An adjective is a word that modifies - or changes the meaning of - a noun or pronoun. This usually means expressing that a noun or pronoun has a certain quality, trait, or characteristic.

Adjectives in Latin do not have their own genders and numbers. They match the gender and number of the noun they modify (that's how you know which noun goes with which adjective.) They also match the case of the noun they modify.

• rana alba
• pirata malus

This is why it's important to know the gender of nouns.
