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 is red and beautiful;

赤くてきれいです。
akakute kirei desu

Form -えば - "if" condition

The form "-EBA" [えば] is used to indicate condition, example: if it is red;

赤ければ akakeryay

Form なる - To become

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

Form かった - Past

You can use "KATTA" [かった] which indicates past:

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

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;
