Using irregular verbs in different tenses (AQA GCSE German): Revision Notes
Using irregular verbs in different tenses
Understanding irregular verbs is essential for mastering German grammar. Unlike regular verbs that follow predictable patterns, irregular verbs change in unexpected ways across different tenses. This makes them challenging but incredibly important to learn, as many of the most commonly used German verbs are irregular.
What makes irregular verbs special
Irregular verbs don't follow the standard conjugation patterns that regular verbs do. When you conjugate them, you'll notice changes in the vowel sounds and sometimes completely different forms. This is particularly noticeable in three key areas: the present tense third person forms, the imperfect tense, and the past participle used in perfect tenses.
Irregular verbs in the present tense
In the present tense, irregular verbs often show vowel changes in the second and third person singular forms (du and er/sie/es). These changes help distinguish them from regular verbs and create their unique sound patterns.
Let's look at an example with the verb "tragen" (to wear/carry):
| Form | Meaning | Present tense (er/sie/es) | Imperfect (er/sie/es) | Past participle |
|---|---|---|---|---|
| tragen | to wear/carry | trägt | trug | getragen |
Notice how the 'a' in "tragen" becomes 'ä' in "trägt". This vowel change is typical of many irregular verbs in the present tense.
Irregular verbs in the imperfect tense
The imperfect tense (also called the simple past) shows another area where irregular verbs behave differently. Instead of simply adding regular endings, these verbs often have completely changed stems.
Here's an example with "haben" (to have):
| Form | Meaning | Present tense (er/sie/es) | Imperfect (er/sie/es) | Past participle |
|---|---|---|---|---|
| haben | to have | hat | hatte | gehabt |
The imperfect form "hatte" doesn't simply add endings to "haben" - it uses a completely different stem. This pattern is common among irregular verbs.
Irregular verbs in the perfect tense
The perfect tense requires the past participle, which is where irregular verbs really show their uniqueness. While regular verbs typically add "ge-" at the beginning and "-t" at the end, irregular verbs often end in "-en" and may have vowel changes throughout.
Consider "lesen" (to read):
| Form | Meaning | Present tense (er/sie/es) | Imperfect (er/sie/es) | Past participle |
|---|---|---|---|---|
| lesen | to read | liest | las | gelesen |
The past participle "gelesen" follows the pattern of starting with "ge-" and ending in "-en", which is typical for many irregular verbs.
Special rules for separable and inseparable prefixes
When working with irregular verbs that have prefixes, there are important rules to remember:
- Inseparable prefixes (like ver-, be-, er-) don't add "ge-" in the past participle
- Separable prefixes behave differently and the "ge-" goes between the prefix and the stem
- Some verbs like "gewinnen" already contain "ge-" so they don't add another one
For example, a verb with the inseparable prefix "ver-" would form its past participle without adding "ge-" at the beginning.
Practice exercises
Try completing these sentences with the correct past participle:
German to English:
- Wir sind nach Wien _______ (fahren)
- Hat er das Spiel _______? (gewinnen)
English to German:
3. We have spoken about the environment _______ (sprechen)
4. I have eaten nothing _______ (vergessen)
5. My friend has given me the book _______ (geben)
Answers:
- gefahren (travelled)
- gewonnen (won)
- gesprochen (We have spoken about the environment)
- vergessen (I have forgotten nothing)
- gegeben (My friend has given me the book)
Grammar and pronunciation tips
- Listen carefully to the vowel sounds in irregular verbs - they often change between tenses
- Most irregular past participles end in "-en" rather than "-t"
- Practice the most common irregular verbs (haben, sein, gehen, kommen) until they become automatic
- Remember that the vowel changes in present tense usually affect only du and er/sie/es forms
Useful vocabulary

Remember!
- Irregular verbs change unpredictably across tenses - memorisation is key
- Present tense changes typically occur in the du and er/sie/es forms with vowel shifts
- Imperfect forms often use completely different stems from the infinitive
- Most irregular past participles end in "-en" and begin with "ge-" (unless they have inseparable prefixes)
- Verbs with inseparable prefixes like "ver-" don't add "ge-" in the past participle
