Today’s scene

How it works

A な-adjective in a polite predicate looks like a noun plus です. この部屋は静かです。この店は便利です。There is no な before です. Students who just learned 高いです try 静かなです. That extra な is a spare chair in the aisle.

Before a noun, な is required. 静かな部屋, 便利なコンビニ, きれいな写真, 好きな飲み物. The な is a linker, not a flavor word. Remove it and Japanese hears two nouns colliding.

好き and 嫌い are な-adjectives. The liked thing is marked with が: コーヒーが好きです。猫が好きです。この町が好きです。を is for verbs like 食べます. 好きです is not that verb. If you say コーヒーを好きです, you have put an object marker on a word that does not take objects that way.

きれい, 有名, 元気, 暇, 簡単, 親切, 好き, 嫌い, 静か, 便利, にぎやか. Learn them as a closed box this week. にぎやか is the noisy twin of 静か — useful when the guesthouse street wakes up.

な-adjectives look like nouns that learned to describe. That is a useful lie. 静かです behaves like 学生です on the surface: stem, then です. The difference shows up when a noun follows. 学生の部屋 needs の. 静かな部屋 needs な. Two linkers, two jobs. If you put の after 静か, you have made a ghost possession. If you put な after 学生, you have invented a fake adjective.

The predicate rule is the one students break first. They learned 高いです, saw い sitting there, and decided every description wants a cushion before です. So they produce 静かなです, 便利なです, 好きなです. Japanese does not want that cushion. 静かです. 便利です. 好きです. Save な for the moment a noun is about to be modified: 静かな部屋, 便利な店, 好きな飲み物.

きれい is the celebrity trap. It ends with い. It is not an い-adjective. Test it: きれいな写真 works. きれいくないです does not. Negative present for this family is きれいじゃないです or きれいではありません. We will not drown you in every negative variant this hour. Know that you cannot run the くない machine on きれい, 有名, 元気, or 好き.

好き is the sentence you came to Japan already wanting. English “I like coffee” makes coffee an object. Korean 커피를 좋아해요 also uses an object marker. Japanese refuses that picture. 好き is a な-adjective meaning, roughly, “liked / likable” as a state. The thing in that state is marked with が: コーヒーが好きです. Read it as “coffee is liked (as for me, understood).” You may still put 私は in front: 私はコーヒーが好きです. は marks the person who likes. が marks the liked thing. を is unemployed here.

You will hear を好きになる in other kinds of sentences later. That is a different verb construction. This classroom’s rule for beginner-10 and beginner-17 is blunt on purpose: 好きです takes が. 嫌いです takes が. 猫が嫌いです. Same shelf.

A working list for a guesthouse week: 静か, にぎやか, 便利, きれい, 有名, 元気, 暇, 簡単, 親切, 好き, 嫌い. 暇です means you are free, not that you are bored in the English teenage sense. 元気です is how you answer お元気ですか, and also how you say someone looks well. 簡単です is “it’s simple” — useful when staff slow down for you and you want to say the machine is not hard.

Pronunciation: 静か is shi-zu-ka, four beats if you count し as one. Do not turn it into “shizka”. 便利 is ben-ri, not “benly”. 好き is su-ki. The う in すき is not an English “soo” held long. きれい is ki-re-i, three beats, and that final い is why your eyes betray you.

If you speak Mandarin, 安静 and 方便 will map, but do not copy 的 onto な as if they were twins. な is not 的. If you speak Korean, 조용하다 → 静かです is fine conceptually; 좋아하다 → 好きです is where 을/를 will poison が. Drill が until 를 feels like the foreign particle. If you speak English, stop translating “like” as a verb that must take を. If you speak Spanish, me gusta is actually a better cousin than “I like”: the liked thing is the grammatical subject-like piece. Use that intuition, then still say が, not a Spanish clitic.

