Japanese lesson: い adjectives

There are three types of adjectives in Japanese, and I will be showing you a few of the most common -い adjectives, as well as how to conjugate them to negative, past, and negative past tense. As always, native speakers, please correct me if I'm wrong.

い ajectives conjugate very easily. Below is what can be used for all of these

Past tense: -い、replace with かった (katta)

Negetive: ーい、Replace withくない

Negative past tense: ーい、くなかった

EXAMPLE: あまいーIs sweet

あまくないーIs not sweet

あまかったーWas sweet

あまくなかったーWas not sweet


可愛い(かわいい)kawaii- Cute

高い(たかい)Takai- High/Expensive

安い(やすい)yasui- Cheap

甘い(あまい)amai- Sweet
