Languages

Switzerland has four national languages: mainly German (spoken natively by 62.8% of the population in 2016); French (22.9%) spoken natively in the west; and Italian (8.2%) spoken natively in the south. The fourth national language, Romansh (0.5%), is a Romance language spoken locally in the southeastern trilingual canton of Grisons, and is designated by Article 4 of the Federal Constitution as a national language along with German, French, and Italian. In Article 70 it is mentioned as an official language if the authorities communicate with persons who speak Romansh. However, federal laws and other official acts do not need to be decreed in Romansh.

In 2016, the languages most spoken at home among permanent residents aged 15 and older were Swiss German (59.4%), French (23.5%), Standard German (10.6%), and Italian (8.5%). Other languages spoken at home included English (5.0%), Portuguese (3.8%), Albanian (3.0%), Spanish (2.6%) and Serbian and Croatian (2.5%). 6.9% reported speaking another language at home. In 2014 almost two-thirds (64.4%) of the permanent resident population indicated speaking more than one language regularly.

The federal government is obliged to communicate in the official languages, and in the federal parliament simultaneous translation is provided from and into German, French and Italian.

Aside from the official forms of their respective languages, the four linguistic regions of Switzerland also have local dialectal forms. The role played by dialects in each linguistic region varies dramatically: in German-speaking regions, Swiss German dialects have become more prevalent since the second half of the 20th century, especially in the media, and are used as an everyday language for many, while the Swiss variety of Standard German is almost always used instead of dialect for written communication (c.f. diglossic usage of a language). Conversely, in the French-speaking regions, local Franco-Provençal dialects have almost disappeared (only 6.3% of the population of Valais, 3.9% of Fribourg, and 3.1% of Jura still spoke dialects at the end of the 20th century), while in the Italian-speaking regions, the use of Lombard dialects is mostly limited to family settings and casual conversation.

The principal official languages have terms not used outside of Switzerland, known as Helvetisms. German Helvetisms are, roughly speaking, a large group of words typical of Swiss Standard German that do not appear in Standard German, nor in other German dialects. These include terms from Switzerland's surrounding language cultures (German Billett from French), from similar terms in another language (Italian azione used not only as act but also as discount from German Aktion). Swiss French, while generally close to the French of France, also contains some Helvetisms. The most frequent characteristics of Helvetisms are in vocabulary, phrases, and pronunciation, although certain Helvetisms denote themselves as special in syntax and orthography. Duden, the comprehensive German dictionary, contains about 3000 Helvetisms. Current French dictionaries, such as the Petit Larousse, include several hundred Helvetisms; notably, Swiss French uses different terms than that of France for the numbers 70 (septante) and 90 (nonante) and often 80 (huitante) as well.

Learning one of the other national languages is compulsory for all Swiss pupils, hence many Swiss are supposed to be at least bilingual, especially those belonging to linguistic minority groups. Because the largest part of Switzerland is German-speaking, many French, Italian, and Romansh speakers migrating to the rest of Switzerland and the children of those non-German-speaking Swiss born within the rest of Switzerland speak German. While learning one of the other national languages at school is important, most Swiss learn English to communicate with Swiss speakers of other languages, as it is perceived as a neutral means of communication. English often functions as the de facto lingua franca.
