developed varieties which seem dramatically restructured as to their grammars or to be mixtures with other languages. There are several dozens of creoles of French, Spanish, and Portuguese origin, some of them spoken as national languages and lingua franca in former European colonies. Creoles of French: Antillean (French Antilles, Saint Lucia, Dominica; majority native language) Haitian (one of Haiti's two official languages and majority native language) Louisiana (US) Mauritian (lingua franca of Mauritius) Réunion (native language of Réunion) Seychellois (Seychelles' official language) Creoles of Spanish: Chavacano (in part of Philippines) Palenquero (in part of Colombia) Creoles of Portuguese: Angolar (regional language in São Tomé and Principe) Cape Verdean (Cape Verde's national language and lingua franca; includes several distinct varieties) Daman and Diu Creole (regional language in India) Forro (regional language in São Tomé and Príncipe) Kristang (Malaysia and Singapore) Kristi (regional language in India) Macanese (Macau) Papiamento (Dutch Antilles official language, majority native language, and lingua franca) Guinea-Bissau Creole (Guinea-Bissau's national language and lingua franca) Auxiliary and constructed languages Latin and the Romance languages have also served as the inspiration and basis of numerous auxiliary and constructed languages, so-called "Neo-Romance languages". The concept was first developed in 1903 by Italian mathematician Giuseppe Peano, under the title Latino sine flexione. He wanted to create a naturalistic international language, as opposed to an autonomous constructed language like Esperanto or Volapük which were designed for maximal simplicity of lexicon and derivation of words. Peano used Latin as the base of his language because, as he described it, Latin had been the international scientific language until the end of the 18th century. Other languages developed include Idiom Neutral (1902), Interlingue-Occidental (1922), Interlingua (1951) and Lingua Franca Nova (1998). The most famous and successful of these is Interlingua. Each of these languages has attempted to varying degrees to achieve a pseudo-Latin vocabulary as common as possible to living Romance languages. Some languages have been constructed specifically for communication among speakers of Romance languages, the Pan-Romance languages. There are also languages created for artistic purposes only, such as Talossan. Because Latin is a very well attested ancient language, some amateur linguists have even constructed Romance languages that mirror real languages that developed from other ancestral languages. These include Brithenig (which mirrors Welsh), Breathanach (mirrors Irish), Wenedyk (mirrors Polish), Þrjótrunn (mirrors Icelandic), and Helvetian (mirrors German).
