In addition, the later grammatical schools have added numerous additional Unadi-Sutras, each particular to the respective school.[2]
Numerous commentaries on the Unadi-Sutras proper are extant, including the Uṇādisūtravṛtti of Ujjvaladatta (13th century?[3]), the Uṇādivṛtti of Svetavanavasin, the Prakriyasarvasva of
