German Verb Conjugation: When learning German, one of the trickier aspects is getting familiar with verbs that undergo vowel changes, also called Vokalwechsel. Some verbs, like schlafen (to sleep), fallen (to fall), and fahren (to drive/go), change their vowels in the present tense. This shift usually happens in the second person singular (du) and third person singular (er/sie/es) forms, where the vowel a changes to ä.
Don’t worry—it might sound complicated, but with a bit of practice, you’ll get the hang of it! In this post, we’ll cover the rules, offer examples, and provide some tips to help you with these conjugations.

What Are Verbs with Vowel Changes?
Verbs that involve a vowel shift are known as strong verbs. In our case, we’re talking about verbs where the vowel achanges to ä in the du and er/sie/es forms. Other forms like wir, ihr, and sie/Sie remain the same as the infinitive.
General Rule:
- In the present tense, verbs with a stem vowel a shift to ä in du and er/sie/es forms.
Here’s a basic outline:
