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.
Angloromani language
Up to 1547, the Romani language was an inflected language, employing two genders, plurality and case marking. Anglo-Romani is first referenced in 1566–67. Around 1873, Romani personal pronouns became inconsistently marked, according to Leland, who also notes that case distinction began fading overall, and gender marking also disappeared. Borrow notes that in 1874, some Romani speakers were still employing complete inflection, while some were adopting the English syntax with a Romani lexicon. It seems to be around 1876 that gender distinction was no longer seen; however, the continued use of Romani plural forms was noted, along with English verb conjugation. In 1923, some plural endings were still being used on nouns, but English prepositions were used instead of Romani postpositions. Current usage has lost almost all Romani morphology and instead uses English morphology with Romani lexical items.
