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.

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.

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.

PronounGerman
ichtäte
dutätest

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.
