Reduplication in Russian
Linguistic reduplication is a distinct grammatical feature in Russian, where it can be used to derive reduplicated forms from existing stems to intensify their meanings in different ways. Reduplication is also observable in borrowed words, such as "пинг-понг" ([pʲɪnkˈponk]; ping-pong) and "зигзаг" ([zʲɪɡˈzak]; zig-zag), but since the words were borrowed as is from other languages, they are not examples of reduplication as it works in the grammar of Russian.
