Russian has over 258 million total speakers worldwide.^[29] It is the most spoken native language in Europe,^[30] the most spoken Slavic language,^[31] as well as the most geographically widespread language of Eurasia.^[31] 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.^[32] Russian is one of two official languages aboard the International Space Station,^[33] one of the six official languages of the United Nations,^[34] as well as the fourth most widely used language on the Internet.^[35]

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 a hard or soft counterpart, and the distinction is a prominent feature of the language. Another important aspect is the reduction of unstressed vowels. Stress, which is often unpredictable, is not normally indicated orthographically,^[36] 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 names.
