Adjectives in Catalan grammar play a crucial role in describing and providing additional information about nouns. They agree in number and gender with the noun they modify, which means they must match in masculine/feminine and singular/plural forms. Adjectives can be used both attributively, before the noun, and predicatively, after the verb.

In Catalan, adjectives have two forms: short and long. The short form is the most common and is used in most contexts. The long form is used to provide emphasis or contrast. Adjectives also have different degrees of comparison: the comparative and the superlative.

When forming the comparative, the adjective takes the suffix -er for the comparative of superiority (més alt, taller), and -or for the comparative of inferiority (menys alt, less tall). For the superlative, the suffix -est (molt alt, very tall) is added for the absolute superlative and the phonic form “més” (més alt) is used for the relative superlative.

Understanding and correctly using adjectives in Catalan grammar is essential for expressing oneself with precision and elegance.
