Using い and な adjectives


According to the book I am reading, "Sakura is beautiful" is written as

> さくらはきれいです

and "Sakura is a beautiful flower" is

> さくらはきれいなはなです

,but when using たかい the na form isn't used. For example:

> ふじさんはたかいで
>
> ふじさんはたかいやまです

But not

> ふじさんはたかいなやまです




It is because there are い adjectives and な adjectives.

The attributive form of a な adjective ends with な, such as in **きれいな** はな.

The attributive form of an い adjective ends with い, such as in **たかい** やま.

When they are placed before です, in the case of an い adjective, you use the
plain form, such as in ふじさんは **たかい** です. In the case of a な adjective, you use
the stem of the word, such as in さくらは **きれい** です.
