Meaning
中 means middle, inside, and center. Few kanji turn up as often in everyday Japanese — it appears in words for physical locations, time expressions, school grades, and ongoing actions. Learn this one character and dozens of common words start clicking into place.
The character is a pictograph: a vertical stroke pierces the center of an oval or rectangular shape. One reading, あたる (to hit, to be correct), reflects this directly — the line strikes the target dead center. A second interpretation sees a flag planted at the midpoint of a territory boundary, marking a fixed center around which everything is arranged.
中 is a Grade 1 kanji, one of the first taught in Japanese elementary school. It takes just 4 strokes. Its radical is ｜ (bō) — the vertical line that runs straight through the middle of the character, a fitting symbol for what it means.

あた.る (ataru) means to hit or be on target. The link to 中 is etymological: the character originally depicted an arrow striking the exact center of something.

Memory Tip
Think of an archer's target: one vertical stroke drives straight through the center. That stroke is 中 — neither left nor right, exactly in the middle and inside the boundary. Both meanings, middle and inside, live in that single line. For Vietnamese learners, the reading TRUNG echoes familiar words: trung tâm (center) and trung học (secondary school).
