Reported speech replacements (Konjunktiv II)

When reporting what politicians claim during a campaign, we normally use indirect speech (Konjunktiv I). But there is a catch when dealing with plural pronouns.

The Replacement Rule (Ersatzform)

For the pronouns wir (we), sie (they), and Sie (formal you), the Konjunktiv I form is almost always identical to the normal present tense. For example, "they lower" is sie senken, and the reported speech form is also sie senken.

If we use the identical form, the listener might not realize we are just reporting an unverified claim. To make it obvious, German applies a replacement rule: whenever Konjunktiv I looks like the regular present tense, we substitute it with Konjunktiv II.

Using "würden" for Most Verbs

For most action verbs, if we used their one-word Konjunktiv II form, it would look exactly like the simple past tense (Präteritum). To avoid sounding like we are talking about the past, we use the helper verb würden (would) combined with the action verb's infinitive.

The candidates claimed they would lower the tax.
Die Kandidaten behaupteten, sie würden die Steuer senken.
In the campaign they said they would implement all promises.
In der Kampagne sagten sie, sie würden alle Versprechen umsetzen.

If a verb has a very distinct Konjunktiv II form that stands out from the simple past, we use that single word instead of würden. This is almost always the case for modal verbs (like müssen becoming müssten or können becoming könnten) and helper verbs (like haben becoming hätten).

They thought they would have to promote the expansion of the railway.
Sie meinten, sie müssten den Ausbau der Bahn fördern.
The experts said they would have enough money to promote the infrastructure.
Die Experten sagten, sie hätten genug Geld, um die Infrastruktur zu fördern.

A Note on Formal Speech

Occasionally, in highly formal journalism, you might see regular verbs using their one-word Konjunktiv II form (which mimics the simple past) instead of würden, provided the introductory phrase makes the indirect speech completely obvious.

The ministers explained they were investing a lot of money into the infrastructure.
Die Minister erklärten, sie investierten viel Geld in die Infrastruktur.
