Today's Goal
By the end of today, you will be able to recognize and reverse the most common sandhi rules in the Gita, understanding how separate words merge at their boundaries.
What Is Sandhi?
Sandhi (संधि) literally means 'joining.' When Sanskrit words are placed next to each other, the sounds at word boundaries change according to precise rules. This is why Sanskrit can look like one long unbroken chain of letters. But once you know the rules, you can split the chain back into individual words. Think of it as the opposite of spelling — instead of memorizing exceptions, you learn predictable patterns.
| Devanagari | IAST | Pronunciation |
|---|---|---|
| कर्मणि + एव → कर्मण्येव | karmaṇi + eva → karmaṇyeva | i + e → ye — the short i becomes y before a vowel |
| च + अपि → चापि | ca + api → cāpi | a + a → ā — two short a's merge into one long ā |
Vowel Sandhi (अच्-संधि) — The Big Three Rules
When two vowels meet at a word boundary, they combine. These three rules cover most cases in the Gita.
| Devanagari | IAST | Pronunciation |
|---|---|---|
| अ + अ → आ | a + a → ā | Similar simple vowels merge: 'na + api → nāpi' (not even) |
| अ + इ → ए | a + i → e | a + i/ī merge into e: 'na + iti → neti' (not so) |
| अ + उ → ओ | a + u → o | a + u/ū merge into o: 'sa + uktam → soktam' (thus said) |
Vowel Sandhi — Semivowel Changes
When i, u, or ṛ appear before a different vowel, they convert to their semivowel form.
| Devanagari | IAST | Pronunciation |
|---|---|---|
| इ + अ → य | i + a → ya | i/ī before a different vowel → y: 'iti + uvāca → ityuvāca' |
| उ + अ → व | u + a → va | u/ū before a different vowel → v: 'madhu + ari → madhvari' |
Visarga Sandhi
The visarga (ḥ) at the end of a word changes based on what follows. This is extremely common — almost every verse in the Gita has visarga sandhi.
| Devanagari | IAST | Pronunciation |
|---|---|---|
| रामः + च → रामश्च | rāmaḥ + ca → rāmaśca | ḥ before c/ch → ś: visarga becomes palatal sibilant |
| देवः + तत्र → देवस्तत्र | devaḥ + tatra → devastatra | ḥ before t/th → s: visarga becomes dental sibilant |
| रामः + अपि → रामोऽपि | rāmaḥ + api → rāmo'pi | aḥ before a vowel → o (with avagraha ऽ showing the dropped a) |
The Avagraha (ऽ) — The Missing Letter Mark
When an initial 'a' is dropped in sandhi, the avagraha sign (ऽ) marks where it was. It's like an apostrophe showing something was removed.
| Devanagari | IAST | Pronunciation |
|---|---|---|
| सोऽयम् | so'yam | saḥ + ayam → so'yam — 'this (person)' |
| कोऽर्जुनः | ko'rjunaḥ | kaḥ + arjunaḥ — 'who is Arjuna?' |
Gītā Connection
Look again at BG 2.47: 'karmaṇyevādhikāraste.' This is actually four separate words merged by sandhi: karmaṇi + eva + adhikāraḥ + te. The i+e → ye rule and aḥ+te → aste rule are both at work. Sandhi is why the Gita looks like continuous text — but now you can reverse-engineer it.
Practice
Split these sandhi forms back into their original separate words.
- कर्मण्येव → कर्मणि + एव (karmaṇi + eva)
- नैव → न + एव (na + eva)
- चापि → च + अपि (ca + api)
- सोऽपि → सः + अपि (saḥ + api)
- देवस्तत्र → देवः + तत्र (devaḥ + tatra)
Identify the type of sandhi in each example: vowel sandhi or visarga sandhi?
- ित्युवाच — vowel sandhi (i + u → yu)
- रामश्च — visarga sandhi (ḥ + c → śc)
- नैतत् — vowel sandhi (na + etat: a + e → ai)
- तस्मादपि — vowel sandhi (tasmāt + api: t + a, but note consonant change too)
Recap
Sandhi is Sanskrit's system of sound-merging at word boundaries. The three main vowel sandhi rules (a+a→ā, a+i→e, a+u→o) plus semivowel changes and visarga sandhi cover most of what you'll encounter in the Gita. The avagraha (ऽ) marks a dropped initial 'a'.
Coming Tomorrow
Tomorrow you'll learn the 8 cases of Sanskrit nouns — the reason Sanskrit doesn't need fixed word order. This is the key to understanding WHO does WHAT to WHOM in any Gita verse.
