Oblique Case — When Nouns Change Form
Quick Answer: Before any postposition, nouns and adjectives shift to oblique case. Masculine -आ nouns → -ए (sing.) / -ओं (plural). Feminine nouns add -ओं in plural only. Adjectives: -आ → -ए.

The Rule
Before any postposition, nouns and adjectives shift to oblique case. Masculine -आ nouns → -ए (sing.) / -ओं (plural). Feminine nouns add -ओं in plural only. Adjectives: -आ → -ए.
Why This Matters
English nouns barely change form ('book/books'). Hindi nouns change before postpositions: लड़का (boy, direct) → लड़के को (to the boy, oblique). This case system affects masculine nouns more than feminine ones, adding an invisible layer of grammar English speakers miss.
Examples
• to the boy — "लड़के को" [लड़का → लड़के (masc. sing. oblique before को)] • in the room — "कमरे में" [कमरा → कमरे (masc. -आ → -ए oblique)] • to the girl — "लड़की को" [लड़की → लड़की (fem. sing. unchanged in oblique)] • in big rooms — "बड़े कमरों में" [बड़ा→बड़े, कमरा→कमरों (both change in oblique plural)]
Common Mistakes
❌ लड़का को दो ✅ लड़के को दो → Before postposition को, masculine -आ nouns must change to -ए: लड़का → लड़के ❌ बड़ा कमरे में ✅ बड़े कमरे में → Adjective must also be oblique: बड़ा → बड़े before a postposition
Quick Tip
Feminine singular nouns DON'T change in oblique case (मेज़ stays मेज़). Only masculine -आ nouns change (कमरा → कमरे). Feminine plurals add -ओं (मेज़ → मेज़ों).
