Mastering German irregular verbs is key to achieving fluency, as these are some of the most frequently used verbs in everyday language. Though they may seem unpredictable, irregular verbs often follow certain patterns. Learning to recognize these is a good place to start.
The term irregular applies to all German verbs that don’t follow standard conjugation rules. But within this broad category, there are important distinctions.
Strong verbs have stems that change vowels in certain tenses — for example, fahren (to go) becomes fuhr (Präteritum/past tense) and gefahren (Perfekt/past participle). In contrast, truly irregular verbs, like sein and haben, aren’t consistent and often change both their stems and endings in unexpected ways.
The good news? German has fewer irregular verbs than English. With some guidance and a bit of practice, you’ll find these patterns easier to grasp than you might think.
Many irregular verbs still stick to the general structure of verb stem + conjugated ending, though they may differ from regular verbs in how the stem changes. This irregularity typically pops up in the du and er/sie/es forms, where the stem undergoes a vowel shift known as Ablaut. For example:
Some verbs go beyond the Ablaut and show irregularities not only in the stem, but also in their endings. Such verbs are considered truly irregular and they include essential ones such as:
Frustrated yet? It’s worth noting that the irregularities in German verbs aren’t simply random. They have historical roots that go back to earlier stages in the development of Germanic languages. The vowel changes we see (and struggle with) today are the result of systematic sound shifts that occurred centuries ago. Knowing this background isn’t strictly necessary, but it can help you see irregular verbs as part of a deeper structure rather than as agents of chaos.
As you’ve probably noticed, most so-called “irregular” verbs are actually strong verbs that follow recognizable patterns. The Ablaut occurs here in a systematic and predictable way — mainly in the second-person singular (du) and third-person singular (er/sie/es) forms of the present tense, as well as in the past tense and participles. While you’ll still need to memorize these verbs individually, understanding how and where these irregularities occur will help you recognize patterns and conjugate verbs in German more easily.
All in all, there are five main patterns of German strong verbs, each defined by a specific sequence of vowel changes across tenses.
In these verbs, the stem changes from e to i in the second- and third-person singular:
The stem vowel e of these verbs becomes ie in singular forms:
Here, a takes an umlaut and becomes ä:
These changes occur primarily in the simple past and past participle:
Some of the verbs in this group follow a full three-step pattern, e.g., beginnen (to begin) → begann → begonnen.
These verbs don’t fit neatly into any Ablaut pattern and must be memorized:
The following table contains a list of German irregular verbs conjugated in the present tense, with the Ablaut in bold if present. These verbs are incredibly important to know, since you’ll encounter them often in daily interactions.

| beginnen (to begin) | beginne | beginnst | beginnt | beginnen | beginnt | beginnen |
| bitten (to ask) | bitte | bittest | bittet | bitten | bittet | bitten |

Learning German irregular verbs can be easier than expected if you know the right strategies.
We’ve already covered the first and most important one: recognizing common stems and endings. Most irregular verbs use the standard endings in the present tense. But a small group of highly irregular verbs — like sein, haben and werden — have different or shortened endings that you’ll need to memorize separately. Once you’ve set those aside, you can focus on the stems of the remaining strong verbs and start learning the five main Ablaut patterns.
Another helpful tip concerns so-called “mixed” verbs. These verbs can be tricky because they look like regular verbs in the present tense, but their stems are irregular in the simple past and past participle. It’s best to learn them as a group, focusing on their past forms and using tools like flashcards or tables, such as the one below:
| Verb | Simple past | Participle |
| denken (to think) | dachte | gedacht |
| bringen (to bring) | brachte | gebracht |
| kennen (to know, e.g., a person) | kannte | gekannt |
| nennen (to name, to call) | nannte | genannt |
| rennen (to run) | rannte | gerannt |
Regardless of which kind of irregular verb you’re dealing with, a fun and effective way to learn them is by listening to and singing along with songs, such as those by Lern DEUTSCH durch SONGS. Apps and online tools such as the German Verb Conjugator can also help you practice basic German verbs and conjugation.
Of course, nothing beats practicing with native-level teachers, like those from Lingoda. Already in our German A1 course, you’ll start learning the most common irregular verbs.
English and German are both Germanic languages, so they share similarities in verbs and verb behavior. If a verb is strong in English, it tends to be strong in German, too. In many cases, even the vowel changes adhere to comparable patterns. For example:
| English | German |
| sing, sang, sung | singen, sang, gesungen |
| drink, drank, drunk | trinken, trank, getrunken |
| begin, began, begun | beginnen, begann, begonnen |
German actually has fewer irregular verbs than English — around 200, compared to nearly 300 in English. And most German irregular verbs conform to clear, consistent patterns. In contrast, many English irregular verbs have completely unpredictable past forms that you simply have to memorize.
Naturally, German has its challenges, too. Pronunciation and spelling changes can be a bit confusing at first, especially when strong verbs change their vowel in the present tense (e.g., fahren → fährst). Plus, there are more verb forms to learn; German draws a clearer distinction between the simple past (ich ging) and the perfect tense (ich bin gegangen) than English does.
In short, German irregular verbs are far more regular than they seem. With time, practice and a bit of pattern-spotting, they can actually become one of the more manageable parts of your learning journey.
German has around 200 irregular verbs. That’s fewer than in many other languages, like English (which has nearly 300!).
Irregular verbs typically do not follow the regular conjugation patterns of weak verbs, which only add simple endings. They often undergo a vowel change in their stem, called Ablaut, in their present and past forms.
German irregular verbs tend to pop up quite often, so you’ll run into them early in your journey to mastering the language. Are you introducing yourself? Then you’re probably already using the irregular verb sein. Telling your doctor you have a fever? That means you’re using haben, another essential irregular verb.
Learning these verbs can seem confusing, but they’re generally easier to handle than their English counterparts. There are fewer of them, and most follow clear and predictable patterns.
