The Romani in Spain, generally known by the exonym () or the endonym Calé, belong to the Iberian Cale Romani subgroup, with smaller populations in Portugal (known as ) and in Southern France. Their sense of identity and cohesion stems from their shared value system, expressed among the as the ('Gypsy laws'). Traditionally, they maintain their social circles strictly within their patrigroups, as interaction between patrigroups increases the risk of feuding, which may result in fatalities. The emergence of Pentecostalism has impacted this practice, as the lifestyle of Pentecostal gitanos involves frequent contact with gitanos from outside their own patrigroups during church services and meetings. Data on ethnicity are not collected in Spain, although the public pollster CIS estimated in 2007 that the number of gitanos present in Spain is probably around one million. Name The term gitano evolved from the word egiptano ("Egyptian"), which was the Old Spanish demonym for someone from Egipto (Egypt). "Egiptano" was the regular adjective in Old Spanish for someone from Egypt, however, in Middle and Modern Spanish the irregular adjective egipcio supplanted egiptano to mean Egyptian, probably to differentiate Egyptians proper from Gypsys. Meanwhile, the term egiptano evolved through elision into egitano and finally into gitano, losing the meaning of Egyptian and carrying with it a specific meaning of Romanis in Spain. The two peoples are now unambiguously differentiated in modern Spanish, "egipcios" for Egyptians and "gitanos" for Roma in Spain, with "egiptano" being obsolete for either. Though etymologically the term gitano originally meant "Egyptian", the use itself of the Old Spanish word meaning "Egyptian" (egiptano) to refer to Romanis in Spain developed in the same way that the English word "Gypsy" also evolved from the English adjective "Egyptian" to refer to Romanis in Britain. Some Romanis, a people originating in the northern regions of the Indian subcontinent, upon their first arrivals to Europe, either claimed to be Egyptians for a more favourable treatment by local Europeans, or were mistaken as Egyptians by local Europeans. Identity The group's identity is particularly complex in Spain for a variety of reasons which are examined below. Nevertheless, it can be safely said that both from the perspective of gitano and non-gitano (payo) Spaniards, individuals generally considered to belong to this ethnicity are those of full or near-full gitano descent and who also self-identify as such. A confusing element is the thorough hybridization of Andalusian and Roma culture
