How to Write 磷 (lín) — Meaning “phosphorus”

Imagine phosphorus as a magical stone (石) that glows like a forest (林) at night. The right side 粦 contains 米 (rice) and two feet (舛) — picture a pile of glowing rice that you step on, and the light comes from the stone below.

Write the left radical 石 first (3 strokes), then the right side 粦 (14 strokes). Pay attention to the bottom part of 粦: it is 舛 (two opposite feet), not 夂 or 夕. A common mistake is making the bottom too wide or missing the right foot stroke; keep the right side balanced with the left.

All three use the 石 radical, but the right parts differ. 磷 has 粦 and means "phosphorus" (a chemical element). 碾 has 展 ("to unfold") and refers to a roller or grinding stone. 磅 has 旁 ("side") and is used as a unit of weight (pound) or the verb "to weigh." Visually, 粦 looks like a rice field with legs, while 展 and 旁 are distinct.

磷 is mainly used in chemistry and agriculture — for example, 磷肥 (phosphate fertilizer) helps plants grow. In folklore, 磷火 (will-o'-the-wisp) refers to blue flames seen over graveyards, caused by spontaneous ignition of phosphorus from decaying bodies, and is often linked to ghost stories.

Common words containing 磷 include: 磷肥 (lín féi) — phosphate fertilizer; 磷火 (lín huǒ) — will-o'-the-wisp; phosphorescent light; 磷光 (lín guāng) — phosphorescence.
