Having fun with adjectives!
Have a look at this mindmap. It will help you to see the different types of adjectives.
In grammar, an adjective is a word whose main function is to modify a noun or pronoun, giving more information about the noun or pronoun's referent.
Not all languages have adjectives, but most, including English, do. (English adjectives include big, old, and tired, among many others.)
