Possessive adjectives in Catalan grammar are very similar to English possessive adjectives in terms of their function. They are used to indicate the ownership or relationship between the noun and the possessor. In Catalan, possessive adjectives usually agree with the noun they modify in terms of gender and number. Some of the common possessive adjectives in Catalan are: “meu” (my), “teu” (your), “seu” (his, her, its, your), “nostre” (our), “vostre” (your), and “llur” (their).
