German: Definite articles in nominative and accusative

You are booking a train seat and the app asks whether the ticket is for the window or a window—German encodes gender and case on articles. Nominative names the subject slot; accusative often marks the direct object after many transitive verbs. So the same English "the" becomes der/die/das in nominative and shifts for masculine accusative while feminine and neuter stay stable in this beginner pattern.

Use this when building short transactional sentences and reading signs. Edge case: plural die looks like feminine singular; context and noun plural marking disambiguate. DW's open course material anchors listening and grammar together [1]; the Duden grammar portal supports precise article lookup [2].
