A look into “kakkoii”

➼ Hiragana: かっこいい
➼ Katakana: カッコイイ
➼ Kanji: 格好いい
While the hiragana form かっこいい is the most frequently used one, we can find “kakkoi” written in another two forms, katakana, and kanji, as shown above. The katakana form often appears in contexts such as posters, magazines, comics, or social media like Instagram.
“Kakkoi” can be used as an adjective to describe someone or something as handsome, cool, or good-looking.
Besides, “kakkoi” can be used as individual slang to express one’s feelings as well! 『かっこいい!!』
Also, you can hear young guys, sometimes some adults, use the term カッケー “Kakke-“. This is so-called the 若者言葉 (waka mono kotoba), literally young people’s word. Young people make variations on the end of adjectives or make new words.
Before diving into the definition “kakkoii”, let’s check the pronunciation first!
Please be careful with the way to pronounce “っ”, which is also known as “small tsu” or “silent tsu”, between か and こ. “っ” is derived from “つ (tsu)”, but we don’t have a sound for “っ”. When we have “small tsu” between the words, we should make a pause. Take かっこ (kakko) for example, we can consider each character to be one syllable. In this case, かっこ is made with three syllables and we need to stop for one syllable between か and こ.

The Etymology

Let’s break this adjective into two parts, “kakko” and “ii”, to see how this phrase is formed!
❶ かっこ “kakko”
This part is derived from a noun 格好 (かっこう, kakkou). The definition of this word is “appearance, the figure, or shape”.
❷ いい “ii”
This is an adjective that generally means “good” in English. This is a quite interesting word that can be used both individually or attach with other words. When “ii” is attached with other words, there are two ways.
✎ いい (ii) + noun
- いい匂い (ii nioi): a good smell
- いい夢 (ii yume): a good dream
- いいセンス(ii sensu): a good sense of …
- いい成績 (ii seiseki): a good score
- いい考え (ii kangae): a good idea
✎ noun + が (ga) / は (wa) + いい (ii)
Generally, “いい” means “good”. From the table below, We can see that both “ii” and “yoi” belong to the basic (dictionary) form. But when this word turns into the past tense or negative form, we can only use “yoi”.
Why do we need to know about the conjugation of “いい”? That’s because when we are making a sentence we might want to tell others that something “was” good or something “was not” good.
Basic Affirmative | Affirmative Formal | Negative Formal – 1 | Negative Formal – 2 | |
---|---|---|---|---|
Present Tense | いい / よい ii / yoi | いいです。 ii desu | よくないです。 yoku nai desu | よくありません。 yoku arimasen |
Past Tense | よかった。 yokatta | よかったです。 yokatta desu | よくなかったです。 yoku nakatta desu | よくありませんでした。 yoku arimasen deshita |
With this sentence structure, we can make sentences like below to say something is good.
Japanese | Rōmaji | English |
---|---|---|
今日の天気がいい。 | tenki ga ii | The weather is good today. |
彼は運がいい。 | kare wa un ga ii | He is lucky. |
彼は頭がいい。 | kare wa atama ga ii | He is smart. |
彼は記憶力がいい。 | kare wa kiokuryoku ga ii | He has a good memory. |
The sentences provided above are all in present basic tense, try to change the sentence to past tense or with the negative form!
格好がいい ⇢ ⇢ ⇢ ⇢ かっこいい
kakkou ga ii ⇢ ⇢ ⇢ ⇢ kakkoii
From this structure, we can also find that “kakkoii” is a colloquial form that comes from 格好がいい “kakkou ga ii”.
What is the opposite of “kakkoii”?

As I have mentioned above, the negative form of いい can be よくない or よくありません.
Apart from that, there is an antonym word for いい, which is 悪い ”warui”, literally means “bad”.
Therefore, the opposite of “kakkoii” can be write in かっこ悪い”kakko warui”.
Generally speaking, the difference between “yokunai” and “warui” is that using “warui” to describe something or someone feels too straightforward. Therefore, using “yokunai”, literally means “not good”, is less direct.
