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 い with a different ending, as shown in the table below.
〜く ない です
〜く なかった です
Note the small っ 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.
