Multilingualism in the context of "Languages of Switzerland"

The European Union (EU) has 24 official languages, of which the three most natively spoken ones are German, French and Italian. Previously, English, French and German were considered "procedural" languages, but this notion was abandoned by the European Commission, whereas the European Parliament accepts all official languages as working languages. Today, English and French are used in the day-to-day workings of the institutions of the EU. Institutions have the right to define the linguistic regime of their working, but the Commission and a number of other institutions have not done so, as indicated by several judicial rulings.

The EU asserts that it is in favour of linguistic diversity. This principle is enshrined in Article 22 of the Charter of Fundamental Rights (art. 22) and in the Treaty on European Union (art. 3(3) TEU). In the EU, language policy is the responsibility of member states, and the EU does not have a common language policy; EU institutions play a supporting role in this field, based on the principle of "subsidiarity"; they promote a European dimension in the member states' language policies. The EU encourages all its citizens to be multilingual; specifically, it encourages them to be able to speak two languages in addition to their native language. Though the EU has very limited influence in this area, as the content of educational systems is the responsibility of individual member states, a number of EU funding programmes actively promote language learning and linguistic diversity.

As of 2025, Afghanistan has an estimated population of around 49.5 million people. The country is characterized by a highly diverse, multi-ethnic, and multilingual society, reflecting its historical position at the crossroads of Central, South, and Western Asia, along ancient trade and invasion routes. The four major ethnic categories in the country are Pashtun, Tajik/Farsiwan, Hazara, and Uzbek. In addition, Afghanistan has a plethora of minor ethnic categories, including Turkmen, Baloch, Aimaq, Nuristani, Arab and many others. Together they make up the contemporary Afghan people.

Approximately 43% of the population was under the age of 15, and about 74% of Afghans lived in rural areas as of 2016. The country has one of the highest fertility rates in the world outside of Africa, with the average woman giving birth to five children over her lifetime. Around 6.8% of infants die during childbirth or early infancy. According to the World Health Organization (WHO), the nation's average life expectancy was estimated at about 63 years as of 2019. The prevalence of HIV remains very low, affecting only about 0.04% of the population.

Dutch (endonym: Nederlands [ˈneːdərlɑnts] , Nederlandse taal) is a West Germanic language of the Indo-European language family, spoken by about 25 million people as a first language and 5 million as a second language and is the third most spoken Germanic language. In Europe, Dutch is the native language of most of the population of the Netherlands and Flanders (which includes 60% of the population of Belgium). Dutch was one of the official languages of South Africa until 1925, when it was replaced by Afrikaans, a separate but partially mutually intelligible daughter language of Dutch. Afrikaans, depending on the definition used, may be considered a sister language, spoken, to some degree, by at least 16 million people, mainly in South Africa and Namibia, and evolving from Cape Dutch dialects.

In South America, Dutch is the native language of the majority of the population of Suriname, and spoken as a second or third language in the multilingual Caribbean island countries of Aruba, Curaçao and Sint Maarten. All these countries have recognised Dutch as one of their official languages, and are involved in one way or another in the Dutch Language Union. The Dutch Caribbean municipalities (St. Eustatius, Saba and Bonaire) have Dutch as one of the official languages. In Asia, Dutch was used in the Dutch East Indies (now mostly Indonesia) by a limited educated elite of around 2% of the total population, including over 1 million indigenous Indonesians, until it was banned in 1957, but the ban was lifted afterwards. About a fifth of the Indonesian language can be traced to Dutch, including many loan words. Indonesia's Civil Code has not been officially translated, and the original Dutch language version dating from colonial times remains the authoritative version. Up to half a million native speakers reside in the United States, Canada and Australia combined, and historical linguistic minorities on the verge of extinction remain in parts of France and Germany.

A multinational state or a multinational union is a sovereign entity that comprises two or more nations or states. This contrasts with a nation state, where a single nation accounts for the bulk of the population. Depending on the definition of "nation" (which touches on ethnicity, language, and political identity), a multinational state is usually multicultural or multilingual, and is geographically composed of more than one country, such as the countries of the United Kingdom.

