い Adjectives

In Japanese, adjectives play a crucial role in describing nouns, much like in English. One of the two main types of adjectives in Japanese is the い adjectives (ikeiyoushi). These adjectives end with the syllable "い" (i) in their dictionary form and are essential for anyone aiming to become proficient in the language.

What are い Adjectives?

い adjectives are versatile and can be used to describe a wide range of characteristics, including size, color, shape, and emotional states. Unlike な adjectives (na adjectives), which require the particle "な" (na) when modifying a noun, い adjectives can directly precede a noun.

An い adjective in its basic form can be used directly before a noun to describe it. For instance:

かわいい ねこ。 - A cute cat

おいしい たべもの。 - Delicious food

たかい ビル。 - A tall building

Changing Tenses and Politeness Levels

Present Affirmative: The adjective stays in its dictionary form.

あたらしい くるま が ほしいです。 - I want a new car

Present Negative: To form the negative, replace the final "い" with "くない".

この りょうり は おいしくない です。 - This food is not delicious

Past Affirmative: Replace the final "い" with "かった".

きのう の しけん は むずかしかった。 - Yesterday's exam was difficult

Past Negative: Replace the final "い" with "くなかった".

その えいが は おもしろくなかったです。 - That movie was not interesting

Using い Adjectives in Sentences

Here are a few more examples to illustrate how い adjectives can be used in different contexts:

あつい ひ が つづいています。 - Hot days are continuing

かれ は やさしい ひと です。 - He is a kind person

この ほん は とても おもしろい。 - This book is very interesting

ふゆ の あさ は さむい。 - Winter mornings are cold
