How to Write 卫 (wèi) — Meaning “to guard; to protect; hygiene”

Imagine the left stroke as a person standing at attention, and the right part 卩 looks like a bent arm or a shield. Together they form a guard who is ready to protect — so 卫 means "to guard." Think "a defender with a shield (卩) by their side."

卫 has only 3 strokes: first write the left horizontal stroke (like a short line), then the vertical stroke downward, and finally the hook-like 卩 on the right (horizontal, then vertical with a curve). A common mistake is making the left part too wide or forgetting that the right part 卩 should not be separated — it is one continuous stroke.

卩 is just the right half of 卫 without the left stroke — it means "seal" or is a radical, never used alone. 卬 (yǎng) looks like 卩 but has an extra upward stroke on the left and means "to lift" or is an ancient word for "I." 卫 always has the left component (a short horizontal and vertical stroke) and means "guard" or "hygiene."

卫 appears in common words like 卫生间 (bathroom) and 卫生 (hygiene), where it implies protecting health. It is also in 卫星 (satellite), literally "guard star," reflecting the idea of a protective celestial body. Culturally, 卫 is often used in names of security forces or protective institutions, such as 警卫 (security guard).

Common words containing 卫 include: 卫生间 (wèi shēng jiān) — bathroom; restroom; toilet; 卫生 (wèi shēng) — hygiene; sanitation; health; 卫星 (wèi xīng) — satellite.
