•The comparative is used in English to compare the differences between the objects that it modifies (bigger, smaller, faster, higher). It is used in sentences where we compare two names, in the following way:

•Noun + Verb + Adjective in comparative (er-more) + than + object

•Ex. My house is larger than hers.

•This box is smaller than the one I lost.

•Your dog runs faster than Jim's dog.

The rock flew higher than the roof

•The superlative is used to describe an object that is at the upper or lower end of a quality (the tallest, the smallest, the fastest, the highest). It is used in sentences in which we compare a subject with a group of objects, like here:

•Noun+ verb + the + adjective in superlative (est-most) + Object

•Ex. My house is the largest one in our neighborhood.

•This is the smallest box I've ever seen.

•Your dog ran the fastest of any dog in the race.
