After two years of daily study I can read N2 news articles. But there are still 12 kanji that make me stop, squint, and pull up the dictionary. Not because I never learned them — because they look almost identical to something else I learned first.
Here are the 12 troublemakers and the radical-based tricks that finally separated them in my head.
Pair #1: 持 (hold) vs 侍 (samurai)
Both contain 寺 on the right. The left radical is the whole story.
Trick: 持 has 扌 (hand). A hand holds things. 侍 has 亻 (person). A person at a temple is a samurai. Whenever I blank, I ask: what’s on the left, a hand or a person?
Pair #2: 待 (wait) vs 持 (hold) vs 特 (special)
Three-way trap. All end in 寺.
Trick: 待 has 彳 (step/crossroads). You step-wait at a crossroads. 特 has 牛 (cow). A special cow at the temple — unusual enough to remember.
Pair #3: 末 (end) vs 未 (not yet)
Literally one stroke different. The top horizontal is longer on 末, shorter on 未.
Trick: 末 = “long top = final top = end.” 未 = “short top = the top hasn’t grown yet = not yet.”
Pair #4: 土 (earth) vs 士 (samurai/scholar)
Same deal, flipped. Top is shorter or longer by one stroke width.
Trick: 土 = top short, base wide, like a pile of earth spreading out. 士 = top long, base short, like a samurai standing tall with broad shoulders.
Pair #5: 人 (person) vs 入 (enter)
The classic beginner confusion, and it still catches me in handwriting.
Trick: 人 starts with a long diagonal, then a short one. 入 starts with a short one, then a long one. A person leads with their big step; entering you tiptoe first.
Pair #6: 太 (fat/thick) vs 大 (big) vs 犬 (dog)
All 大 with or without a dot.
Trick: 大 is plain — just big. 太 has a dot inside — the extra belly makes it fat. 犬 has a dot on top — imagine a dog’s ear flopping up.
Pair #7: 体 (body) vs 休 (rest)
Both 亻 + tree/base on the right.
Trick: 体 = person + 本 (root/base) — the body is a person’s base. 休 = person + 木 (tree) — a person resting under a tree.
Pair #8: 王 (king) vs 玉 (jewel) vs 主 (master)
Three similar shapes.
Trick: 王 plain = king. 玉 = king with a dot (the royal jewel). 主 = king with a crown dot on top (the master wears the crown).
Pair #9: 右 (right) vs 石 (stone) vs 古 (old)
All variations on a box + stroke.
Trick: Notice which side the opening faces and what’s on top. 右 has 𠂇 hand on top — your right hand. 石 has 丆 on top like a cliff overhang — stones fall from cliffs. 古 has 十 on top — ten generations = old.
Pair #10: 買 (buy) vs 貝 (shell) vs 見 (see)
All share 目/貝-ish shapes.
Trick: 貝 is the base shell. 買 puts a “net” on top — you buy shells by netting them (historically shells were money). 見 has legs under an eye — an eye walking around seeing.
Pair #11: 発 (departure) vs 登 (climb)
Both share the 癶 top.
Trick: 発 has a springy curve below — things launch/depart. 登 has 豆 (bean/stand) below — you climb up onto a stand.
Pair #12: 侯 (marquis) vs 候 (season/weather)
This one haunts N2. Literally one tiny stroke difference.
Trick: 候 has a vertical stroke cutting through the middle — “time cuts through the seasons.” 侯 doesn’t have that stroke. If I see the stroke, it’s season. No stroke, marquis.
The Real Fix: Radical-Aware SRS
All 12 of these stopped tricking me once I started reviewing kanji alongside their radicals. When your SRS card shows 持 with 扌 highlighted, your brain encodes “hand-holds” instead of just the whole shape. Look-alike recall becomes structural instead of visual.
Every kanji card shows its radicals, mnemonics and look-alike warnings. JLPT-aligned decks, OCR scan for real-world reading, lock-screen widget for dead time.
If You’re Stuck On a Specific Pair
Take the two kanji, write them side by side ten times, highlight the one stroke or radical that differs, and make one sentence that uses both. The contrast is what the brain remembers, not either kanji alone.
Two years in, these 12 still occasionally ambush me. But now I know the tricks. And the gap between “that one” and “the other one” is a quarter-second instead of a dictionary lookup.
