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).

Deutsch	English
Singular
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.

Plural
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 (Imperfekt, tat), adding an umlaut: täte.

Deutsch	English
Singular
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

Plural
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.
