> 2. What is the origin of the Sanskrit 3rd person passive aorist,
formed of the "strengthened" root (full grade of *e plus resonant plus
obstruent, lengthened grade of *e plus single consonant) plus -i, with
prefixed augment (e.g. abodhi)? It is unusual that it only occurs in
the 3rd person singular.
If *-i is identical to the *-i of the primary endings, and if I'm
right that that ending is not a "hic-et-nunc-particle" but only a
locative suffix (and therefore the secondary endings are nominal),
then (a-)bhodh-, ie the stem in o-grade, is a noun too and can be used
eg. as a base for the iterative-causative.
