Make grammar physical.

Put words into slots, add weil, swap word order — and watch German react. Or X-ray any sentence you write.

NominativWer? — who actsAkkusativWen/Was? — receives the actionDativWem? — receiver / beneficiary
Der Kaffee ist lecker.

WER/WAS ist lecker? → masculine: „der“ stays the same here.

Tip: switch between slots with the same noun. Masculine changes twice (den / dem), feminine only in the dative (der), neuter only in the dative (dem).
