Sanskrit is called "deva-vani" — the language of the devas. Every mantra of Sanatana Dharma is in Sanskrit (or its Prakrit derivatives). Its sound-structure (varnamala) is laid out in the most systematic phonetic order — by point of articulation in the mouth, from throat to lips. 49 aksharas total — 16 vowels + 25 stops + 8 semi-vowels + sibilants. Plus the 6 Vedangas (linguistic + ritual sciences).

aṃ
anusvara — m nasalised
The dot above is the anusvara — nasal m.
aḥ
visarga — slight aspirated breath ending
The two dots after are visarga — soft h-aspirate.
'
avagraha — elided initial 'a' (rare in modern script)
Used in poetry to mark where an initial 'a' has been elided after sandhi.
The most beautiful feature of Sanskrit phonology: the consonants are arranged in a precise grid by where they are pronounced in the mouth. Each row has 5 letters — unvoiced + unvoiced-aspirated + voiced + voiced-aspirated + nasal — at the same point of articulation. From velars (throat) → palatals → retroflexes → dentals → labials (lips). Every Indian language\'s alphabet inherits this Sanskrit structure.

Sandhi = "joining". When two adjacent words combine, their boundary sounds transform per phonological rules. Sanskrit has the most elaborate sandhi system of any language — Panini lists 100+ rules covering vowel-vowel, vowel-consonant, consonant-consonant + visarga-consonant joins.
| Before sandhi | After sandhi | Rule |
|---|---|---|
| tat + ca | tachcha | Word-final t + word-initial ch = chch. |
| rāma + āśīrvāda | rāmāśīrvāda | a + ā = ā (the long absorbs). |
| su + āgata | svāgata | u + ā = vā (vowel + vowel = semivowel). |
| aha + asti | ahasti | a + a = a (drops one). |
| iti + āha | ityāha | i + ā = yā (vowel + vowel = semivowel). |
| punaḥ + āgamana | punarāgamana | aḥ (visarga) + vowel = r + vowel. |
Sandhi makes Sanskrit poetry musically flowing — but also makes word-identification challenging for beginners (a single "Devarshe" might be Deva + Rishe, broken at the join). Modern Sanskrit students learn vichchheda (un-sandhi) to recover the original words.
Function — Phonetics + pronunciation. How to pronounce each Veda-mantra correctly. The science of varna (sound), svara (accent), matra (duration), bala (force), saman (uniformity), santana (continuity).
Foundational text — Paniniya-shiksha + Yajnavalkya-shiksha + Vasishtha-shiksha + many others (one per Veda-shakha).
Modern relevance — Veda-pathshalas still teach correct pronunciation. The 8 paths (krama, jata, ghana, mala, sikha, rekha, dhvaja, danda) of Vedic recitation are taught for perfection of mantra preservation.
Function — Grammar. The systematic rules of Sanskrit. Includes dhatu (verb roots), pratyaya (suffixes), sandhi (joining), samasa (compounds).
Foundational text — Panini's Ashtadhyayi (~4th C BCE) — 3,996 sutras in 8 chapters. The most concise + comprehensive grammar in any language.
Modern relevance — Modern linguistics (Chomsky generative grammar) draws inspiration from Panini. Computer scientists study Ashtadhyayi as the first formal language specification. Panini's metalanguage is recognised as superior to Backus-Naur.
Function — Etymology. The science of word-derivation. How meaning is constructed from root + suffix.
Foundational text — Yaska's Nirukta (~7th C BCE) — comments on the rare or obscure words of the Veda. Lists nighantu (Vedic glossary).
Modern relevance — Modern Sanskrit lexicography (Monier-Williams, V.S. Apte) all build on Yaska's framework.
Function — Prosody / metre. The science of poetic metres. Each Veda + Purana uses specific metres — Anushtup (8x4 = 32 syllables), Trishtup (11x4 = 44), Jagati (12x4 = 48), Gayatri (8x3 = 24), Brihati, etc.
Foundational text — Pingala's Chhandasutra (~3rd C BCE). Defined the binary code for counting metres — anticipating modern computer science by 2,000 years.
Modern relevance — Pingala's sutras include the meru-prastara (his triangular arrangement of metres) — identical to Pascal's triangle, which Pascal "discovered" in 1654.
Function — Astrology + astronomy. The science of muhurta (right time) for Vedic rituals. Calendar + ephemeris.
Foundational text — Vedanga Jyotisha (~14th C BCE) — the oldest astronomical text. Aryabhatiya (Aryabhata, 5th C) — calculates earth's circumference, motion, eclipse timings.
Modern relevance — See /wisdom/jyotisha for the deep dive. Aryabhata's calculations were used by Indian astronomers for 1500 years; only superseded by Galileo + Kepler.
Function — Ritual procedure. How to perform yajnas + grihya rites + samskaras. The "how-to" of the Veda.
Foundational text — See /wisdom/dharma-shastras (Apastamba, Bodhayana, Ashvalayana, Sankhayana, Katyayana kalpa-sutras).
Modern relevance — Every contemporary Hindu wedding + samskara still follows a specific Kalpa-sutra of the family's Veda-shakha.
