Russian prepositions v and na

[Jules Levin]

The only comment I would add to Denis Crnkovic's reference to open vs.
enclosed spaces is that v seems to be the marked member; with "v" you are
definitely inside, but with "na" you may be in or out.  Note also the
"literalness" of 'v' as opposed to the more metaphoric or abstract flavor of
'na':  v kvartire ~ na kv.  Also, whatever the historic logic, many modern
spaces probably take their preposition by analogy with already existing
usages involving analogous spaces.
