What the subjunctive does

The Konjunktiv II (subjunctive II) expresses things that are not real — hypotheticals, wishes, and polite requests — much like English “would,” “could,” and “if … were.” For most verbs the everyday form is würde + infinitive: Ich würde mehr recyceln (“I would recycle more”). This parallels the English pattern closely and is safe to use almost everywhere. It is the natural way to discuss what could be done about a problem: Wir würden das Klima schützen, “We would protect** the climate.”

The one-word subjunctive of common verbs

A few high-frequency verbs form the Konjunktiv II directly, without würde, and you should use these rather than würde: sein → wäre (“would be”), haben → hätte (“would have”), and the modals können → könnte (“could”), müssen → müsste (“would have to”), wollen → wollte, sollen → sollte (“should”), mögen → möchte (“would like”). These come from the Präteritum stem plus an umlaut and -e endings. So you say Es wäre besser (“It would be better”) and Wir könnten helfen (“We could help”), not würde sein or würde können.

Conditional “if” sentences

The subjunctive shines in unreal conditionals with wenn (“if”). Both halves go subjunctive: Wenn jeder weniger Auto fahren würde, wäre die Luft sauberer (“If everyone drove less, the air would be cleaner”). Note that wenn is subordinating, so its verb goes to the end. A common pattern pairs a würde-clause with a wäre/hätte/könnte-clause. To express a wish, add doch or nur: Wenn ich nur mehr tun könnte! (“If only I could do more!”).

Worked example

Express the hypothetical “If we used more renewable energy, we would reduce emissions” in German. (“renewable energy” = erneuerbare Energie; “to reduce” = reduzieren; “emissions” = die Emissionen)

1.Set up the “wenn” clause as unreal, using würde + infinitive and verb-final order: “Wenn wir mehr erneuerbare Energie nutzen würden, …”
2.For the main (result) clause, also use the subjunctive: “würden” + infinitive works: “… würden wir die Emissionen reduzieren.”
3.Because the subordinate “wenn” clause comes first, the main clause must start with its verb (V2): “…, würden wir …”
4.Assemble both halves with the comma between them.

Answer: “Wenn wir mehr erneuerbare Energie nutzen würden, würden wir die Emissionen reduzieren.” Both clauses use the subjunctive “würde(n) + infinitive,” and the main clause begins with its verb because the “wenn” clause fills first position.

Tip

When you want to sound polite rather than hypothetical, the subjunctive softens requests: Könnten Sie…? (“Could you…?”) is gentler than Können Sie…?, and Ich hätte gern… (“I would like…”) is the courteous way to order or ask. Use wäre, hätte, könnte as your polite go-to forms.

On the exam

On the argumentative essay and speaking tasks about global issues, the subjunctive lets you propose solutions diplomatically — Man könnte…, Es wäre sinnvoll, wenn…, Wir sollten… (“One could…, It would make sense if…, We should…”). These structures signal sophistication and are worth practicing until automatic.
