Japanese Adjectives for Beginners: 40 i- and na-Adjectives

🇯🇵 Japanese · 40 cards · A1 · by Haruka Sato

These are the 40 adjectives my beginner students reach for first: big, small, expensive, delicious, busy, kind. Japanese has two types, and you need to know which is which before you can finish a sentence: i-adjectives (高い, 楽しい) conjugate by themselves, while na-adjectives (便利な, 静かな) take な before a noun and じゃない to go negative.

Two traps. 綺麗(きれい)and 嫌い(きらい)end in い but behave like na-adjectives. And 暑い and 熱い are both atsui — one is the weather, one is your coffee, and only the kanji tells you which.

Every card has kanji, kana and romaji, plus one sentence you can use as it is. Read the examples out loud.

Questions about this deck

How do I tell an i-adjective from a na-adjective?
An i-adjective ends in い that belongs to the word itself (高い, 楽しい, 忙しい) and conjugates on its own: 高くない, 高かった. A na-adjective needs な before a noun (便利な店, 静かな部屋) and uses じゃない/でした to change form. The catch is 綺麗(きれい)and 嫌い(きらい): they end in い but are na-adjectives, so it's 綺麗な人 and 嫌いじゃない. Learn those two as exceptions from day one.
How do I make these adjectives negative and past?
For i-adjectives, drop the い: 大きい → 大きくない (not big), 大きかった (was big), 大きくなかった (wasn't big). いい is irregular: よくない, よかった. For na-adjectives, change the copula: 便利じゃない (not convenient), 便利でした (was convenient), 便利じゃなかった. In polite speech, add です: 大きくないです, 便利じゃないです (or the stiffer 便利ではありません).
What is the difference between 暑い and 熱い? They sound the same.
Both are read atsui. 暑い is for air and weather: 今日は暑い (it's hot today). 熱い is for what you touch, eat or drink: 熱いお茶 (hot tea), 熱いお風呂 (a hot bath). Their cold counterparts split the same way — 寒い for weather, 冷たい for objects and drinks. In speech only context distinguishes them, which is why the kanji matters.
Why is it 猫が好きです and not 猫を好きです?
好き, 嫌い, 上手 and 下手 are adjectives in Japanese, not verbs, so they can't take the object marker を. The thing you like, hate or do well is marked with が: 猫が好きです (literally "cats are likeable [to me]"), 日本語が上手です. To add the person, use は for the topic: 私は猫が好きです.
