Explore the usage of the subjunctive mood in German language, including its various forms, such as Konjunktiv I and Konjunktiv II, and how to use them in different contexts.
German Grammar – The Subjunctive Mood (Konjunktiv)
| Aspect | Description |
|---|---|
| Name | Konjunktiv (subjunctive) |
| Purpose | Expresses unreality, indirect speech, wishes, polite requests, hypothetical situations, and unreal conditions. |
| Two forms | Konjunktiv I – mainly for reported/indirect speech. Konjunktiv II – for wishes, unreal conditions, polite requests, and many “would‑… ” constructions. |
| Relation to other moods | Distinct from Indikativ (statement of fact) and Imperativ (command). |
| Verb type | Stem (present) | Endings | Example (verb machen) |
|---|---|---|---|
| Regular (weak) | stem of present mach‑ | ‑e, ‑est, ‑e, ‑en, ‑et, ‑en | ich mache, du machest, er/sie/es mache, wir machen, ihr machet, sie machen |
| Irregular (strong) | stem of Präteritum (often with vowel change) | same endings | sein: ich sei, du seist, er sei, wir seien, ihr seiet, sie seien |
| Mixed verbs | combine stem change + weak endings | same endings | haben: ich habe, du habest, … |
Key point: If the Konjunktiv I form is identical to the indicative (e.g., ich mache), the Konjunktiv II is used instead to avoid ambiguity.
| Verb type | Formation | Example (verb machen) |
|---|---|---|
| Weak verbs | Take the Präteritum stem, add ‑e (or ‑en) as a marker. | ich machte, du machtest, … |
| Strong verbs | Use the Präteritum stem, apply the Umlaut (if possible), and add ‑e (or ‑en). | gehen → ginge, sehen → sähe, finden → fände |
| Mixed verbs | Combine a vowel change with a weak ending. | haben → hätte, sein → wäre |
| Irregular forms | Some verbs have special subjunctive forms used especially in idiomatic expressions. | kommen → käme, wissen → wüsste |
Alternative: For many strong verbs, a periphrastic construction with würde + infinitive is accepted, especially in spoken language: ich würde gehen (instead of ich ginge).
| Direct speech | Indirect speech (Konjunktiv I) |
|---|---|
| Er sagt: „Ich komme morgen.“ | Er sagt, er komme morgen. |
| Sie meint: „Wir haben das Problem gelöst.“ | Sie meint, sie haben das Problem gelöst. |
*If Konjunktiv I coincides with the indicative, switch to Konj
