terminology of the term "shuttle".

Since currently, there is only one space vehicle that qualifies as a
shuttle, and it happens to be called "Shuttle", when one mentions
replacement for the shuttle, it can only mean a replacement for the NASA
operated STS system, commonly known as the Shuttle, that vehicle with
cargo doors on top, delta wings , which departs vertically attached to
some big tank and two glorified dynamite sticks and lands as a plane on
a runway.

How do you qualify the russian Buran spacecraft (even though it is out of
service)?
