The Russian language is highly idiomatic. The idioms, part
and parcel of the language, add immensely to its richness.
Their variety is accounted for by the historical development
of the Russian language. More often than not Russian idioms
are a stumbling block for non-Russian speakers, as they fail
to understand Russian, both written and spoken, without the
mastery of a sufficient number of idioms, especially those
which occur most frequently.
