Formation of adjectives

There are no rules to help you recognize adjectives by their forms. But many adjectives are formed from other words by adding prefixes or suffixes.

Order of adjectives

An adjective is a word that describes a noun. In the phrase red car, red is an adjective. Sometimes we use several adjectives to describe a noun. Example: a small, red, German car.
When we use more than one adjective before a noun, the adjectives need to be in a particular order.
Most native speakers simply do it naturally. If you want your English to sound more natural, you must use the adjectives in the proper order.
