German verb conjugation in every tense
This German verb conjugator shows the full conjugation of a verb at once: Präsens, Präteritum, Perfekt, Plusquamperfekt, Futur I and II in the Indikativ; Konjunktiv I (Präsens, Perfekt, Futur); Konjunktiv II (Präteritum, Plusquamperfekt and the würde form); the Imperativ; Partizip I and II and the zu-Infinitiv. It opens with sein: ich bin, du bist, er ist, wir sind, ihr seid, sie sind.
German verb conjugation depends on the verb type, and the tool handles each: weak verbs (machen – machte – gemacht), strong verbs with vowel changes (fahren – fährt – fuhr – gefahren), mixed verbs (bringen – brachte – gebracht), modal verbs (können – kann), separable verbs (anrufen – ich rufe an – angerufen), inseparable verbs (verstehen – verstanden), reflexive verbs (sich freuen) and the choice of haben or sein in the Perfekt.

How the conjugator works and its limits
- Weak verbs are conjugated by rule. Strong, mixed and modal verbs come from a table of about 150 verbs with their principal parts; prefixed verbs inherit from their base verb (verstehen from stehen, ankommen from kommen). Every simple-tense form for 55 common verbs (1,467 forms) was cross-checked against Wiktionary conjugation tables on 23 October 2026.
- A prefix is split off only when the rest is a known verb, so antworten stays whole. Prefixes that can be either (um-, durch-, über-, unter-) follow the most common use; check verbs such as umfahren or übersetzen, whose meaning changes with the stress.
- A strong verb missing from the table is conjugated as weak and marked with a note. Konjunktiv II of strong verbs uses the classic forms (führe, nähme); in speech most people use the würde form, shown as its own card.

German Verb Conjugator FAQ
How do you conjugate a German verb?
Take the stem (machen → mach-) and add the ending: ich mache, du machst, er macht, wir machen, ihr macht, sie machen. Strong verbs also change their vowel in some forms; type the verb here to see them all.
When is the Perfekt formed with sein?
With verbs of movement from place to place (gehen, fahren, fliegen), change of state (aufwachen, einschlafen, sterben, werden) and with sein and bleiben. Most other verbs, including all reflexive verbs, use haben.
What is the difference between Konjunktiv I and II?
Konjunktiv I (er sei, er habe) is mainly used for reported speech in writing. Konjunktiv II (er wäre, er hätte, er würde gehen) expresses wishes, hypotheses and politeness.
How do separable verbs work?
In a main clause the prefix goes to the end (Ich rufe dich morgen an), in the Partizip II ge- goes between prefix and verb (angerufen), and zu does too (anzurufen).
Does it conjugate reflexive verbs?
Yes. Type sich before the verb (sich freuen) and the reflexive pronoun appears in every form: ich freue mich, freu dich!
