Common Irregular Partizip II Forms

1.Irregular Partizip II

With regular verbs, the Partizip II is usually predictable: machen → gemacht, lernen → gelernt. With many common verbs, however, the stem changes: gehen → gegangen, sehen → gesehen, trinken → getrunken.

With irregular verbs, it is usually best to learn the Partizip II together with the infinitive.

2.Why these forms matter

The Partizip II is used especially in the Perfekt. At A1, many very common verbs already appear with irregular forms:

To understand and build sentences like these, you need to recognize forms such as gelesen, gegangen, and getrunken. This page focuses on the forms themselves; the choice between haben and sein is a separate topic.

3.Core model

Many irregular verbs follow this broad Partizip II pattern: ge- + changed stem + -en.

This is a useful orientation, but it is not a fully mechanical rule. You cannot reliably calculate every stem change from the infinitive alone.

4.What does “irregular” mean here?

A verb is irregular here when its Partizip II is not formed simply with the normal pattern ge- + stem + -t.

With irregular verbs, especially the vowel in the stem may change: finden → gefunden (i → u), sprechen → gesprochen (e → o).

5.Common pattern: ge- … -en

Many strong verbs have these features in the Partizip II: often ge- at the beginning, a changed or partly changed stem, and often the ending -en.

Not every irregular form looks dramatically different. sehen → gesehen and geben → gegeben are still not normal -t forms.

6.Very common A1 forms

The following forms occur especially often in everyday German and simple Perfekt sentences.

It is useful to learn these verbs as pairs: gehen — gegangen, lesen — gelesen, trinken — getrunken.

7.Group 1: movement and change of place

Several very common movement verbs are irregular: gehen → gegangen, kommen → gekommen, fahren → gefahren, bleiben → geblieben.

Here the focus is only on the Partizip II forms. The fact that these verbs often use sein in the Perfekt belongs to the topic of choosing the auxiliary.

8.Group 2: seeing, reading and speaking

Many common verbs for perception and communication also have irregular forms: sehen → gesehen, lesen → gelesen, schreiben → geschrieben, sprechen → gesprochen.

9.Group 3: eating and drinking

Two especially important everyday verbs are: essen → gegessen, trinken → getrunken.

The forms show two different kinds of change, so it is better not to derive a general vowel rule from just one example.

10.Group 4: nehmen, geben, finden, helfen

These verbs are also very frequent: nehmen → genommen, geben → gegeben, finden → gefunden, helfen → geholfen.

This group shows the pattern clearly: the ending -en often stays stable, while the stem can change in different ways.

11.Not all irregular verbs end in -en

An important second group has an irregular stem but the ending -t in the Partizip II. These are often called mixed verbs because they combine properties of regular and irregular verbs.

12.Some verbs have no ge-

Not every irregular Partizip II begins with ge-. Many verbs with inseparable prefixes such as be-, ver-, er-, or ent- do not add another ge-.

The prefix already belongs to the verb. Therefore forms like gebekommen, geverstanden, or gebegonnen are not correct.

13.Separable verbs: ge- often appears in the middle

With separable verbs, ge- normally appears between the prefix and the verb stem: aufstehen → aufgestanden, anrufen → angerufen, einkaufen → eingekauft.

For irregular verbs, these examples are especially useful: aufstehen → aufgestanden and anrufen → angerufen. The separable prefix stays at the front: auf + ge + standen, an + ge + rufen. This structure helps you recognize the form.

14.The stem vowel can change

With many strong verbs, a vowel in the stem changes: sprechen → gesprochen, finden → gefunden, trinken → getrunken, nehmen → genommen, helfen → geholfen.

But there is no single vowel rule that safely produces all these forms. A better learning model is to store the infinitive and Partizip II as one pair: sprechen — gesprochen, finden — gefunden, nehmen — genommen.

15.Similar forms as memory families

Some forms are easier to remember when similar shapes are grouped together. These groups are memory aids, not complete grammar rules.

16.Recognizing the Partizip II in the Perfekt

A Perfekt sentence normally contains a form of haben or sein plus a Partizip II.

In the first sentence, gelesen is the Partizip II; in the second, gegangen. When you see a form such as gelesen, genommen, gefunden, or gebracht, it is often the Partizip II of a verb.

17.Do not confuse the infinitive and the Partizip II

The infinitive is the dictionary form: lesen, gehen, finden. The Partizip II is a different verb form: gelesen, gegangen, gefunden.

In the first sentence, lesen is an infinitive. In the second, gelesen is a Partizip II.

18.Common mistakes

Using a regular ending with an irregular verb

Incorrect: gegeht, getrinkt, gefindet. Correct: gegangen, getrunken, gefunden.

Changing the stem but forgetting ge-

Incorrect: gangen, trunken, funden. With these simple verbs you need: gegangen, getrunken, gefunden.

Adding ge- to a verb with an inseparable prefix

Incorrect: geverstanden, gebekommen. Correct: verstanden, bekommen.

Making every irregular verb end in -en

Not every irregular verb has -en: bringen → gebracht, denken → gedacht.

19.A useful way to store the forms

At A1, a compact learning format is especially practical: gehen — gegangen, sehen — gesehen, lesen — gelesen, trinken — getrunken, bringen — gebracht.

If the verb is often used in the Perfekt, the auxiliary can later be added: gehen — ist gegangen, lesen — hat gelesen. The choice between haben and sein is a separate step, but the infinitive + Partizip II pair is already needed for the pattern haben/sein + … + Partizip II.
