How to Write 栋 (dòng) — Meaning “ridgepole; pillar; classifier for buildings”

Picture a large wooden pillar standing at the east side of a building — the left side is 木 (wood) and the right side is 东 (east). This image links the character to both its meaning (a building's main beam) and its sound (dòng, like "dong" of a bell).

Write the left radical 木 first with the order: horizontal, vertical, left-falling, right-falling. Then write 东 on the right: horizontal, left-falling, vertical hook, small left-falling, dot. A common mistake is making the right part too wide — keep the whole character balanced and the 木 stroke that crosses should not extend too far right.

栋 specifically means ridgepole, pillar, or a classifier for buildings, while 杆 (gān) refers to long thin poles or rods, and 杈 (chà) means a tree fork or a branch. Visually, 栋 has 东 on the right, 杆 has 干, and 杈 has 叉; each has a different radical and right part that changes the meaning.

栋 is commonly used as a classifier for buildings, like 一栋楼 (yī dòng lóu, a building) and 几栋 (jǐ dòng, several buildings). It also appears in the metaphor 栋梁 (dòng liáng), meaning the pillar of society or a key supporting person, similar to how ridgepoles support a roof.

Common words containing 栋 include: 一栋楼 (yī dòng lóu) — a building; 几栋 (jǐ dòng) — several (classifier for buildings); 栋梁 (dòng liáng) — pillar (of society); backbone; ridgepole and beam.
