Runglish

[Darya Kostina]

David,
as to s/so, v/vo, k/ko with any initial consonants, it is
now considered not subject to any reasonable consideration
but to historic conventions.
If it was not just a rhetorical question, then my guess
is:

Semantic and grammatical reasons are to be minded as well.
There are double-sound deverbals ('vvedeniye' etc.) in
which the vowel was dropped and which are probably
considered ok just because they are entities. When it
comes to prep+notional word, those two generally must not
be fused. Sometimes the preposition pre-marks the pending
case, while the inflexion alone may not be so obvious a
sign (may be the same for two cases/more). But exceptions
are numerous. Sometimes they happen for haplological
reasons (v volosakh). Euphony and the desire not to
stretch a long word even further are additional factors.
Generally, the 'o' between is likely to appear when the
word starts with CC/CCC, not with a single C.
Besides, who knows, maybe class connotations or the
quality of the initial vowel did influence.


And,
Ron's Slavicist friend is right in that [sch] is history.
What might have been 'fresh cherries' two hundred years
ago in Russia, in one of its parts or for one of its
inhabitants, now definitely is 'shshit'.
