🎨 Japanese Adjectives & Adverbs: The Colorful Paint of Language
Imagine you have a box of crayons. Nouns are like blank coloring book pictures—a cat, a house, a car. But adjectives and adverbs? They’re the COLORS that bring everything to life!
🖌️ The Big Picture: Two Types of Color Crayons
Japanese has two families of adjectives, like having two different crayon boxes:
| Family | What They Look Like | Example |
|---|---|---|
| I-adjectives | End in い (i) | 大きい (ookii) = big |
| Na-adjectives | Need な before nouns | 静か (shizuka) = quiet |
Think of I-adjectives as crayons with caps (the い is the cap). Think of Na-adjectives as crayons that need tape (な) to stick to things!
🟡 I-Adjectives: The Crayons with Caps
What Are They?
I-adjectives always end in the sound い (i). They’re like complete crayons—ready to use!
Common I-adjectives:
- 大きい (ookii) = big
- 小さい (chiisai) = small
- 高い (takai) = tall/expensive
- 安い (yasui) = cheap
- 新しい (atarashii) = new
- 古い (furui) = old
- 暑い (atsui) = hot (weather)
- 寒い (samui) = cold (weather)
Using I-Adjectives
Before a noun: Just put it in front!
大きい犬 (ookii inu) = big dog
At the end: Use it like this!
この犬は大きい (kono inu wa ookii) = This dog is big
🔄 I-Adjective Conjugation: Changing the Crayon Cap
Here’s the magic trick: to change tenses, we swap the cap (change the ending)!
graph TD A["大きい<br>#40;ookii#41;<br>is big"] --> B["大きくない<br>#40;ookikunai#41;<br>is NOT big"] A --> C["大きかった<br>#40;ookikatta#41;<br>WAS big"] C --> D["大きくなかった<br>#40;ookikunakatta#41;<br>was NOT big"]
The Formula (It’s Easy!)
| Form | Recipe | Example with 高い |
|---|---|---|
| Present ✓ | [adjective] | 高い (is expensive) |
| Present ✗ | Drop い → くない | 高くない (is not expensive) |
| Past ✓ | Drop い → かった | 高かった (was expensive) |
| Past ✗ | Drop い → くなかった | 高くなかった (was not expensive) |
Real Examples:
- 今日は暑い (kyou wa atsui) = Today is hot
- 昨日は暑かった (kinou wa atsukatta) = Yesterday was hot
- 今日は暑くない (kyou wa atsukunai) = Today is not hot
- 昨日は暑くなかった (kinou wa atsukunakatta) = Yesterday was not hot
🔵 Na-Adjectives: Crayons That Need Tape
What Are They?
Na-adjectives are sneaky—they don’t look special until you try to stick them to nouns. Then you need な (like tape) to connect them!
Common Na-adjectives:
- 静か (shizuka) = quiet
- 元気 (genki) = energetic/healthy
- 有名 (yuumei) = famous
- 便利 (benri) = convenient
- きれい (kirei) = pretty/clean
- 好き (suki) = liked/favorite
- 嫌い (kirai) = disliked
⚠️ Tricky Alert: きれい and 嫌い end in い but they’re Na-adjectives! Don’t let them fool you!
Using Na-Adjectives
Before a noun: Add な!
静かな部屋 (shizuka NA heya) = quiet room
At the end: No な needed!
この部屋は静かだ (kono heya wa shizuka da) = This room is quiet
🔄 Na-Adjective Conjugation: Adding Different Tape
Na-adjectives change by swapping what comes AFTER them.
