Overview — Was ist der Konjunktiv I?
▾The Konjunktiv I is a German verb mood used primarily for indirect speech (indirekte Rede) — reporting what someone said or claimed without personally vouching for it. It appears in news journalism, academic writing, formal prose, and legal documents. In everyday spoken German it is rare and often replaced by Konjunktiv II.
1. Indirect speech — reporting statements, thoughts, questions, commands.
2. Set phrases / wishes — Es lebe die Freiheit!, Gott sei Dank.
3. Formal instructions — recipes, manuals, mathematical statements.
Konjunktiv I vs. Konjunktiv II — contrast
| Mood | Primary use | Register | Example |
|---|---|---|---|
| Konjunktiv I | Indirect speech (reported speech) | Formal / written / journalism | Er sagt, er komme morgen. |
| Konjunktiv II | Hypothetical / unreal / conditional | Spoken & written | Er käme morgen, wenn er könnte. |
Formation — Wie bildet man den Konjunktiv I? C1
▾Konjunktiv I is formed from the infinitive stem (remove -en) plus the Konjunktiv I endings. The critical practical point: most forms are identical to the Indikativ Präsens — only the 3rd person singular is reliably distinct for most verbs. The verb sein is the main exception: all its forms are unique.
Konjunktiv I endings
| Person | Ending | Example stem: komm- |
|---|---|---|
| ich | -e | komme |
| du | -est | kommest |
| er/sie/es | -e | komme |
| wir | -en | kommen |
| ihr | -et | kommet |
| sie/Sie | -en | kommen |

Present Konjunktiv I — Reporting present / future action C1
▾Present Konjunktiv I reports what the original speaker states about present or future events. It is introduced by reporting verbs: sagen, behaupten, erklären, berichten, meinen, mitteilen, versichern etc. The tense of the reported verb reflects the original speaker's perspective, not a shifted tense as in English.
Example sentences — news / formal style
Past Konjunktiv I — haben/sein + Partizip II C1
▾There is only one past form in Konjunktiv I: haben/sein in Konjunktiv I + Partizip II. This form reports what the original speaker described as having happened — regardless of whether it was Präteritum, Perfekt, or Plusquamperfekt in the original.
Pattern: haben / sein (Konj.I) + Partizip II
| Auxiliary | Konjunktiv I form | Used with |
|---|---|---|
| habe / habest / habe… | er habe gesehen, sie habe gesagt… | transitive verbs, most verbs |
| sei / seiest / sei… | er sei gekommen, sie sei gefahren… | motion/change-of-state verbs |
Example sentences
Future Konjunktiv I — werden (Konj.I) + Infinitiv C1
▾Future meaning in indirect speech uses werden in Konjunktiv I + Infinitiv. The 3rd person singular form werde is distinct from the Indikativ wird, so it works cleanly. Other persons often need Konjunktiv II (würde) due to the fallback rule.
Er sagt, er werde kommen. — He says he will come.
Example sentences
Konjunktiv II Fallback — Wenn Konj.I = Indikativ C1C2
▾The fallback rule: whenever a Konjunktiv I form is identical to the Indikativ Präsens, it must be replaced by Konjunktiv II — otherwise the indirect speech marker is lost and the sentence becomes ambiguous.
sie gehen (Konj.I) = sie gehen (Indikativ) → use sie gingen (Konj.II Präteritum) or sie würden gehen.
Decision table — gehen, haben, sein (selected persons)
| Verb | Person | Konjunktiv I | Indikativ | = Same? | Fallback (Konj.II) |
|---|---|---|---|---|---|
| gehen | er/sie/es | gehe | geht | No | — |
| gehen | wir | gehen | gehen | Yes | gingen |
| gehen | sie (pl.) | gehen | gehen | Yes | gingen |
| haben | ich | habe | habe | Yes | hätte |
| haben | er/sie/es | habe | hat | No | — |
| haben | wir | haben | haben | Yes | hätten |
| sein | ich | sei | bin | No | — |
| sein | er/sie/es | sei | ist | No | — |
| sein | wir | seien | sind | No | — |
| können | wir | können | können | Yes | könnten |

Indirect Speech — Indirekte Rede C1
▾In indirect speech, you report what someone said using a reporting verb and Konjunktiv I. The key differences from English: (1) there is no automatic tense backshift — the tense reflects the original speaker's perspective; (2) pronouns change to reflect the new speaker; (3) no Accusative + Infinitive structure (that is Latin/English).
1. Introduce with a reporting verb: sagen, behaupten, erklären, berichten, meinen, mitteilen, versichern, fragen.
2. Change pronouns: 1st → 3rd person etc.
3. Use Konjunktiv I (or Konj.II fallback) — no tense backshift.
4. Main clause word order: Subject + Konj.I-verb (NOT verb-final like dass-clause).

Special Uses — Wünsche, Rezepte, Mathematik C2
▾Beyond indirect speech, Konjunktiv I appears in several fossilised or specialised contexts: toasts, blessings, wishes, formal instructions in recipes and manuals, and mathematical/logical definitions. These are C2-level nuances found mostly in written German.
