Comparisons and superlatives
You can use comparatives to compare two things or people.
"I am taller than my brother. / My sister is more intelligent than our cat"
Notice how we use 'than' when making a comparison.
You can use superlatives to talk about the difference between more than two things or people.
"My dad is the tallest in our entire family. / Dolphins are the most intelligent animals in the world"
