I have come across no Russian words starting in [e-] rather than
[je-], except [eto] and recent loanwords. In PIE [H1ed-] = "eat" and
[H1esti] = "is", the [e-] pressnts in Russian as [je-]. I have a good
textbook of Old Slavonic, and it does not list [eto]. I suspect that
the [e-] in Russian [eto] arose in historic Russian times as a
prefixed inarticulate emphatic noise.
