Things to remember
Sometimes we form an adjective like this:
wind(n)—windy（adj.)
rain(n)— rainy (adj.)
But note the spelling change with:
sun(n)—sunny(adj.)
fog(n)—foggy(adj.)
A 形容词在名词前（作定语）
形容词放在名词前作定语，修饰名词，说明事物的性质或特征。如：
an old book 一本旧书 a beautiful girl 一位漂亮的女孩
a new pen 一支新笔 hot weather 炎热的天气
有些形容词由名词加-y演变而来。如：
snow (n. 雪) → snowy (adj. 下雪多的) wind (n. 风) → windy (adj. 多风的)
rain (n. 雨) → rainy (adj. 多雨的) cloud (n. 云) → cloudy (adj. 多云的)
sun (n. 太阳) → sunny (adj. 晴朗的) fog (n. 雾) → foggy (adj. 多雾的)
注意：当形容词修饰something, anything, nothing, everything等不定
代词时，要放在这些词的后面。如：
I have something important to tell you. 我有些重要的事情告诉你。
