Keiyoushi – Japanese adjectives of type i [い]

In the Japanese language, adjectives can be divided into 2 types, those that end in “i” [い] and those that end in “na” [な]. In this article, we are going to learn a little about Japanese endings and “i” [い] adjectives called keiyoushi.

Japanese adjectives are words that attribute a quality or characteristic to nouns. A. Adjectives of the type [い] have this name because they end with the letter [i].

So whenever you come across a Japanese word that ends with [い] before a noun, it's probably an adjective.

Conjugating adjectives ending with i [い]

There are several ways to conjugate adjectives in [い]. One of them is using suffixes like:

• です – Desu is a polite way of ending sentences with adjectives;
• くない – Kunai is a negative way of saying that something is not a given adjective;
• なる – Becoming and Transforming;
• かった – Past;

Form くない – Negative

To conjugate an adjective as negative, just replace the [い] with [くない]. See an example of the negative sentence: It's not cool;

凄くないです
Sugokunai desu

Form く- Link with て

The “KU” [く] also serves to link a sentence using the form te [て] as in the sentence: It's red and beautiful;

赤くてきれいです。
akakute kirei desu

We recommend reading: Te (て) - How does this form work in Japanese?

Form -えば – “if” condition

The form “-EBA” [えば] is used to indicate condition, eg if it is red;

赤ければ akakeryay

なる Form – Becoming

Ending adjectives with “NARU” [なる] (means to become or transform), you can create the following expressions: My room will be bigger;

私の部屋は広くなる watashi no heya wa hirokunaru

かった Form – Past

You can use “KATTA” [かった] which indicates past tense:

• furukatta ie [古かった家] House that was old;
• sugokatta desu [凄かったです] It was cool;
• sugokunakatta [凄くなかった] It wasn't cool;

There are other ways too, but we won't go into details, so as not to confuse too much. Not to mention that there are many ways to merge the adjective with the verbs. We will leave, below, some other forms of conjugation:

• souda [そうだ] Indicates appear to be. With the exception of ない (なさそう) and よい;
• kattari [かったり] Indicates a momentary situation;
• kunakattari [くなかったり] Negative form of かったり;
