English 6º: Comparatives and superlatives

Comparatives are used to show the difference between two objects. 
 I have two cars.  I have a little Toyota and a big Ford.  
A comparative is used to show the difference between the two. The Ford is big so we can say “the Ford is bigger than the Toyota”.  Because the Toyota is small, we can say “The Toyota is smaller than the Ford”. 

Superlatives are used to show the difference between more than two objects.  Let’s say that I have three cars.  I have a little Toyota, a medium size Jeep and a big Ford.  A superlative is used to show the differences that exist in the group. The Ford is big so we can say “the Ford is the biggest”.  Because the Toyota is small, we can say “the Toyota is the smallest”.
