Languages of Switzerland

The four national languages of Switzerland are German, French, Italian, and Romansh. German, French, and Italian maintain equal status as official languages at the national level within the federal administration of the Swiss Confederation, while Romansh is used in dealings with people who speak it. Latin is occasionally used in some formal contexts, particularly to denote the country ''.
In 2020, 62.3% of the population of Switzerland were native speakers of German at home; 22.8% French ; 8% Italian ; and 0.5% Romansh. The German region is roughly in the east, north, and centre; the French part in the west; and the Italian area in the south. There remains a small Romansh-speaking native population in Grisons in the east. The cantons of Fribourg, Bern, and Valais are officially bilingual; Grisons is officially trilingual.
English is widely spoken as a second language across Switzerland, and many Anglophone migrants live in Switzerland. It is often used as a lingua franca as Switzerland has four official languages. Because of this, English is often used in advertisements in Switzerland, and many businesses and companies in Switzerland, even if they only operate domestically, have names that use English words.

History

The main languages of Swiss residents from 1950 to 2015, also continuing in percentages, were as follows:

Year	German	French	Italian	Romansh	Other
2015	63.7	22.7	8.4	0.6	5.3
2000	63.7	20.4	6.5	0.5	9.0
1990	63.6	19.2	7.6	0.6	8.9
1980	65.0	18.4	9.8	0.8	6.0
1970	64.9	18.1	11.9	0.8	4.3
1960	69.4	18.9	9.5	0.9	1.4
1950	72.1	20.3	5.9	1.0	0.7

In the 2012 survey, for the first time, respondents could indicate more than one language, causing the percentages to exceed 100%.

Federal authorities

While the National Council offers simultaneous translation to and from German, French and Italian, the Council of States does not translate debates – its members are expected to understand at least German and French.
Employees of the federal government are expected to write documents in their native tongue. 77% of the original official documents were edited in German, 20% in French, and 1.98% in Italian. More than half of the Italian speakers employed by the federal government are translators.
The Federal Supreme Court publishes its decisions only in one language, usually in the language used in the earlier instance. The so-called regest – a summary of the decision – will be offered in German, French and Italian, but only in important and influential cases.

National languages and linguistic regions

German

The German-speaking part of Switzerland constitutes about 65% of Switzerland.
In seventeen of the Swiss cantons, German is the only official language.
In the cantons of Bern, Fribourg and Valais, French is co-official; in the trilingual canton of Graubünden, more than half of the population speaks German, while the rest speak Romansh or Italian. In each case, all languages are official languages of the respective canton.
While the French-speaking Swiss prefer to call themselves Romands and their part of the country is Romandy, the German-speaking Swiss used to refer to the French-speaking Swiss as "Welsche", and to their area as Welschland, which has the same etymology as the English Welsh. Research shows that individuals with a French-sounding name in the German-speaking part suffer from social discrimination.
Nevertheless, in 2017, 11.1%, or about 920,600 of the Swiss residents speak Standard German at home, but this figure likely includes numerous German immigrants.
By the Middle Ages, a marked difference had developed within the German-speaking part of Switzerland between the rural cantons and the city cantons, divided by views about trade and commerce. After the Reformation, all cantons were either Catholic or Protestant, and the denominational influences on culture added to the differences. Even today, when all cantons are somewhat denominationally mixed, the different historical denominations can be seen in the mountain villages, where Roman Catholic Central Switzerland abounds with chapels and statues of saints, and the farmhouses in the very similar landscape of the Protestant Bernese Oberland show Bible verses carved on the housefronts instead.
In addition to this more widespread notion of Swiss German dialect, there is also Walser German, another Highest Alemannic speech brought by Walser emigrants from Valais.
Because German is the dominant language in Switzerland, many Swiss people whose first languages are French, Italian, or Romansh move into the German-speaking regions. Consequently, their children, born in these predominantly German-speaking areas, usually grow up speaking German as their primary language.

