Comparative adjectives are used to compare two things or people to each other.

  • A bus is bigger than a car.
  • Bill is older than Harry.

Superlative adjectives are used to compare one member of a group to the whole group.

  • The Nile is the longest river in the world.
  • In our class Maria is the oldest and Charlie is the youngest.
