Japanese: conjugating i-adjectives

Hello everyone! ^^
How are you all doing?

In this post I will talk about i-adjectives in Japanese and how to conjugate them.

Let's learn some adjectives𝆕

Happy = 嬉しい (うれしい - ureshii)
Sad = 悲しい (かなしい - kanashii)
New = 新しい (あたらしい - atarashii)
Cute = 可愛い (かわいい - kawaii)
Expensive = 高い (たかいい - takai) ; it can also mean 'High'
Cheap = 安い (やすい = yasui)

Alright!^^

Now, let's conjugate these adjectives^^

They are all in the present tense. Let's make them in the past tense now.
Here is how to do it in Japanese:
First, note that these adjectives end with (い - i). So, to conjugate them to the past tense, we do the following:

Drop (い - i) and replace it with かった (katta).

That is really all you need to do!
Isn't it easy?! I love Japanese! 😍

So, to say I was happy , you say: 嬉しかった。(ureshi katta)
Try to make the past tense of the remaining adjectives!

Now, how about negating them?
Do you know how to say I am not happy ? (I hope you never need to say this sentence!♡)

Since 嬉しい ,which means happy, is an i-adjective, then we drop the (い) and, this time we replace it with (くない - kunai).
→ I am not happy =
嬉しくない (ureshi kunai).
Easy peasy! LOL

Now, for i-adjectives, you know how to form the:
Present tense: affirmative and negative.
Past tense: affirmative.

How about past tense negative?

Here is how:
Present tense affirmative: 嬉しい (ureshii)
→ Present tense negative: 嬉しくない (ureshikunai)
→ Make it in the past tense by dropping い and adding かった
→ 嬉しくなかった  (ureshi kuna katta) = was not happy. 

You can follow this conjugation rule with all of the i-adjectives, including 欲しい which means want that we talked about before.
You can read my post about the usage of (hoshii) here:How To Say: 'I Want Something (A NOUN)' in Japanese .

欲しい  = want
欲しくない  = don't want
欲しかった  = wanted
欲しくなかった  = didn't want
