Tun - Subjunctive I - Konjunktiv I

The subjunctive is a mood, not a tense. The Subjunctive I (Konjunktiv I) is based on the infinitive form of the verb. It is most often used to express indirect quotation (indirekte Rede). Rare in conversational use, the Subjunctive I is often seen in newspapers, usually in the third person (er tue, he is said to do).




ich tue (würde tun)*

I do

du tuest

you do

er tue
sie tue
es tue

he does
she does
it does

Because the Subjunctive I (Konjunktiv I) of "tun" in the first person (ich) is identical to the indicative (normal) form, the Subjunctive II is sometimes substituted.

wir tuen

we do

ihr tuet

you (guys) do

sie tuen

they do
Sie tuen

you do

Tun Subjunctive II - Konjunktiv II

The Subjunctive II (Konjunktiv II) expresses wishful thinking, contrary-to-reality situations and is used to express politeness. The Subjunctive II is based on the simple past tense (Imperfekttat), adding an umlaut: täte.

Deutsch English

ich täte

I would do

du tätest

you would do

er täte
sie täte
es täte

he would do
she would do
it would do


wir täten

we would do

ihr tätet

you (guys) would do

sie täten

they would do

Sie täten

you would do

Since the Subjunctive is a mood and not a tense, it can be used in various tenses. Below are examples that illustrate how tun forms the subjunctive in past or future time. In such cases, the subjunctive forms of haben or werden are combined with tun.

Past Time

Deutsch English
er habe getan

he is said to have done

ich hätte getan

I would have done

sie hätten getan

they would have done

Future Time


er werde getan haben

he will have done

ich würde tun

I would do

du würdest getan haben

you would have done
