Caló (Spanish: [kaˈlo]; Catalan: [kəˈɫo]; Galician: [kaˈlɔ]; Portuguese: [kɐˈlɔ]) is a language spoken by the Spanish and Portuguese Romani. It is a mixed language (referred to as a Para-Romani language in Romani linguistics) based on Romance grammar, with an adstratum of Romani lexical items through language shift by the Romani community. It is often used as an argot, a secret language for discreet communication amongst Iberian Romani. Catalan, Galician, Portuguese, and Spanish caló are closely related varieties that share a common root.
