German Verb Conjugation

KENNEN: Fully Conjugated

This page is also part of Lesson 16 of German for Beginners and the German Verb Conjugator.

In the following chart you will find the conjugation of the irregular German verb kennen (to know).

German, like many other languages, has two different verbs that can correspond to the single English verb "to know." Like Spanish, Italian and French, for example, German makes a distinction between knowing or being familiar with a person or thing (kennen) AND knowing a fact (wissen).

The verb kennen is a so-called "mixed" verb. That is to say, the infinitive's stem vowel e changes to a in the past tense (kannte) and the past participle (gekannt). It is called "mixed" because this form of conjugation reflects some traits of a regular verb (e.g., normal present tense endings and a ge- past participle with a -t ending) and some traits of a strong or irregular verb (e.g., a stem-vowel change in the past and past participle).

This verb chart uses the new German spelling (die neue Rechtschreibung).