Historical multinational states that have since split into multiple states include the Ottoman Empire, British India, Qing Empire, Czechoslovakia, the Soviet Union, Yugoslavia, the United Arab Republic and Austria-Hungary (a dual monarchy of two multinational states). Some analysts have described the European Union as a multinational state or a potential one.

Language production is the production of spoken or written language. In psycholinguistics, it describes all of the stages between having a concept to express and translating that concept into linguistic forms. These stages have been described in two types of processing models: the lexical access models and the serial models. Through these models, psycholinguists can look into how speeches are produced in different ways, such as when the speaker is bilingual. Psycholinguists learn more about these models and different kinds of speech by using language production research methods that include collecting speech errors and elicited production tasks.

Cultural mosaic (French: "la mosaïque culturelle") is a metaphor for a society composed of diverse ethnic, linguistic, and cultural groups that are encouraged to maintain their unique identities while coexisting. The idea of a cultural mosaic is intended to suggest a form of multiculturalism as seen in Canada, that differs from other systems such as the melting pot, which is often used to describe nations like the United States' assimilation.

Jeju Province (Jeju and Korean: 제주도; Hanja: 濟州道; RR: Jejudo), officially Jeju Special Self-Governing Province (Jeju: 제주특벨ᄌᆞ치도; Korean: 제주특별자치도; Hanja: 濟州特別自治道; RR: Jeju Teukbyeoljachi-do), is the southernmost province of South Korea, consisting of eight inhabited and 55 uninhabited islands, including Marado, Udo, the Chuja Archipelago, and the country's largest island, Jeju Island. The province is located in the Korea Strait, with the Korean Peninsula to the northwest, Japan to the east, and China to the west. The province has two cities: the capital Jeju City, on the northern half of the island, and Seogwipo, on the southern half of the island. The island is home to the shield volcano Hallasan, the highest point in South Korea. Jeju and Korean are the official languages of the province, and the vast majority of residents are bilingual.

Jeju Island was first settled by humans 8,000 to 10,000 years ago and the Tamna Kingdom is the earliest known civilization on the island. Beginning in the 5th century AD, the kingdom would become a tributary state of various Korean Kingdoms and briefly invaded by the Mongol Empire, before being annexed into the Goryeo in 1105 and later Joseon in 1392. Joseon ruled the island brutally and multiple uprisings occurred. Jeju Island, with the rest of mainland Korea, was annexed by the Empire of Japan in 1910. Following Japan's surrender in World War II in 1945, the islands became part of South Jeolla Province in the United States Army Military Government in Korea, before becoming a separate province on August 1, 1946. On July 1, 2006, the islands were designated a Special Self-Governing Province; it is now one of three special self-governing provinces, the others being Gangwon State and Jeonbuk State.

Within the linguistic study of endangered languages, sociolinguists distinguish between different speaker types based on the type of competence they have acquired of the endangered language. Often when a community is gradually shifting away from an endangered language to a majority language, not all speakers acquire full linguistic competence; instead, speakers have varying degrees and types of competence depending on their exposure to the minority language in their upbringing. The relevance of speaker types in cases of language shift was first noted by Nancy Dorian, who coined the term semi-speaker to refer to those speakers of Sutherland Gaelic who were predominantly English-speaking and whose Gaelic competence was limited and showed considerable influence from English. Later studies added additional speaker types such as rememberers (who remember some words and phrases but have little or no grammatical competence and do not actively speak the language), and passive speakers (who have nearly full comprehension competence but do not actively speak the language). In the context of language revitalization, new speakers who have learned the endangered language as a second language are sometimes distinguished.

In contexts of language acquisition and language teaching studies, there is sometimes a distinction between native speakers and second language speakers, depending on whether the language was learned as a language of primary socialisation or after having fully acquired a first language. In contexts of multilingualism a bilingual speaker may also be described as a heritage speaker (although a heritage language actually refers to a language whose speakers have moved from the original area where the language was spoken: e.g. Welsh is a heritage language in Patagonia, but not in Wales) if they have not been as fully exposed to one of their languages, leading to a diminished degree of confidence in themselves as speakers, and sometimes also limited competence in one of their languages.
