Vedic accent

The pitch accent of Vedic Sanskrit, or Vedic accent for brevity, is traditionally divided by Sanskrit grammarians into three qualities, udātta उदात्त “raised” (acute accent, high pitch), anudātta अनुदात्त “not raised” (from अ(न्)- (negative prefix) + उदात्त) (unstressed, or low pitch, grave accent) and svarita स्वरित “sounded” (high falling pitch, corresponds to the Greek circumflex accent). It is most similar to the pitch-accent) system of modern-day Japanese.


  • अग्निम् ईळे पुरोहितं (classical: अग्निम् ईडे पुरोहितं)
  • “Agni I praise, the high priest.”
  • A-U-S-A-A-U-S-A (where A=anudātta, U=udātta, S=svarita),
  • _¯__¯_
  • -.–.-.x (the second half-pada is iambic)).
  • U-S-U-S-A-A-A-U
  • ¯\¯___¯

  • ’ (= “innate”) (from changes within a word, as in ’ for , as in the example above (u becomes v before a vowel)
  • ’ (= “caused by quickness”) (u becoming v or i becoming y where two words meet, as in ’ for ) (i becomes y before a vowel)
  • ’ (= “coalescence”) (vowel contraction where two words meet, as in ’ for )
  • ’ (= “close contact”) (prodelision with avagraha, where two words meet, as in ’ for ). In Vedic Sanskrit, most of the words have one accented syllable, which is traditionally called udātta (“raised”) and written with an acute mark in the transcription. The position of that accent in inherited words generally reflects the position of Proto-Indo-European accent, which means it was free and so not phonologically predictable from the shape of the word. Some words (finite verbs of main clauses, vocatives that do not occur sentence initially, and certain pronouns and particles) do not have an accented syllable, consisting entirely of unaccented syllables.

Unaccented syllables are called anudātta (“not raised”) and are not marked in the transcription. Phonetically, accented Rigvedic syllable was characterized by height (rather than prominence) as a “high tone”, immediately falling in the next syllable. The falling tone in the post-tonic syllable is called svarita (“sounded”). For example, in the first pada) of the Rigveda, the transliteration means that the eight syllables have an intonation ofor iconically, ईळे (classical: ईडे) is a finite verb and thus has no udātta, but its first syllable is svarita because the previous syllable is udātta. Vedic meter is independent of Vedic accent and exclusively determined by syllable weight, so that metrically, the pada reads as

When the Vedas were composed, svarita was not phonologically relevant. However, linguistic changes in oral transmission of the samhita before it was written down, mostly by the loss of syllabicity of high vowels when followed by a vowel, the tone has become relevant and is called an independent svarita. In transcription, it is written as a grave mark. Such svarita may follow an anudātta. For example, in RV 1.10.8c, became

Independent svarita is caused by sandhi of adjacent vowels. There are four variants of it: Independent svarita occurs about 1300 times in the Rigveda, or in about 5% of padas).


  • svarita is marked with a small upright stroke above a syllable: ◌॑ (Unicode: U+0951).
  • anudātta is marked.
  • If it is right before an udātta or an independent svarita, it is marked with a horizontal line below the syllable: ◌॒ (Unicode: U+0952).
  • If the first syllable in a pada is anudātta, that syllable and all following syllables that are anudātta are marked with the horizontal line up to but not including the first syllable not an anudātta.
  • If an independent svarita syllable is right before an udātta syllable, instead of putting the anudātta mark and the svarita mark on the same syllable, a numeral 1 (१) (if the svarita vowel is short) or a numeral 3 (३) (if the svarita vowel is long) is written between the syllables in question, and the numeral bears both the svarita mark and the anudātta mark: अ॒प्सु (apsú) + अ॒न्तः (antáḥ**) → अ॒प्स्व१॒॑न्तः (apsvà(1)ntáḥ), or क्व॑ (kvà) + इ॒दानीं॑ (idā́nīṃ**) → क्वे३॒॑दानीं॑ (kvè(3)dā́nīṃ)
  • All other syllables are unmarked. In Latin script transcription, udātta is marked with an acute accent, independent svarita is marked with a grave accent, and other syllables are unaccented, and not marked.
