I-Adjectives and Na-Adjectives

Now i wish you can learn more about the adjectives so i make it more easier for you to learn.

There are two types of adjectives in Japanese: i-adjectivesand na-adjectives. I-adjectives all end in "~ i," though they never end in "~ ei" (e.g. "kirei" is not an i-adjective.)

Japanese adjectives differ from their English counterparts. Although Japanese adjectives have functions to modify nouns like English adjectives, they also function as verbs when used as predicates. For example, "takai(高い)" in the sentence "takai kuruma (高い車)" means, "expensive". "Takai(高い)" of "kono kuruma wa takai (この車は高い)" means not just "expensive" but "is expensive". When i-adjectives are used as predicates, they may be followed by "~ desu(~です)" to indicate a formal style. "Takai desu (高いです)" also means, "is expensive" but it is more formal than "takai (高い)".

Here are lists of common i-adjectives and na-adjectives.

Modifying Nouns

When used as modifiers of nouns, both i-adjectives and na-adjectives take the basic form, and precede nouns just like in English.

I-Adjectiveschiisai inu
小さい犬
small dog
takai tokei
高い時計
expensive watch
Na-Adjectivesyuumeina gaka

I-Adjectives as Predicates

As mentioned on the previous page, adjectives can function like verbs. Therefore, they conjugate just like verbs (but probably much more simply).

InformalPresent NegativeReplace the final ~ i with ~ ku nai
PastReplace the final ~ i with ~ katta
Past NegativeReplace the final ~ i with ~ ku nakatta
FormalAdd ~desu to all of the informal forms.
There is also a variation in the formal negative forms.
* Negative: Replace ~i with ~ku arimasen
* Past Negative: Add ~ deshita to ~ku arimasen
These negative forms are considered slightly more polite than others.

Here is how the adjective "takai (expensive)" is conjugated.

InformalFormal
Presenttakai
高い
takai desu
高いです
Present Negativetakaku nai
高くない
takaku nai desu
高くないです
takaku arimasen
高くありません
Pasttakakatta
高かった
takakatta desu
高かったです
Past Negativetakaku nakatta
高くなかった
takaku nakatta desu
高くなかったです
takaku arimasen deshita
高くありませんでした

There is only one exception to the rule of i-adjectives, which is "ii (good)". "Ii" derives from "yoi," and its conjugation is mostly based on "yoi".

InformalFormal

ii desu

Present Negativeyoku nai

良くありません
Pastyokatta
良かった
yokatta desu
良かったです
Past negativeyoku nakatta
良くなかった
yoku nakatta desu
良くなかったです
yoku arimasen deshita
良くありませんでした

Na-Adjectives as Predicates

They are called na-adjectives because "~ na" marks this group of adjectives when directly modifying noun (e.g. yuumeina gaka). Unlike i-adjectives, na-adjectives cannot be used as predicates themselves. When a na-adjective is used as a predicate, the final "na" is deleted and followed by either "~ da" or "~ desu (in formal speech)". As with nouns, "~ da" or "~ desu" changes its form to express the past tense, the negative, and the affirmative.
