Official languages of the United Nations in the context of "Russian-language"

Spanish (español) or Castilian (castellano) is a Romance language of the Indo-European language family that evolved from the Vulgar Latin spoken on the Iberian Peninsula of Europe. It originated in the Kingdom of Castile, a historical kingdom in north-central Spain. Today, it is a global language with 519 million native speakers, mainly in the Americas and Spain, and about 636 million speakers total, including second-language speakers. Spanish is the official language of 20 countries, as well as one of the six official languages of the United Nations. Spanish is the world's second-most spoken native language after Mandarin Chinese; the world's fourth-most spoken language overall after English, Mandarin Chinese, and Hindustani (Hindi-Urdu); and the world's most widely spoken Romance language. The country with the largest population of native speakers is Mexico.

Spanish is part of the Ibero-Romance language group, in which the language is also known as Castilian (castellano). The group evolved from several dialects of Vulgar Latin in Iberia after the collapse of the Western Roman Empire in the 5th century. The oldest Latin texts with traces of Spanish come from mid-northern Iberia in the 9th century, and the first systematic written use of the language happened in Toledo, a prominent city of the Kingdom of Castile, in the 13th century. Spanish colonialism in the early modern period spurred the introduction of the language to overseas locations, most notably to the Americas.

Arabic is a Central Semitic language of the Afroasiatic language family spoken primarily in the Arab world. The International Organization for Standardization (ISO) assigns language codes to 32 varieties of Arabic, including its standard form of Literary Arabic, known as Modern Standard Arabic, which is derived from Classical Arabic. This distinction exists primarily among Western linguists; Arabic speakers themselves generally do not distinguish between Modern Standard Arabic and Classical Arabic, but rather refer to both as al-ʿarabiyyatu l-fuṣḥā (اَلعَرَبِيَّةُ ٱلْفُصْحَىٰ "the eloquent Arabic") or simply al-fuṣḥā (اَلْفُصْحَىٰ).

Arabic is the third most widespread official language after English and French, one of six official languages of the United Nations, and the liturgical language of Islam. Arabic is widely taught in schools and universities around the world and is used to varying degrees in workplaces, governments and the media. During the Middle Ages, Arabic was a major vehicle of culture and learning, especially in science, mathematics and philosophy. As a result, many European languages have borrowed words from it. Arabic influence, mainly in vocabulary, is seen in European languages (mainly Spanish and to a lesser extent Portuguese, Catalan, and Sicilian) owing to the proximity of Europe and the long-lasting Arabic cultural and linguistic presence, mainly in Southern Iberia, during the Al-Andalus era. Maltese is a Semitic language developed from a dialect of Arabic and written in the Latin alphabet. The Balkan languages, including Albanian, Greek, Serbo-Croatian, and Bulgarian, have also acquired many words of Arabic origin, mainly through direct contact with Ottoman Turkish.

English is a West Germanic language that emerged in early medieval England and has since become a global lingua franca. The namesake of the language is the Angles, one of the Germanic peoples who migrated to Britain after the end of Roman rule. English is the most spoken language in the world, primarily due to the global influences of the former British Empire (succeeded by the Commonwealth of Nations) and the United States. It is the most widely learned second language in the world, with more second-language speakers than native speakers. However, English is only the third-most spoken native language, after Mandarin Chinese and Spanish.

English is either the official language, or one of the official languages, in 57 sovereign states and 30 dependent territories, making it the most geographically widespread language in the world. In the United Kingdom, the United States, Australia, and New Zealand, it is the dominant language for historical reasons without being explicitly defined by law. It is a co-official language of the United Nations, the European Union, and many other international and regional organisations. It has also become the de facto lingua franca of diplomacy, science, technology, international trade, logistics, tourism, aviation, entertainment, and the Internet. Ethnologue estimated that there were over 1.4 billion speakers worldwide as of 2021.

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 fourth most widely used language on the Internet.

The United Kingdom is a founding member of the United Nations and one of five permanent members of the UN Security Council.

As the fifth largest provider of financial contributions to the United Nations, the UK provided 5 percent of the UN budget in 2015, and 6.7 percent of the peacekeeping budget. British English is one of the six official languages of the United Nations, and the United Kingdom is home to the International Maritime Organization, whose head office is in London.

Under the Geneva Conventions, the emblems of the International Red Cross and Red Crescent Movement are to be worn by all medical and humanitarian personnel and also displayed on their vehicles and buildings while they are in an active warzone, and all military forces operating in an active warzone must not attack entities displaying these emblems. The International Red Cross and Red Crescent Movement recognizes four protection emblems, three of which are in use: the Red Cross (recognized since 1864), the Red Crescent (recognized since 1929), the Red Lion and Sun (recognized since 1929; unused since 1980), and the Red Crystal (recognized since 2005).

The Red Cross was the original protection symbol declared at the First Geneva Convention in 1864. The Red Crescent, which was first used by the Ottoman Empire in the 1870s, and the Red Lion and Sun, which had been used only in Iran between 1924 and 1980, were both formally recognized as protection symbols following a 1929 amendment to the Geneva Conventions. Controversy stemming from the movement's successive rejections of the Red Star of David, which was established in 1899 and has been used only in Israel, led to the creation of the Red Crystal as the fourth protection symbol by a vote in 2005. In 2006, the movement announced that it was officially adopting the Red Crystal as a neutral symbol and that it was also granting formal recognition to Israel's Magen David Adom alongside the Palestine Red Crescent Society.
