There are three forms of comparison:

- positive
- comparative
- superlative


Comparative adjectives are used to compare differences between the two objects they modify (larger, smaller, faster, higher). They are used in sentences where two nouns are compared, in this pattern.

Noun (subject) + verb + comparative adjective + than + noun (object).

Superlative adjectives are used to describe an object which is at the upper or lower limit of a quality (the tallest, the smallest, the fastest, the highest). They are used in sentences where a subject is compared to a group of objects.

Noun (subject) + verb + the + superlative adjective + noun (object).


In English, you can usually add -er or -est to the end of an adjective to make it comparative or superlative. For example, “cool” can be modified to become “cooler” or “coolest.” But some adjectives are irregular and are modified differently. Here is a list of irregular adjectives in English.
