How are the accusatives of PIE neuter s-stems formed? I
know (although I might be wrong) that the oblique cases are formed on the
genitive stem. What about the accusative, though? I would think it
would be formed on the nominative formed. I see a number of
possibilities. Taking *regwos, regwes- "dark place" as an
example:
*regwos, if neuter accusatives are the same as neuter nominatives, as
in Latin and German.
*regwosm, if the root of the accusative is the nominative, but an
accusative ending is added.
*regwesm, if the root of the accusative is the genitive root, with an
accusative ending.
Or something else entirely that I don't now about. I'm
still feeling my way here.
