Indefinite articles in Catalan grammar are often used similarly to their counterparts in English and other Romance languages. In Catalan, the main indefinite articles are “un” (a, an, or one for masculine nouns) and “una” (a, an, or one for feminine nouns). These articles are used to express an indefinite quantity or the general idea of a noun, making them essential building blocks for learning Catalan grammar. In the exercises below, we will practice using “un” and “una” in different sentences.
