Document 2: Catalan language: During much of its history, and especially during the Francoist dictatorship (1939–1975), the Catalan language has often been degraded as a mere dialect of Spanish. This view, based on political and ideological considerations, has no linguistic validity. Spanish and Catalan have important differences in their sound systems, lexicon, and grammatical features, placing the language in a number of respects closer to Occitan (and French).
Document 3: Dialect: In addition to having evolved, for the most part, separately from one another and with distinct individual histories, the Latin-based regional Romance languages of Italy are also better classified as separate languages rather than true "dialects" due to the often high degree in which they lack mutual intelligibility. Though mostly mutually unintelligible, the exact degree to which the regional Italian languages are mutual unintelligible varies, often correlating with geographical distance or geographical barriers between the languages, with some regional Italian languages that are closer in geographical proximity to each other or closer to each other on the dialect continuum being more or less mutually intelligible. For instance, a speaker of purely Eastern Lombard, a language in Northern Italy's Lombardy region that includes the Bergamasque dialect, would have severely limited mutual intelligibility with a purely standard Italian speaker and would be nearly completely unintelligible to a speaker of a pure Sicilian language variant. Due to Eastern Lombard's status as a Gallo-Italic language, an Eastern Lombard speaker may, in fact, have more mutual intelligibility with a Occitan, Catalan, or French speaker than a standard Italian or Sicilian language speaker. Meanwhile, a Sicilian language speaker would have an greater degree of mutual intelligibility with a speaker of the more closely related Neapolitan language, but far less mutual intelligibility with a person speaking Sicilian Gallo-Italic, a language that developed in isolated Lombard emigrant communities on the same island as the Sicilian language.
Document 4: Catalan language: The Germanic superstrate has had different outcomes in Spanish and Catalan. For example, Catalan fang "mud" and rostir "to roast", of Germanic origin, contrast with Spanish lodo and asar, of Latin origin; whereas Catalan filosa "spinning wheel" and pols "temple", of Latin origin, contrast with Spanish rueca and sien, of Germanic origin.

Document 6: Catalan language: Catalan (/ˈkætəlæn/; autonym: català [kətəˈla] or [kataˈla]) is a Romance language named for its origins in Catalonia, in what is northeastern Spain and adjoining parts of France. It is the national and only official language of Andorra, and a co-official language of the Spanish autonomous communities of Catalonia, the Balearic Islands, and Valencia (where the language is known as Valencian, and there exist regional standards). It also has semi-official status in the city of Alghero on the Italian island of Sardinia. It is also spoken with no official recognition in parts of the Spanish autonomous communities of Aragon (La Franja) and Murcia (Carche), and in the historic French region of Roussillon/Northern Catalonia, roughly equivalent to the department of Pyrénées-Orientales.

Document 14: Catalan language: Catalan dialects are relatively uniform, and are mutually intelligible. They are divided into two blocks, Eastern and Western, differing mostly in pronunciation. The terms "Catalan" and "Valencian" (respectively used in Catalonia and the Valencian Community) are two different varieties of the same language. There are two institutions regulating the two standard varieties, the Institute of Catalan Studies in Catalonia and the Valencian Academy of the Language in Valencia.
Document 15: Catalan language: Catalan shares many traits with its neighboring Romance languages. However, despite being mostly situated in the Iberian Peninsula, Catalan differs more from Iberian Romance (such as Spanish and Portuguese) in terms of vocabulary, pronunciation, and grammar than from Gallo-Romance (Occitan, French, Gallo-Italic languages, etc.). These similarities are most notable with Occitan.
