Adjectives are describing words that provide information about nouns, such as their color, size, shape, quality, or condition. There are different types of adjectives including opinion, size, age, shape, color, origin, and material/purpose adjectives. Adjectives are compared using comparative (-er) and superlative (-est) forms, or by using "more" and "most" for adjectives with two or more syllables. Comparative adjectives are used to show a difference or lack of difference between two people or things.

For example: silly, beautiful, horrible, difficult
A size adjective, of course, tells you how big or small something is.

3. Where a number of adjectives are used together, the order depends on the function of the adjective. The usual order is:
Value/opinion, Size, Age/Temperature, Shape, Colour, Origin, Material/Purpose

4. Positive Adjectives
The positive adjective is the simple form of the adjective without expressing increase or diminution of the
original quality: big.
Comparative Adjectives (+er)
The comparative adjective is that form of the adjective which expresses increase or diminution of the quality:
bigger. Examples are older than or more expensive than or bigger than or faster than or taller than etc.
Adjectives are compared in two ways, either by adding -er to the positive to form the comparative and -est to
the positive to form the superlative. The following adjectives are exceptions to this rule ( irregular ):
1.- good becomes better or best. 2.- bad becomes worse or worst
Superlative Adjectives (+est)
The superlative adjective is that form which expresses the greatest increase or diminution of the quality:
biggest. An adjective is in the superlative form when it expresses a comparison between one and a number of
individuals taken separately; "John is the richest man in Boston."

5. An adjective is also in the positive form when it does not express comparison; as, "A rich man." Adjectives of
two or more syllables are generally compared by prefixing more and most. Example: Paris is the most romantic
city in the world.
Using the comparative of adjectives in English is quite easy once you have understood
the few simple rules that govern them.
Below you will find the rules with examples for each
condition.
