Lesson 11
Adjectives: な-Adjectives
Introduction to な-Adjectives
In Japanese, descriptive words fall into two major categories: い-adjectives (i-adjectives) and な-adjectives (na-adjectives). While い-adjectives inherently conjugate through their final syllable, な-adjectives behave much like nouns. In dictionary form, they do not end with な; for instance, the word for 'quiet' is simply 静か (shizuka).
They earn the name 'な-adjectives' because the connecting syllable な (na) appears specifically when you use the adjective directly before a noun to modify it. When used alone or at the end of a sentence, the な is dropped.
Common examples of N5 な-adjectives include 静か (shizuka - quiet), 親切 (shinsetsu - kind), 便利 (benri - convenient), and 元気 (genki - healthy/energetic).
Modifying Nouns Directly
To describe a noun directly, place the adjective before the noun and insert な (na) between them. The pattern is: [Na-Adjective] + な + [Noun]. For example, combining 静か (shizuka - quiet) and 町 (machi - town) produces 静かな町 (shizuka na machi), meaning 'a quiet town'.
Here are more examples of direct modification: 親切な人 (shinsetsu na hito - a kind person), 有名な歌手 (yuumei na kashu - a famous singer), and 便利なアプリ (benri na apuri - a convenient app). Notice how な links the descriptor smoothly to the object.
Be careful with 'lookalike' adjectives! Several common words end in the sound 'i' but are actually な-adjectives. The most critical N5 examples are きれい (kirei - pretty/clean), 嫌い (kirai - disliked), and 有名 (yuumei - famous). You must say きれいな花 (kirei na hana - pretty flower), not きれいい花.
Predicative Sentences: Present Tense
When a な-adjective comes at the end of a sentence to make a statement, it drops the な and attaches the polite copula です (desu). The pattern for affirmative statements is: [Topic] は [Na-Adjective] です. For example: この町は静かです (Kono machi wa shizuka desu - This town is quiet).
To make a polite negative statement ('is not...'), drop な and add ではありません (dewa arimasen) or the slightly more conversational じゃありません (ja arimasen). Alternatively, you can say じゃないです (ja nai desu).
For example: この部屋は静かじゃありません (Kono heya wa ja arimasen - This room is not quiet), or 彼は親切ではありません (Kare wa shinsetsu dewa arimasen - He is not kind). Never use くない (kunai) with な-adjectives, as that pattern belongs strictly to い-adjectives.
Predicative Sentences: Past Tense
To describe how something was in the past, な-adjectives borrow the past tense forms of the copula です. For the polite past affirmative ('was...'), drop な and add でした (deshita).
For example: 昨日は暇でした (Kinou wa hima deshita - Yesterday, I was free/had free time), and 旅行は大変でした (Ryokou wa taihen deshita - The trip was tough/hectic).
For the polite past negative ('was not...'), drop な and attach でした to the negative stem, creating じゃありませんでした (ja arimasen deshita) or ではありませんでした (dewa arimasen deshita). A common conversational alternative is じゃなかったです (ja nakatta desu). Example: テストは簡単じゃありませんでした (Tesuto wa kantan ja arimasen deshita - The test was not easy).
Special Uses: 好き (Suki) and 嫌い (Kirai)
In English, 'to like' and 'to dislike' are verbs, but in Japanese, 好き (suki - liked) and 嫌い (kirai - disliked) are な-adjectives. Because they describe a state rather than an action, the item that is liked or disliked takes the subject particle が (ga) rather than the object particle を (o).
The standard structure is: [Person] は [Thing] が 好き / 嫌い です. For example: 私は猫が好きです (Watashi wa neko ga suki desu - I like cats). To express strong feelings, you can prefix them with 大 (dai) to make 大好き (daisuki - love) and 大嫌い (daikirai - hate).
When modifying a noun directly, they follow standard rules by taking な: 好きな食べ物 (suki na tabemono - favorite food) or 嫌いな野菜 (kirai na yasai - disliked vegetables).
