形容词是用来修饰、描绘名词的，通常在句中作定语、表语或宾补，有时还可作状语。如：
He is honest and hardworking.
I found the book interesting.
某些形容词与定冠词连用表示一类人作主语时，谓语通常用复数形式。如：
The rich and the poor live in different parts of the city.
The English like to be with their families.
多个形容词作定语修饰名词的顺序：
冠词+序数词+基数词+性质状态（描述性）+形状大小+新旧老少+颜色+国籍+材料+名词。如： the second five interesting big new red Chinese wall papers.
