Catalan is a “medium-sized” Romance language spoken by over 10 million speakers, spread over four nation states: Northeastern Spain, Andorra, Southern France, and the city of L’Alguer (Alghero) in Sardinia, Italy. Catalan is divided into two primary dialectal divisions, each with further subvarieties: Western Catalan (Western Catalonia, Eastern Aragon, and Valencian Community) and Eastern Catalan (center and east of Catalonia, Balearic Islands, Rosselló, and l’Alguer). Catalan descends from Vulgar Latin. Catalan expanded during medieval times as one of the primary vernacular languages of the Kingdom of Aragon. It largely retained its role in government and society until the War of Spanish Succession in 1714, and since it has been minoritized. Catalan was finally standardized during the beginning of the 20th century, although later during the Franco dictatorship it was banned in public spaces. The situation changed with the new Spanish Constitution promulgated in 1978, when Catalan was declared co-official with Spanish in Catalonia, the Valencian Community, and the Balearic Islands. The Latin vowel system evolved in Catalan into a system of seven stressed vowels. As in most other Iberian Romance languages, there is a general process of spirantization or lenition of voiced stops. Catalan has a two-gender grammatical system and, as in other Western Romance languages, plurals end in -s; Catalan has a personal article and Balearic Catalan has a two-determiner system for common nouns. Finally, past perfective actions are indicated by a compound tense consisting of the auxiliary verb anar ‘to go’ in present tense plus the infinitive. Catalan is a minoritized language everywhere it is spoken, except in the microstate of Andorra, and it is endangered in France and l’Alguer. The revival of Catalan in the post-dictatorship era is connected with a movement called linguistic normalization. The idea of normalization refers to the aim to return Catalan to a “normal” use at an official level and everyday level as any official language.
