Sanskrit Grammar (Vyakarana): Sandhi, Shabda and Dhatu Rupa
Vyākaraṇa in the Odisha BSE Madhyama paper rewards rule-application. You are asked to join and split words, decline nouns and pronouns, and conjugate roots in prescribed lakāras. Marks are lost when a candidate recognises a rule but applies it in the wrong environment.
Sandhi: decide first, then apply
- Savarṇa-dīrgha: like vowels combine to the long vowel: vidyā + artham → vidyārtham; dadhi + indram → dadhīndram.
- Guṇa: a/ā + i/ī → e; a/ā + u/ū → o; a/ā + ṛ → ar: upa + indra → upendra; sura + īśa → sureśa.
- Vṛddhi: a/ā + e/ai → ai; a/ā + o/au → au: eka + eka → ekaika.
- Yaṇ: i/ī + vowel → y; u/ū + vowel → v: iti + api → ityapi; madhu + ākaram → madhvākaram.
- Visarga: -aḥ before a → -o + avagraha: rāmaḥ + agacchat → rāmo 'gacchat.
Śabda-rūpa and dhātu-rūpa
Learn declension by stem class: rāma (a), muni (i), guru (u), pitṛ (ṛ), and pronouns tad/etad/asmad/yuṣmad. For verbs, fix the voice first: bhū, kṛ, as are parasmaipada; labh, sev are ātmanepada. Then match person, number, tense.
Worked example: Join rāmaḥ + agacchat. Final -aḥ is visarga; the next word begins with short a. Visarga becomes o, and the initial a is elided with avagraha: rāmo 'gacchat. If you instead wrote rāmaḥ agacchat, you have not applied sandhi at all.
Traps: a + a is savarṇa-dīrgha, not guṇa; ṛ + vowel follows special rules, not plain guṇa; and dhātu endings depend on voice-bhavati but labhate. Also learn dual endings, since they are frequent in poetry and easy to miss.