French

is the French-speaking part of Switzerland. It covers the area of the cantons of Geneva, Vaud, Neuchâtel, and Jura as well as the French-speaking parts of the cantons of Bern, Valais, and Fribourg. 1.9 million people live in Romandy.
Standard Swiss French and the French of France are highly mutually intelligible, though some differences exist. For example, like most Francophone Belgians, speakers of Swiss French use septante instead of soixante-dix and nonante instead of "quatre-vingt-dix". In the cantons of Vaud, Valais and Fribourg, speakers use huitante instead of "quatre-vingts" used in most of the rest of the French-speaking world; the cantons of Geneva, Bern and Jura use "quatre-vingts". "Sou" is used throughout Romandy for a 5-centime coin, as is "tune" when referring to a 5-Swiss-franc piece. Swiss French also uses "déjeuner, dîner, souper" for breakfast, lunch and dinner instead of "petit-déjeuner, déjeuner, dîner" used in France.
Historically, the vernacular language used by inhabitants of most parts of Romandy was Franco-Provençal. Franco-Provençal is a language sometimes considered to be halfway between the langue d'oïl and Occitan. Standard French and Franco-Provençal/Arpitan, linguistically, are distinct and mutual intelligibility is limited. Increasingly, Franco-Provençal/Arpitan is used only by members of the older generations. In parts of Jura Franc-Comtois dialects are also spoken; these belong to the same Oïl bloc as Standard French.
The term Romandy does not formally exist in the political system, but is used to distinguish and unify the French-speaking population of Switzerland. The television channel Télévision Suisse Romande served the Romande community across Switzerland and worldwide through TV5Monde until it was merged with the Radio Suisse Romande and renamed RTS in 2010.

Italian

Italian Switzerland is the Italian-speaking part of Switzerland, which includes the canton of Ticino and the southern part of Grisons. Italian is also spoken in the Gondo Valley in Valais. The traditional vernacular of this region is the Lombard language, specifically its Ticinese dialect.
The linguistic region covers an area of about 3,500 km² and has a total population of around 350,000, with the number of Italophones residing in Switzerland being 545,274.
The proportion of Italian-speaking inhabitants had been decreasing since the 1970s, after reaching a high of 12% of the population during the same decade. This was entirely because of the reduced number of immigrants from Italy to Switzerland. However it has increased again during the last decade.

Romansh

is an official language in the trilingual Canton of Grisons, where the municipalities in turn are free to specify their own official languages.
Romansh has been recognized as one of four "national languages" by the Swiss Federal Constitution since 1938. It was also declared an "official language" of the Confederation in 1996, meaning that Romansh speakers may use their language for correspondence with the federal government and expect to receive a Romansh response. Although Romansh is split into several dialects, the federal and cantonal authorities use the standardized version exclusively.
Romansh speakers remain predominant in the Surselva, the Albula Region, and the Engiadina Bassa/Val Müstair Region.

English

Many Swiss find it easier to use English as a lingua franca with other Swiss people of different linguistic backgrounds. In 2022, Switzerland ranked 23rd in Europe in the English Proficiency Index of EF language school.
Swissinfo, a multilingual outlet of Swiss Radio and Television, reported in 2021 that interview subjects are often asked technical questions in English, given that interviewers are often not proficient enough to do so in the local language. The interviewees then answer in their own local language. The interviews are later translated and dubbed over at the studio. A 2003 study on the online communication behavior of Swiss medical students showed that they quickly changed to English as soon as students from other languages were involved. The main drivers behind using English were the Italian-speaking students from Ticino, as students from other parts of the country rarely understood their messages.
While university courses in science are often held in English, in 2014 the Canton of Zug introduced an English dual education course for future commerce and information technology professionals, which came at the request of multinational companies like Glencore and Roche. Before, only Geneva offered dual education in English.
A survey carried out in 2023 showed that 6.4 percent of the Swiss inhabitants mainly speak English, while 23 percent of the working population usually speak English on the job.
In advertising and sports, English slogans and labels are frequently used, as it reduces the need for regional branding. For example, Swiss railways sell tourism offers through the "RailAway" label since 1999, and many national sport federations have English names, with their German or French names almost never being used.

Other languages

;Franco-Provençal and Lombard
Besides the national languages and the many varieties of Swiss German, several regional Romance languages are spoken natively in Switzerland: Franco-Provençal and Lombard.
;Sinte
About 20,000 Romani speak Sinte, an Indic language.
;Sign languages
Five sign languages are used: Swiss-German, French, Italian, Austrian, and German.

Neo-Latin

To avoid having to translate the name of Switzerland into the four national languages, Latin is used on the coins of the Swiss franc and on Swiss stamps. The country code top-level domain for Switzerland on the internet is .ch, the abbreviation of the Latin name, Confoederatio Helvetica ; similarly, the International vehicle registration code for Swiss automobiles is "CH". The Federal Palace of Switzerland bears the inscription .
To have a unique name across the country, several Swiss foundations and associations have Latin names, such as Pro Helvetia, Pro Infirmis, Pro Juventute, Pro Natura, Pro Patria, Pro Senectute, Pro Specie Rara, Helvetia Nostra, and many more.
