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
Romance languages have borrowed heavily, though mostly from other Romance languages. However, some, such as Spanish, Portuguese, Romanian, and French, have borrowed heavily from other language groups. Vulgar Latin borrowed first from indigenous languages of the Roman empire, and during the Germanic folk movements, from Germanic languages, especially Gothic; for Eastern Romance languages, during Bulgarian Empires, from Slavic languages, especially Bulgarian. Notable examples are *"blancus" "white", replacing native "albus" (but Romansh "alv", Dalmatian "jualb", Romanian "alb"); *"guerra" "war", replacing native "bellum"; and the words for the cardinal directions, where cognates of English "north", "south", "east" and "west" replaced the native words "septentriō", "merīdiēs" (also "noon; midday nap"; cf. Romanian "meriză"), "oriens", and "occidens". (See History of French – The Franks.) Some Celtic words were incorporated into the core vocabulary, partly for words with no Latin equivalent ("betulla" "birch", "camisia" "shirt", "cerevisia" "beer"), but in some cases replacing Latin vocabulary ("gladius" "sword", replacing "ensis"; "cambiāre" "to exchange", replacing "mūtāre" except in Romanian and Portuguese; "carrus" "cart", replacing "currus"; "pettia" "piece", largely displacing "pars" (later resurrected) and eliminating "frustum"). Many Greek loans also entered the lexicon, e.g. "spatha" "sword" (Greek: "spáthē", replacing "gladius" which shifted to "iris", cf. French "épée", Spanish "espada", Italian "spada "and Romanian "spată"); "cara" "face" (Greek: κάρα "kára", partly replacing "faciēs"); "colpe" "blow" (Greek: κόλαφος "kólaphos", replacing "ictus", cf. Spanish "golpe", French "coup"); "cata" "each" (Greek: "katá", replacing "quisque"); common suffixes *"-ijāre/-izāre" (Greek: "-izein", French "oyer/-iser", Spanish "-ear/-izar", Italian "-eggiare/-izzare", etc.), "-ista" (Greek: "-istes").
