Comments The standard variety is a literary composite which no one speaks, based on several dialects. Pallarese and Ribogorçan dialects are less similar to standard Catalan. Benasquese and Aiguavivan people live in isolated valleys and have a distinct phonology from their neighbors. Tortosin may be closer to Valencian. Central Catalan has about 90% to 95% inherent intelligibility to speakers of Valencian (R.A. Hall, Jr., 1989). Written Catalan is closest to Barcelona speech. Central Catalan has 87% lexical similarity with Italian, 85% with Portuguese and Spanish, 76% with Rheto-Romance, 75% with Sardinian, 73% with Rumanian. Bilingualism in Spanish, French, Italian, Sard, Occitan. All domains. All ages. Official language. Dictionary. Grammar. Literacy rate in first language: 60%. Literacy rate in second language: 96%.
