Determinative form of い-adjectives

The second form of the い-adjective is the determinative form. This serves to qualify the noun it accompanies.

たかい ほん expensive book (book which is expensive)

The determinant precedes the determined noun. It is an absolute rule in Japanese.

それは むずかしいほんです。 That is a difficult book.

これは おもしろいえいがです。 This is a interesting film.

たかいネクタイです。 It is a expensive necktie.
