Strong (Vowel-Change) Past Tense
Strong verbs (stærke verber) are a group of common Danish verbs that show the past tense through a vowel shift (ablaut) and have no ending in the past tense (e.g., 'drikke' becomes 'drak').
How It Works
In Danish, verbs are categorized as either 'weak' or 'strong'. While weak verbs follow predictable patterns like -ede or -te, strong verbs are defined by two main features:
- Vowel Shift (Ablaut): The internal vowel changes to indicate the past. For example, i often changes to a (drikke → drak) or e changes to å (se → så).
- Zero Ending: In the past tense (preterite), strong verbs do not take any suffix. You simply use the changed stem (e.g., jeg sang, not jeg sangte).
Although there are only about 130-150 strong verbs, they are among the most frequently used words in Danish. Many follow historical patterns, such as the i-a-u pattern:
binde (bind) → bandt (bound) → bundet (bound).
In the past participle (used for the perfect tense), strong verbs almost always end in -et, and the vowel may change again.

The verb 'at finde' (to find) follows the i-a-u pattern, becoming 'fandt' in the past tense.

The verb 'at synge' (to sing) changes from 'y' to 'a' in the past tense 'sang'.

The verb 'at gå' (to go/walk) is a strong verb that becomes 'gik' in the past tense.
Common Mistakes
Adding a weak past tense ending (-ede or -te) to a strong verb.
Jeg findede mine nøgler.Jeg fandt mine nøgler.Learners often try to regularize strong verbs by adding endings. Strong verbs use a vowel shift and no ending instead.
Forgetting to change the vowel, leaving the verb in the present tense.
I går finder jeg en mønt.I går fandt jeg en mønt.Because there is no suffix, if you don't change the vowel, the sentence sounds like it is in the present tense.
How It Connects
Learn This First
To understand strong verbs, you first need to be familiar with how regular Danish verbs function in both the present and past tenses. Strong verbs are defined by their lack of standard past tense suffixes (-ede or -te) and their characteristic internal vowel changes, so knowing the regular patterns is essential for identifying these exceptions.
