Lesson 52: Conjugating い-adjectives

In this lesson you will learn how to conjugate い-adjectives into the past and the negative form in Japanese. The conjugations are made by replacing the final with a different ending, as shown in the table below.

Positive Negative
Present 〜い 〜く ない です
Past 〜かった です 〜く なかった です

Note the small in なかった, which represents a small pause to lengthen the t sound.

Look at the sentences below to see these conjugations applied in sentences.

English Japanese
It was delicious though it was expensive. おいしかったですけどたかかったです。
oisikatta desu kedo takakatta desu.
I didn't eat the shellfish, though it was delicious. かいべませんでしたけれどおいしかったです。
kai wo tabemasen desita keredo oisikatta desu.
The mountain is not big. やまおおきくないです。
yama ha ookiku nai desu.
This car is not suitable for me. このくるまわたしにふさわしくないです。
kono kuruma ha watasi ni husawasiku nai desu.
It wasn't expensive. たかくなかったです。
takaku nakatta desu.
That was not appropriate. それはふさわしくなかったです。
sore ha husawasiku nakatta desu.

The words けど and けれど have exactly the same meaning: though/although. The difference is that けれど is slightly more formal than けど.