Dialogue notes: 外はにぎやかです sets a topic contrast. Inside, Mina wants quiet. 静かな部屋が好きです stacks this lesson twice — な before 部屋, が before 好き. That one line is the exam. 便利な場所です uses な because 場所 is a noun. この町が好きです does not need な because 好きです is the predicate, not 好きな町.

Polite register stays. 静かだ, 好きだ, きれいだ are dictionary casual. Not this room. Not a staffed lounge. です.

Do not dump とても on every line. とても静かです is legal. 静かです already works. Intensity words become a nervous tic for beginners who do not trust a short sentence.

Practice: describe the room you are in. 静かです or にぎやかです. Then name one liked drink with が. Then put な in front of a noun you can see: きれいな窓, 便利な袋. If you write を好き, erase it before you stand up.

Next is not more adjectives. Next is numbers and the clock, because shops and stations will not wait for your feelings. You will come back to 好き in beginner-17 and beat が until it stays.

Drill the two positions until they bore you. Column A, predicate: 静かです, 便利です, きれいです, 好きです, 元気です, 暇です. Column B, before a noun: 静かな部屋, 便利な店, きれいな写真, 好きな飲み物, 元気な人, 暇な日. Read A, then B, then A. The な should feel like a click that only happens when a noun is coming. If な still appears before です, you are clicking in the wrong place.

暇です deserves a social footnote. It can mean you have free time. In some rooms it can sound like you are underemployed. As a traveler saying 今日は暇です, it is usually “I’m free today”. As a self-introduction at a company, pick a different adjective. This classroom is a guesthouse, not a job interview.

有名です is useful on stations and sweets. この寺は有名です。 You may not need to produce 有名な yet, but you will read 有名な on a sign. 親切です is what you say about people who slowed down for you. Do not say 私は親切です unless you enjoy sounding like a poster.

Negative of な-adjectives: 静かじゃないです is what you will hear. 静かではありません is extra pressed-shirt. Both are polite enough. じゃありません also exists. Pick じゃないです or ではありません and stop collecting. Do not run くない on this family.

Vietnamese, Thai, and Indonesian speakers often already live with adjectives that do not inflect like European languages. Use that calm. Then still insert な before a Japanese noun. Hindi speakers: do not map का/की/के onto な. な is not a gender-and-case ending. Arabic speakers: な is not a sun-letter assimilation. It is one mora, na, always.

A useful contrast set to say aloud: この部屋は静かです。静かな部屋です。この町はにぎやかです。にぎやかな町です。この店は便利です。便利な店です。コーヒーが好きです。好きな飲み物はコーヒーです。 That last pair is the exam inside the exam. If you can say both, な and が are both employed.

Do not apologize in English for liking quiet. Say 静かな部屋が好きです. It is a complete adult sentence. It also stacks this lesson’s two jobs in one line, which is why the dialogue put it in Mina’s mouth on purpose.

When you copy from a phone translator, watch for を好き. Many engines still leak it. You are the editor. Change it to が before you speak. The store clerk is not your proofreader.

Homework is one room, one street, one liked drink, one liked place. Four sentences. Record. Listen for a stray なです and a stray を好き. Erase both. Then go outside in your head and say 便利です about a convenience store you have not entered yet. You will enter it in beginner-20.

です versus な + noun

Predicate: 静かです。 It is quiet. (no な)
Before a noun: 静かな部屋 a quiet room
便利な店 a convenient shop
きれいな写真 a pretty photo

好き takes が

X が 好きです。
コーヒーが好きです。 I like coffee.
この部屋が好きです。 I like this room.
Not: コーヒーを好きです。

Sentences you can use

Close, but not this

OK この部屋は静かです。
NG この部屋は静かなです。

な links to a noun, not to です. Predicate = stem + です.

OK コーヒーが好きです。
NG コーヒーを好きです。

好き is not 食べます. The liked item takes が. We will drill this again in beginner-17 because it does not stick the first time.

Say it out loud

Numbers and clock time are next — 一 to 十 on the page, and 何時ですか at a desk. Keep saying が好きです until を feels wrong in your mouth.
