are only two tiny irregularities: sein → seiend and tun → tuend, both rare.
Use 1: as an attributive adjective
The main job of Partizip I is to sit in front of a noun like an adjective and take normal adjective endings. It describes the noun as performing the action right now — an active, ongoing quality.
Das lachende Kind rannte über die Wiese.
The laughing child ran across the meadow. — lachend + weak ending -e after das.
Ein schlafender Hund liegt vor dem Kamin.
A sleeping dog is lying in front of the fireplace. — schlafend + strong ending -er after ein.
Vorsicht, kochendes Wasser!
Careful, boiling water! — kochend + ending -es for neuter Wasser.
The crucial point: it declines exactly like any adjective (das lachende Kind, ein lachendes Kind, dem lachenden Kind), because functionally it is an adjective.
Use 2: as an adverb of manner
Partizip I can also stand uninflected and describe how an action is performed — the manner accompanying the main verb. English handles this with -ing too, which is why it feels familiar: "She came in laughing."
Sie kam lachend ins Zimmer.
She came into the room laughing.
Er verließ wortlos und kopfschüttelnd den Raum.
He left the room without a word, shaking his head. (literary)
Die Kinder rannten schreiend durch den Garten.
The children ran screaming through the garden.
Here the participle is invariable — no endings — because it modifies a verb, not a noun.
Use 3: the gerundive (zu + Partizip I)
In formal and especially written German, zu plus Partizip I forms a gerundive that expresses something that must or can be done — a passive-like obligation. It declines as an attributive adjective and replaces a relative clause.
Die zu lösende Aufgabe ist sehr schwer.
The task to be solved is very difficult. (formal) — equals 'die Aufgabe, die gelöst werden muss'.
Das sind die noch zu klärenden Fragen.
Those are the questions still to be clarified. (formal/academic)
This construction belongs to administrative, legal, and academic register; it sounds out of place in casual speech.
Why Partizip I is NOT a tense
Here is the single most important fact, and the one competitors gloss over: German has no continuous aspect. There is no German equivalent of "I am laughing" built from a participle. Where English has a three-way split, German distributes the work across three completely different solutions.
| English -ing | German solution | Example |
|---|---|---|
| Adjective/adverb ("the laughing child", "came in laughing") | Partizip I (+ endings or bare) | das lachende Kind / lachend |
| Verbal noun / gerund ("while reading") | Nominalized infinitive (often beim/zum) | beim Lesen |
| Progressive ("I am reading right now") | Simple present | Ich lese gerade. |
So the English present participle splits three ways in German. For the progressive sense — the one learners most want to express — German simply uses the simple present, optionally with gerade ("right now") to stress that the action is in progress.
Ich lese gerade ein gutes Buch.
I'm reading a good book right now. — simple present, NOT a participle.
Was machst du? — Ich koche gerade.
What are you doing? — I'm cooking. (informal) — present tense covers the progressive.
For the verbal-noun sense ("while reading," "the reading of the will"), German uses a nominalized infinitive — a capitalized neuter noun — often after beim or zum: beim Lesen ("while reading"), das Lesen ("(the) reading").
Beim Kochen höre ich gern Musik.
I like listening to music while cooking. — beim + nominalized infinitive, not a participle.
How English shapes the errors
The error is almost always the same: an English speaker treats -end as a verb ending and builds a fake progressive, Ich bin lachend for "I am laughing." This is ungrammatical. Lachend can only describe a noun or modify a verb; it cannot be the predicate of sein in that sense. (Ich bin lachend would at best read as a strange, frozen adjectival state.)
Common Mistakes
❌ Ich bin lachend.
Incorrect — Partizip I is not a verb form; you cannot build a progressive with it.
✅ Ich lache.
I'm laughing. / I laugh. — simple present covers both.
❌ Ich bin gerade ein Buch lesend.
Incorrect — no continuous tense exists in German.
✅ Ich lese gerade ein Buch.
I'm reading a book right now.
❌ Das lachend Kind.
Incorrect — when attributive, Partizip I must take an adjective ending.
✅ Das lachende Kind.
The laughing child.
❌ Beim lesend höre ich Musik.
Incorrect — for 'while reading' use the nominalized infinitive, not Partizip I.
✅ Beim Lesen höre ich Musik.
I listen to music while reading.
Key Takeaways
- Form Partizip I by adding -d to the infinitive: lachen → lachend.
- It works only as an attributive adjective (das lachende Kind, with endings) or an adverb of manner (kam lachend herein, no endings).
- Zu
- Partizip I builds the gerundive (die zu lösende Aufgabe) in formal register.
- It is never a tense: the English -ing splits in German across Partizip I (adjective/adverb), the nominalized infinitive (beim Lesen), and the simple present (for the progressive).
