@Neith recently said the following in his comment on my question about extinct phonemes:
Ivan Turgenev once called Russian language “great, mighty, truthful and free” («великий, могучий, правдивый и свободный», see turgenev.org.ru/e-book/russki_yazyk.htm), and schoolchildren are made to memorize this “prose poem”. Shortened to “great and mighty”, this idiom entered everyday Russian speech, to the point that if you hear «великий и могучий» without any noun then it’s surely means just Russian language.
Great and mighty are relative things, so I got very much curious as to what objective evidence is there to support the idea that the Russian language is greater and mightier than other languages, at least in some aspects.
My question is this: What are some examples of things present in Russian and absent in all or almost all other languages, or what are some objective parameters on which the Russian language beats all or almost all other languages?
My question is not meant to be broad, because I just want a few nice examples rather than a broad comparative analysis or a full list of all special things about Russian. An answer that provides 1-3 nice examples would be a great acceptable answer. I just want a few specific examples with which I could make other people impressed by the might of the Russian language. I want a few objective examples to which non-Russian speakers would react, "Wow!"
What I am looking for is things like:
unique grammatical constructions, like the future passive participle in Latin,
examples of frequently used words or constructions that have no equivalent in any other language, like Schadenfreude in German,
examples of how a Russian sentence can convey its idea so precisely and succinctly that it would require much more words in any other language,
data comparing Russian to other languages on any meaningful objective parameter like the number of words, number of prepositions, etc.,
and other objective(!) things that can cause a wow reaction.
The criterion is very simple: the stronger the wow effect the better. I humbly hope that this criterion is intuitively understandable to any user of this SE. Please just kindly use your common sense.
I like the Russian language and want to find some facts with which I can impress other people about Russian, and I humbly hope that native speakers can kindly help me find such facts.
