How to Write 误 (wù) — Meaning “mistake”

Imagine that you are speaking (讠) and someone says "Woo!" (吴 sounds like "woo") because you made a big mistake. This creates a visual and sound association: speaking and hearing "woo" equals a mistake. It helps you recall both the pronunciation and the meaning.

Write the speech radical 讠 first (2 strokes: a dot then a horizontal line that curves down). Then write 吴 carefully: first the small 口 (3 strokes) on top, then the larger 天 below (4 strokes). A common mistake is making the left radical too small or squeezing the right part, so keep them balanced in size.

All three use the speech radical 讠, but the right parts differ. 误 uses 吴 and means "mistake"; 证 uses 正 (meaning "correct") and means "proof" or "certificate"; 诂 uses 古 (meaning "ancient") and means "to explain old words." Visually, 证 has a straight 正 on the right, 诂 has 古, and 误 has 吴 with a mouth-like top.

You often see 误 in words like 错误 (mistake), 误会 (misunderstanding), and 耽误 (to delay). For example, if you misunderstand someone, you say "误会了." The character also appears in formal settings, like 误点 (late arrival for a train or flight).

Common words containing 误 include: 错误 (cuò wù) — Error / Mistake; 误会 (wù huì) — misunderstanding; 耽误 (dān wù) — to delay; to hold up.
