Indicative

Present (Präsens) Irregular

Präsens is the default present for facts, habits, and near-future plans. German has no continuous aspect in the same way as English, so a single form often covers both “I work” and “I am working” when you add a time adverb or context.

Ich arbeite heute im Homeoffice.

Simple past (Präteritum) Irregular

Präteritum is a narrative past, common in print and in northern speech, while southern speakers lean on the perfect in conversation. sein and haben keep their Präteritum even when you otherwise avoid the preterite.

Er war müde, aber er hatte keinen Kaffee mehr.

Present perfect (Perfekt) Irregular

The Perfekt is the everyday past for finished events: auxiliary haben or sein plus participle, with sein for most motion, coming/going, and some change-of-state verbs.

Wir sind rechtzeitig angekommen und haben gefeiert.

Pluperfect (Plusquamperfekt) Irregular

The Plusquamperfekt is the pluperfect: it marks what had already completed before a later past episode in the same narrative.

Sie war schon gegangen, bevor er ankam.

er/sie/eswar gewesenhe/she/it had been

Future I (Futur I) Irregular

Futur I is for predictions, firm promises, and also probability about the present in colloquial German. Everyday speech very often uses Präsens plus a time expression instead.

Morgen schneit es, sagt der Wetterbericht.

PronounGermanEnglish
ichwerde seinI will be
duwirst seinyou will be
er/sie/eswird seinhe/she/it will be

Future II (Futur II) Irregular

Futur II (werden + participle + haben/sein) names an action that will be completed before a later time, and can also express a guess that something must already have happened.

Bis Freitag werde ich alles gepackt haben.

PronounGermanEnglish
ichwerde gewesen seinI will have been

Subjunctive

Subjunctive II (Konjunktiv II) Irregular

Konjunktiv II is the mood for politeness, contrary-to-fact if-clauses, and reported views. In speech, würde + infinitive often stands in for rarer preterit-based forms.

Könnten Sie mir bitte helfen?

PronounGerman
ichwäre
duwärest
er/sie/eswäre
wirwären
ihrwäret
sie/Siewären

Other forms

Imperative (Imperativ) Irregular

The imperative uses the du, ihr, and Sie forms of command; the informal du form drops the -st of the present for many strong verbs, and separable-prefix verbs place the prefix at the end.

Mach bitte schnell, der Zug fährt gleich ab.

PronounGerman
dusei
ihrseit
