It is said of the words or locutions that belong to a foreign language, that they are not adopted even if they have become popular. By extension it is said in addition to the vulgarly deformed or poorly pronounced words, but this is more an error of interpretation by "barbarity" that in some cases is synonymous with barbarism outside of linguistics; although the RAE has already accepted it. It is a voice inherited from the Latin barbarismus, i, for barbaria, ae ("uncivilized foreign people"); which indeed comes from the Greek 946; 945; 961; 946; 945; 961; 953; 963; 956; 959; 962; (barbarismós) to pejoratively name the Persians, a socially backward (undemocratic) invading people with a language that sounded to the Hellenes like "bar bar bar. . .
