Weak vs Strong Verbs in German: 5 Clear Rules with Examples

2026-09-17

Weak vs strong verbs in German are distinguished by how they form their past tense and past participle: weak verbs add a regular -te/-t ending, strong verbs change the stem vowel. In this article you’ll get five easy rules, 30 clear examples, and a quick practice routine you can start now.

What makes a verb weak or strong in German?

German verbs belong to two main groups. Weak verbs (regular verbs) form the Präteritum by adding -te and the Partizip II by adding -t to the stem. Strong verbs (irregular verbs) use a vowel change (Ablaut) in the past tense and often a different ending for the participle.

Key differences:

Weak: stem stays the same, only a suffix is added. Example: machen (to do) → machte (did) – made.
Strong: stem vowel changes, sometimes a prefix is added. Example: sehen (to see) → sah (saw) – saw.
Strong verbs often have a separate Partizip II that does not end in -t. Example: gehen (to go) → ging (went) – went; Partizip II gegangen (gone).

How can I identify strong verbs quickly?

There are three shortcuts learners use:

Look for a vowel change in the simple past. If the vowel shifts (e.g., a → ä, e → i, o → u), the verb is likely strong.
Check the participle. If it ends in -en and does not simply add -t, it is strong.
Memorise common patterns. Many strong verbs belong to families (e.g., fahren → fuhr, fährt, gefahren).

Example list:

fahren (to drive) – fuhr (drove) – gefahren (driven)
nehmen (to take) – nahm (took) – genommen (taken)
schreiben (to write) – schrieb (wrote) – geschrieben (written)
finden (to find) – fand (found) – gefunden (found)
laufen (to run) – lief (ran) – gelaufen (run)

When you spot these patterns, you can instantly decide whether a verb is strong.

FAQ

Are weak verbs always easier to learn than strong verbs?

Generally yes, because they follow a single regular pattern. Strong verbs require memorising individual vowel changes, but many follow common families that make them easier to group.

Can a verb be both weak and strong depending on the meaning?

Some verbs have both a weak and a strong form with slightly different meanings (e.g., brennen – weak brennte for “to burn” in a technical sense, strong brennte for “to set fire”). Context decides which form is appropriate.

Do all strong verbs have a separable prefix?

No. While many strong verbs are separable (e.g., aufstehen → stand auf), the strength of a verb is independent of separability. The key is the vowel change, not the prefix.

How many strong verbs are there in German?

There are several hundred commonly used strong verbs. Learning the most frequent 100 gives you coverage for everyday conversation.
