Siddhanta Kaumudi is a celebrated Sanskrit commentary by Bhattoji Dikshita (early 17th century) on the Ashtadhydyi and is believed to be more popular than Panini’s work. It re-arranges the sutras of Panini under appropriate heads and offers exposition that is orderly and easy to follow.
The sutras are arranged in two parts – the first part deals with the rules of interpretation, sandhis, declensions, formation of feminines, case endings, compounds, secondary derivations and the second part with conjugation, primary suffixes, Vedic grammar and accents.
English commentary of Siddhanta Kaumudi by Saradaranjan Ray & Kumudranjan Ray is highly useful to students of Sanskrit grammar who are not capable of studying the Ashtadhyayi or Siddhanta Kaumudi with the help of Sanskrit commentaries.
