Why These Endings Work
All feminine (die) nouns stay completely unchanged in the singular across Nominative, Accusative, Dative, and Genitive.
- Feminine nouns never change their own ending in the singular across all four cases.
- Uncountable / singular-only noun in standard usage (no common plural table).
