How to Write 礤 (cǎ) — Meaning “grater”

Imagine a stone (石) with a rough surface that you use to grate vegetables, and think of the sound "tsah" like the noise a grater makes. The right part 察 can be remembered as "cha" sounding like "chop"—you chop and then grate the food.

Pay attention to the left side: the radical 石 should be narrow and sit high, with the bottom stroke turning into a short upward flick. The right side 察 has many strokes; keep the top part (宀) compact and make sure the bottom 示 has three dots evenly spaced—common mistakes are making the left side too wide or the right side too cramped.

Although all share the stone radical, 礤 specifically means a kitchen grater, while 磴 refers to stone steps or a mountain path, and 磷 means phosphorus (a chemical element). Visually, 礤 has 察 on the right, 磴 has 登 (dēng, to ascend), and 磷 has 粦 (lín, related to firefly or phosphorus). Their pronunciations and uses are completely distinct.

You would see 礤 in a kitchen context, especially when talking about tools like 礤床 (grating board) or 礤子 (a handheld grater). For example, you might say "把土豆用礤床礤成丝" (grate the potatoes into shreds using the grating board). It is a practical character used in cooking instructions or when shopping for kitchen utensils.

Common words containing 礤 include: 礤床 (cǎ chuáng) — grating board; 礤子 (cǎ zi) — grater (kitchen tool); 礤菜 (cǎ cài) — to grate vegetables.
