Adjectives are words that describe nouns. In Latin they may change their endings for a number of reasons...


Adjectives have 3 forms: Positive (ie: "big"), Comparative (ie: "bigger") and Superlative (ie: "biggest/very big"). The Latin word for an adjective changes in suit:

  • Masculine
  • Feminine
  • Neuter
