. . . this use of Avagraha and this meaning of Avagraha is unknown to old grammars, Prātiśākhyas and Śikṣās.
Is the use of avagraha to mark the elision of a after e or o mentioned in any Indian premodern grammar . If not, then from where did printed editions and western grammars pick up this practice.
Thanks,
