The Difference Between い and な Adjectives
The main difference between い and な adjectives, other than the differences in conjugation, is that い adjectives can be followed by a noun as is, where as な must come between a な adjective and a noun.
For example:
い adjective - 優しい人
--->やさしいひと
---------->kind person(by nature)
な adjective - 親切な人
--->しんせつなひと
----------->kind person(by actions)
Conjugation of い and な Adjectives
The conjugation of い and な adjectives is a bit different.
For い Adjectives:
Non-past Affirmative - As is (~い)
Ex. 嬉しいです(うれしいです)happy
Non-past Negative - replace い with くない
Ex. 嬉しくないです(うれしくないです)unhappy
Past Affirmative - replace い with かった
Ex. 嬉しかったです(うれしかったです)was happy
Past Negative - replace い with くなかった
Ex. 嬉しくなかったです(うれしくなかったです)wasn't happy
For な Adjectives:
Non-past Affirmative - As is (no な)
Ex. 好きです(すきです)like
Non-past Negative - +じゃないです/ではないです/じゃありません/ではありません
Ex. 好きじゃないです(すきじゃないです)dislike
Past Affirmative - +でした
Ex. 好きでした(すきでした)liked
Past Negative - +じゃなかったです/ではなかったです/じゃありませんでした/ではありませんでした
Ex. 好きじゃありませんでした(すきじゃありませんでした)
To Become ~なる
To express the act of becoming something in Japanese, we use the う verb ”なる”
When used with い and な adjectives it looks somethings like this:
い Adjective くなる *get rid of い!!*
Ex. 可愛くなります(かわいくなります)to become cute
良くなる(よくなる)to become good *いい is irregular so it becomes よく not いく!*
暑くなる(あつくなる)to become hot *i.e. weather*
な Adjective になる *no な!!*
Ex. 変になります(へんになります)to become strange
有名になる(ゆうめいになる)to become famous
嫌いになる(きらいになる)to come to dislike
