Wechsel im Kontext: blank the article, make the verb decide, add the rule
The level showed the article already in the sentence ("unter dem Stuhl"),
so it was answerable by recognising "dem" — it never tested wohin/wo at
all. And the frame pool was tiny: one cat, one lamp, eight nouns.
- The article is now blanked. The only evidence is the verb and whether it
has a direct object, which is the actual skill. The solved sentence is
revealed on answer, contracted where German really contracts (ins Regal,
am Bahnhof), with a note naming the fusion.
- Frames rebuilt around what decides the case: 27 new nouns, 18 new verbs,
and every frame one-way so no verb+noun pairing licenses both readings.
- Motion verbs now appear on the DATIVE side on purpose — schwimmen im See,
tanzen in der Kueche, spielen auf der Strasse — because "is it moving?" is
the wrong test and that is the main thing learners get wrong.
- The put/be pairs are drilled properly: legen/liegen, stellen/stehen,
setzen/sitzen, plus haengen and stecken, which keep the same present tense
either way so only the direct object tells you.
- ankommen added as the lexical exception: Dativ despite obvious arrival.
- New "Wohin oder wo?" info panel: the rule, the before-and-after test, the
movement trap, the verb-pair table and the exception. Reachable from the
practice screen, from the answer feedback, and from Charts.
- Feedback now explains the specific sentence rather than restating theory.
