Conjugation of German verbs
German is spoken as a first or regularly used second language by around 130 million people in Germany, Austria, Switzerland, Luxembourg, Belgium, Liechtenstein, and South Tyrol (Italy). For a short trip to these countries, it is enough to learn a few phrases from a phrase book. But if you plan to stay for contract work or long-term education, you are to study vocabulary and grammar.
Verbs are very important in German. They change in tenses, numbers and persons, they have moods and modalities, and this is the problem of mastering the language of Goethe and Schiller. Learning German grammar requires discipline and regularity of classes, suitable formats and a positive attitude.
The PROMT.One conjugator will help you to quickly memorize the correct forms of German verbs ( machen, sehen, bringen, sein, haben) in different moods, tenses, persons and numbers. View the conjugation tables of German verbs on the screen of a smartphone, tablet or computer, and soon you will get the logic of the German language rules.
How to use the German verb conjugator

The PROMT.One Conjugator will automatically detect the part of speech. For the verb, a conjugation table will open. If the word you entered matches several parts of speech (sein, arbeiten, klein, würde, weiss), the Conjugation and Declension service will show you all the options available.
German Nouns and Adjectives
German nouns are declined by cases (Nominativ, Genetiv, Dativ, Akkusativ) and numbers, which often involves changing endings. German adjectives always agree with the nouns to which they refer, they are declined in cases, genders and numbers. It can be complex for language learners to identify and memorize the type of declension: strong declension (Tisch, Wasser, Buch, Gebäude, Haus), weak (Student, Mensch, Herr, Affe, Agent), feminine (Sprache, Schwester, Arbeit, Milch, Politik) or mixed one (Glaube, Doktor, Herz).
The PROMT.One service will help you find the correct forms of nouns and adjectives as many times as you need to memorize them.
PROMT.One is a fast and helpful tool for any language learner. Check the conjugation of verbs and see the table of tenses for English, German, Russian, French, Italian, Portuguese and Spanish.
