Kanji study
Kanji that look alike.
Some kanji differ by a single stroke, others by a single component. Here are the most common traps, and the detail to look for.
The classic traps
A longer stroke, an extra dot: the difference is all in one detail.
未 (not yet): the top stroke is the shorter one. 末 (end): the top stroke is the longer one.
土 (earth): the bottom stroke is longer, like the ground. 士 (warrior): the top stroke is longer.
日 (sun): one bar inside, 4 strokes. 目 (eye): two bars, 5 strokes, taller.
人 (person): the right stroke leans on the left one. 入 (enter): the other way round.
大 (big) has no dot. 犬 (dog): a dot at the top right. 太 (thick): a dot at the bottom, in the middle.
午 (noon): the vertical stroke stops under the top stroke. 牛 (cow): it pokes through the top.
千 (thousand): the top stroke slants. 干 (dry): it is flat.
天 (heaven): the top stroke sits apart, above. 夫 (husband): the vertical stroke pokes through the top.
右 (right) has 口 at the bottom, 左 (left) has 工. Stroke order differs too: 右 starts with the slant, 左 with the horizontal.
本 (book) = 木 (tree) plus a short stroke at the bottom. So 休 (rest) contains 木, and 体 (body) contains 本.
百 (hundred) = 白 (white) with a horizontal stroke on top.
自 (self) = 目 (eye) with a short slanted stroke on top.
玉 (jewel) = 王 (king) with a dot at the bottom right.
力 (power): the second stroke pokes out at the top. 刀 (sword): it doesn't.
Same 目 on top. 貝 (shellfish) ends with two short splayed strokes, 見 (see) with two “legs” 儿.
島 (island) takes 鳥 (bird), drops its four dots and adds 山 (mountain): a bird resting on a mountain.
