Russian is an East Slavic language belonging to the Balto-Slavic branch of the Indo-European language family. It is one of the four extant East Slavic languages, and is the native language of the Russians. It was the de facto and de jure official language of the former Soviet Union. Russian has remained an official language of the Russian Federation, Belarus, Kazakhstan, Kyrgyzstan, and Tajikistan, and is still commonly used as a lingua franca in Ukraine, Moldova, the Caucasus, Central Asia, and to a lesser extent in the Baltic states and Israel.
Russian has over 253 million total speakers worldwide. It is the most spoken native language in Europe, the most spoken Slavic language, and the most geographically widespread language of Eurasia. It is the world's seventh-most spoken language by number of native speakers, and the world's ninth-most spoken language by total number of speakers. Russian is one of two official languages aboard the International Space Station, one of the six official languages of the United Nations, as well as the seventh most widely used language on the Internet.
Russian is written using the Russian alphabet of the Cyrillic script; it distinguishes between consonant phonemes with palatal secondary articulation and those without—the so-called "soft" and "hard" sounds. Almost every consonant has hard-soft counterparts, and the distinction is a prominent feature of the language, which is usually shown in writing not by a change of the consonant but rather by changing the following vowel. Another important aspect is the reduction of unstressed vowels. Stress, which is often unpredictable, is not normally indicated orthographically, though an optional acute accent may be used to mark stress – such as to distinguish between homographic words (e.g. замо́к [zamók, 'lock'] and за́мок [zámok, 'castle']), or to indicate the proper pronunciation of uncommon words or proper nouns.
Russian is a typical fusional language, where single inflectional morphemes at the end of a word are used to denote multiple grammatical features. In addition to inflection for morphology Russian also actively uses prefixes and suffixes for word formation, more so than most other Slavic languages. Also, Russian uses word compounding (including open compounding) more than most other Slavic languages. For example, "railroad" in Russian is two words ("zheleznaya doroga"), whereas in Czech it is one word ("železnice").
