Conditional Sentences: Overview

A conditional sentence sets up an if-then: a condition (the wenn-clause) and a result (the main clause that follows from it). German organises these into three types along a single axis — how likely the condition is to be true — from genuinely open possibilities, through hypotheticals about the present, to regrets about the past that can no longer be changed. This page gives you the whole map in one view, with one clean example of each type, so you can see how they relate before diving into the dedicated pages. The most important takeaway, and the one English speakers get wrong most often, is where the word würde is allowed to live.

The three types on one axis

The three conditional types differ in mood and tense, and that difference encodes how real the speaker thinks the condition is.

Read top to bottom and the condition gets less and less real: a Type 1 condition might actually come true, a Type 2 condition is imagined and false right now, and a Type 3 condition is a closed door — the chance has already passed.

Type 1 — real conditions: wenn + present

When the condition is a real, open possibility, German keeps everything in the present indicative (the normal, factual verb form). No subjunctive, no würde.

This is the everyday "if" of plans and routines, covered in full on the real conditions page. Note that German uses the present even for future conditions — wenn es regnet, not wenn es regnen wird — and that wenn covers both English "if" and "whenever."

Type 2 — unreal present: wenn + Konjunktiv II

When the condition is hypothetical — imagined, and not true at the moment of speaking — German switches both clauses into the Konjunktiv II, the subjunctive of unreality. The condition uses a synthetic Konjunktiv II form (hätte, wäre, käme, ginge, könnte); the result typically uses würde + infinitive, or its own Konjunktiv II.

The meaning: I do not have time, so this is contrary to present fact. Hätte signals "but I don't." Full treatment is on the unreal present conditions page, and the forms themselves on the Konjunktiv II overview.

Type 3 — unreal past: wenn + hätte/wäre + participle

When the condition is about the past and can no longer be changed — a regret, a missed chance — German uses the past form of the Konjunktiv II in both clauses: hätte or wäre plus the past participle (the Plusquamperfekt in the subjunctive).

The meaning: I did not have time, so I did not come — and nothing can change that now. Both clauses sit in the past subjunctive. Details on the unreal past conditions page.

Word order: the wenn-clause and the comma flip

In every type, the wenn-clause is a subordinate clause, so its finite verb goes to the very end: wenn es regnet, wenn ich Zeit hätte, wenn ich Zeit gehabt hätte. When the wenn-clause comes first (the usual order), it fills the entire first slot of the sentence (the Vorfeld). The main clause that follows must then begin with its own finite verb, right after the comma — subject and verb invert.

The same two clauses, two orders. When the condition leads, the verb of the result clause jumps in front of its subject (bleibe ich); when the result leads, everything is normal (ich bleibe) and the wenn-clause trails. This verb-before-subject flip after a fronted wenn-clause is purely the V2 rule: the subordinate clause counts as the first element, so the finite verb must come second.

The key insight: würde lives in the result, not the condition

Here is the rule that English transfer destroys, and the one this overview exists to nail down. English "would" appears in the result clause ("If I had time, I would come"). Learners then assume German würde works the same — but they wrongly copy it into the wenn-clause too, producing Wenn ich würde Zeit haben. This is wrong.

The condition uses the synthetic Konjunktiv II (hätte, wäre, käme …); würde belongs in the result clause. So "If I had time, I would come" is:

Why this division of labour? The wenn-clause already signals unreality structurally — it is the hypothesis — and German prefers the compact synthetic forms hätte, wäre, käme, ginge, wüsste, könnte there. Würde is the general-purpose substitute that steps in mainly in the result clause, where the synthetic form would sound stilted or be hard to recognise (würde kommen is far more natural than the synthetic käme for many speakers). The common verbs haben, sein, and the modals almost always use their synthetic Konjunktiv II (hätte, wäre, könnte, müsste) on both sides rather than würde. More on this division on the würde-form page.

Dropping wenn: the verb-first conditional

In all three types, wenn can be omitted, and the condition is then signalled by fronting the finite verb to first position — the verb-first conditional. This is somewhat more formal or literary and is the German equivalent of English "had I known" / "were I you."

This is covered for real conditions on the real conditions page and across all types on the mixed/wenn-less page.

Common Mistakes

Key Takeaways

• The three types run along a reality axis: real (present indicative), unreal present (Konjunktiv II), unreal past (past Konjunktiv II with hätte/wäre
  • participle).
• The wenn-clause is subordinate — verb to the end — and when it comes first, the main clause begins with its verb.
• würde belongs in the result clause, never the condition; the condition uses synthetic hätte/wäre/käme.
• For sein, haben, and modals, prefer the synthetic Konjunktiv II (wäre, hätte, könnte) on both sides over würde.
• wenn can be dropped, with the verb fronted to mark the condition (Hätte ich Zeit, …).