graph TD A["静かだ<br>#40;shizuka da#41;<br>is quiet"] --> B["静かじゃない<br>#40;shizuka janai#41;<br>is NOT quiet"] A --> C["静かだった<br>#40;shizuka datta#41;<br>WAS quiet"] C --> D["静かじゃなかった<br>#40;shizuka janakatta#41;<br>was NOT quiet"]
The Formula
| Form | Recipe | Example with 元気 |
|---|---|---|
| Present ✓ | [adj] + だ | 元気だ (is energetic) |
| Present ✗ | [adj] + じゃない | 元気じゃない (is not energetic) |
| Past ✓ | [adj] + だった | 元気だった (was energetic) |
| Past ✗ | [adj] + じゃなかった | 元気じゃなかった (was not energetic) |
Real Examples:
- 彼は有名だ (kare wa yuumei da) = He is famous
- 彼は有名じゃない (kare wa yuumei janai) = He is not famous
- 彼は有名だった (kare wa yuumei datta) = He was famous
- 彼は有名じゃなかった (kare wa yuumei janakatta) = He was not famous
📊 Side-by-Side: Both Types Together
Let’s see how both adjective families change:
| Form | I-adj: 高い (expensive) | Na-adj: 静か (quiet) |
|---|---|---|
| Present ✓ | 高い | 静かだ |
| Present ✗ | 高くない | 静かじゃない |
| Past ✓ | 高かった | 静かだった |
| Past ✗ | 高くなかった | 静かじゃなかった |
Memory Trick:
- I-adjectives: Changes happen to the い
- Na-adjectives: Changes happen after the word
➡️ Adverbs: Making Actions Colorful!
Adjectives describe THINGS (the cat is big). Adverbs describe ACTIONS (the cat runs quickly).
How to Make Adverbs
From I-adjectives: Change い → く
早い (hayai, fast) → 早く (hayaku, quickly)
From Na-adjectives: Change だ → に
静か (shizuka, quiet) → 静かに (shizuka NI, quietly)
graph LR A["早い<br>#40;hayai#41;<br>fast"] -->|い→く| B["早く<br>#40;hayaku#41;<br>quickly"] C["静か<br>#40;shizuka#41;<br>quiet"] -->|add に| D["静かに<br>#40;shizuka ni#41;<br>quietly"]
Examples in Action
| Adjective | Adverb | Sentence |
|---|---|---|
| 早い (fast) | 早く | 早く走る (hayaku hashiru) = run quickly |
| 強い (strong) | 強く | 強く押す (tsuyoku osu) = push strongly |
| 静か (quiet) | 静かに | 静かに話す (shizuka ni hanasu) = speak quietly |
| 上手 (skillful) | 上手に | 上手に歌う (jouzu ni utau) = sing skillfully |
🎭 Manner Adverbs: HOW You Do Things
Manner adverbs answer the question: How do you do it?
Common Manner Adverbs:
- ゆっくり (yukkuri) = slowly
- はっきり (hakkiri) = clearly
- しっかり (shikkari) = firmly
- ちゃんと (chanto) = properly
- そっと (sotto) = gently/softly
Examples:
- ゆっくり歩く (yukkuri aruku) = walk slowly
- はっきり言う (hakkiri iu) = say clearly
- ちゃんと食べる (chanto taberu) = eat properly
These words are already adverbs—no changing needed!
📏 Degree Adverbs: HOW MUCH
Degree adverbs tell us the INTENSITY—like a volume knob!
graph LR A["少し<br>a little"] --> B["まあまあ<br>so-so"] --> C["けっこう<br>quite"] --> D["とても<br>very"] --> E["すごく<br>super"]
The Intensity Scale:
| Adverb | Meaning | Level |
|---|---|---|
| 全然 (zenzen) | not at all | 0% (with negative) |
| 少し (sukoshi) | a little | 20% |
| まあまあ (maamaa) | so-so | 50% |
| けっこう (kekkou) | quite | 70% |
| とても (totemo) | very | 90% |
| すごく (sugoku) | super/really | 95% |
| 本当に (hontou ni) | truly/really | 100% |
Examples:
- この映画はとても面白い = This movie is very interesting
- 少し疲れた = I’m a little tired
- 全然分からない = I don’t understand at all
⚠️ Special Rule: 全然 (zenzen) is usually used with NEGATIVE sentences!
🎯 Quick Summary: Your Color Palette
I-Adjectives (end in い)
- Before nouns: そのまま (just use it)
- Negative: い → くない
- Past: い → かった
- Past Negative: い → くなかった
- Adverb: い → く
Na-Adjectives (need な)
- Before nouns: Add な
- Negative: じゃない
- Past: だった
- Past Negative: じゃなかった
- Adverb: Add に
Adverbs
- Manner: How you do something (ゆっくり, はっきり)
- Degree: How much (とても, 少し, 全然)
