Romani people
Most Romani speak one of several dialects of the Romani language, an Indo-Aryan language, with roots in Sanskrit. They also often speak the languages of the countries they live in. Typically, they also incorporate loanwords and calques into Romani from the languages of those countries and especially words for terms that the Romani language does not have. Most of the "Ciganos" of Portugal, the Gitanos of Spain, the Romanichal of the UK, and Scandinavian Travellers have lost their knowledge of pure Romani, and respectively speak the mixed languages Caló, Angloromany, and Scandoromani. Most of the speaker communities in these regions consist of later immigrants from eastern or central Europe.
Romance languages
The Romance languages are written with the classical Latin alphabet of 23 letters – "A", "B", "C", "D", "E", "F", "G", "H", "I", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "V", "X", "Y", "Z" – subsequently modified and augmented in various ways. In particular, the single Latin letter "V" split into "V" (consonant) and "U" (vowel), and the letter "I" split into "I" and "J". The Latin letter "K" and the new letter "W", which came to be widely used in Germanic languages, are seldom used in most Romance languages – mostly for unassimilated foreign names and words. Indeed, in Italian prose is properly . Catalan eschews importation of "foreign" letters more than most languages. Thus Wikipedia is in Catalan but in Spanish.
