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 tuestyou 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 tuenwe do
ihr tuetyou (guys) do
sie tuenthey do
Sie tuenyou 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.
ich täteI would do
du tätestyou would do
er täte
sie täte
es täte
he would do
she would do
it would do
wir tätenwe would do
ihr tätetyou (guys) would do
sie tätenthey would do
Sie tätenyou 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
er habe getanhe is said to have done

Future Time
