the different idioms: Sursilvan, Vallader, Puter, Surmiran, and Sutsilvan. As well, the "Pledari Grond" dictionary links to several texts on the grammar of Vallader, Puter, and Rumantsch Grischun. Official status in Switzerland and language politics In Switzerland, official language use is governed by the "territorial principle": Cantonal law determines which of the four national languages enjoys official status in which part of the territory. Only the federal administration is officially quadrilingual. Romansh is an official language at the federal level, one of the three official languages of the Canton of the Grisons, and is a working language in various districts and numerous municipalities within the canton. Official status at the federal level The first Swiss constitution of 1848, as well as the subsequent revision of 1872, made no mention of Romansh, which at the time was not a working language of the Canton of the Grisons either. The federal government did finance a translation of the constitution into the two Romansh varieties Sursilvan and Vallader in 1872, noting, however, that these did not carry the force of law. Romansh became a national language of Switzerland in 1938, following a referendum. However, a distinction was introduced between "national languages" and "official languages". The status of a national language was largely symbolic, whereas only official languages were to be used in official documents, a status reserved for German, French, and Italian. The recognition of Romansh as the fourth national language is best seen within the context of the "Spiritual defence" preceding World War II, which aimed to underline the special status of Switzerland as a multinational country. Additionally, this was supposed to discredit the efforts of Italian nationalists to claim Romansh as a dialect of Italian and establish a claim to parts of the Grisons. The Romansh language movement led by the Lia Rumantscha was mostly satisfied with the status as a national but not official language. Their aims at the time were to secure a symbolic "right of residence" for Romansh, and not actual use in official documents. This status did have disadvantages however. For instance, official name registers and property titles had to be in German, French, or Italian. This meant that Romansh-speaking parents were often forced to register their children under German or Italian versions of their Romansh names. As late as 1984, the Canton of the Grisons was ordered not to make entries into its corporate registry in
