Weak
Verbs
Weak
(regular or schwache) verbs are predictable or regular. (There
is really nothing "weak" about them. We use the term because it
is widely accepted and used.) Different forms of weak verbs can
be made by using the infinitive stem of the verb. To form the simple
past stem, simply add -te to the infinitive stem (the equivalent
of adding -ed in English). The past participle adds a prefix
and a suffix to the infinitive stem: ge- is the prefix and
-t is the suffix.

Strong
Verbs
Many
strong verbs have a stem vowel change in
the present, simple past and even past participle. The past participle
of strong verbs has the suffix -n or -en instead of
-t. There is no rule for determining weak or strong verbs:
they must be learned like gender of nouns
and other vocabulary.

verbs are verbs that exhibit characteristics of weak verbs and characteristics
of strong verbs. They usually have a stem vowel change but retain

in the past participle. Below are a couple common examples:

Separable
Prefix Verbs
In
English we have something similar to German separable verbs. For
instance, we can use the verb "clean up" in two ways: Clean your
room up!/Clean up your room. German would only use it the first
way. When speaking, the prefix of separable verbs is stressed whereas
the prefix of inseparable verbs is not stressed. The verb retains
its original classification as regular or irregular when prefixes
are added. And the ge- prefix in the past participle goes
between the separable prefix and the verb.
