Title: German verbs
Content:  German verbs may be classified as either weak, with a dental consonant inflection, or strong, showing a vowel gradation (ablaut). Both of these are regular systems. Most verbs of both types are regular, though various subgroups and anomalies do arise; however, textbooks for learners often class all strong verbs as irregular. The only completely irregular verb in the language is sein (to be). There are more than 200 strong and irregular verbs, but just as in English, there is a gradual tendency for strong verbs to become weak.

The coherence of the strong verb system is still present in modern German, Dutch, Icelandic and Faroese. For example, in German and Dutch, strong verbs are consistently marked with a past participle in -en, while weak verbs have a past participle in -t in German and -t or -d in Dutch.

Content:  In the Germanic languages, a strong verb is a verb that marks its past tense by means of changes to the stem vowel (ablaut). The majority of the remaining verbs form the past tense by means of a dental suffix (e.g. -ed in English), and are known as weak verbs. In modern English, strong verbs include sing (present I sing, past I sang, past participle I have sung) and drive (present I drive, past I drove, past participle I have driven), as opposed to weak verbs such as open (present I open, past I opened, past participle I have opened).

The key distinction is that most strong verbs have their origin in the earliest sound system of Proto-Indo-European, whereas weak verbs use a dental ending (in English usually -ed or -t) that developed later with the branching off of the Proto-Germanic. As in English, in all Germanic languages weak verbs outnumber strong verbs.
