The right answer is Swiss, because it is not actually a language. Three of the national languages in Switzerland are Romance languages: French (spoken by 22.9% of the population in 2016), Italian (8.2%) and Romansh (0.5%). The fourth is German, which is a West Germanic language.

The Romance languages are the modern languages that evolved from Vulgar Latin between the third and eighth centuries. They are a subgroup of the Italic languages in the Indo-European language family.

Because of the difficulty of imposing boundaries on a continuum, various counts of the modern Romance languages are given; for example, Dalby lists 23 based on mutual intelligibility. The following, more extensive list, includes 35 current, living languages, and one extinct language, Dalmatian:

Ibero-Romance: Portuguese, Galician, Mirandese, Asturian, Leonese, Spanish, Aragonese, Ladino (Judaeo-Spanish);

Occitano-Romance: Catalan/Valencian, Occitan (lenga d'oc), Gascon;

Gallo-Romance: French/Oïl languages, Franco-Provençal (Arpitan);

Rhaeto-Romance: Romansh, Ladin, Friulian;

Gallo-Italic: Piedmontese, Ligurian, Lombard, Emilian-Romagnol;

Italo-Dalmatian: Italian, Tuscan, Romanesco, Corsican, Sassarese, Sicilian, Neapolitan, Dalmatian (extinct in 1898), Venetian (classification disputed), Istriot;

Sardinian;

Eastern Romance: Romanian (standard known as Daco-Romanian), Istro-Romanian, Aromanian, Megleno-Romanian.
