Dear members,

. . .. Thus a serious Sanskrit grammar ought to use the Paninian notions, like Pr Filliozat’s « Grammaire Sanskrite Pâninéenne ».

What resources are there for an english speaker to learn Paninian grammar and how to use it.
 I'm aware of works on  Pāniṇian grammar  in english:
1) The Laghukaumudī of Varadarāja translated by James Ballantyne written in 1849
2) The Siddhānta-kaumudī translated by Chandra Vasu over 2300 pages.
3)  Pāniṇi, His Work and Its Traditions, vol. 1 background and introduction by George Cardona

Thanks,
Harry Spier
