The forms: würde, and the verbs with their own
The special forms come from the simple past: take the past stem, add an umlaut where possible, and add -e. Hatte becomes hätte, war becomes wäre, konnte becomes könnte. For all other verbs, würde + infinitive is normal and correct.
Politeness: the everyday use
The Konjunktiv II softens a request, just as English “could you” is softer than “can you”. In shops, offices and emails, this is the expected register.
Unreal if-sentences: now and in the past
Both halves of an unreal condition use the Konjunktiv II. For the past, use hätte or wäre + participle, exactly like the perfect tense with a Konjunktiv helper. Remember the verb-at-the-end rule after wenn.
Wishes, advice and als ob
What would you do with a year off?
Two colleagues imagine a sabbatical. Konjunktiv forms are in red. Every word has its English meaning underneath.
