Fact

Pāṇini's first rule begins with an auspicious word

वृद्धिरादैच् ।

vṛddhirādaic |

Translation

Vṛddhi is ā, ai and au.

Meaning

Pāṇini wrote about 4,000 short rules (sūtras) that generate correct Sanskrit forms. To keep them short he used a code: aic is not a word but an abbreviation (pratyāhāra) built from the list of sounds called the Śiva-sūtras, where "ai au c" is the fourth line. The whole first rule is just three words, and it already shows the system: a technical term, a sound, and a code for a group of sounds.

Pronunciation

vṛddhirādaic |

  • vṛddhir: v + vowel ṛ, then a double dh: vṛd-dhi-rā-daic.
  • aic: the diphthong ai as in "aisle", then c ("ch").
  • ṛ is a vowel, a short syllabic r (like the "ri" in "rhythm" said quickly): mṛ-tyu, not mar-tyu.
  • bh, dh, gh, jh, ḍh are voiced consonants followed by breath: dh = d + h, as in "mad-house".
