How to Write 砗 (chē) — Meaning “Giant clam (used in 砗磲)”

Imagine a giant clam shell so large and hard that it could crush a car (车) made of stone (石). The image of a stone car being crushed by a clam shell helps link the left radical 石 and the right component 车 to the meaning "giant clam."

The left radical 石 should be written narrow and slightly smaller than the right part 车. Pay attention to the stroke order of 车: write horizontal, then left-slanting stroke, then vertical, and finally horizontal again. A common mistake is making the left and right sides the same width, but the right side should be slightly wider.

砗 (giant clam) has the right component 车, while 矶 (jī, a rock projecting over water) has the right component 几, and 矸 (gān, a type of stone) has the right component 干. Their meanings are all related to stone, but only 砗 refers specifically to a marine animal shell. Visually, the right side shapes are distinct: 车 vs. 几 vs. 干.

砗 is almost exclusively used in the word 砗磲 (chē qú), which means giant clam, often referring to the beautiful white shell used in jewelry and Buddhist artifacts. You may also see 砗磲贝 (giant clam shell) and 砗磲珠 (giant clam bead). In Chinese culture, the shell is valued as a symbol of purity and is sometimes carved into ornaments.

Common words containing 砗 include: 砗磲 (chē qú) — Giant clam; 砗磲贝 (chē qú bèi) — Giant clam shell; 砗磲珠 (chē qú zhū) — Giant clam bead.
