How to Write 氨 (ān) — Meaning “Ammonia”

Imagine a gas cloud (气) that smells like ammonia coming from a safe (安) laboratory. The "safe" reminds you of the sound ān, and the gas radical shows it's a chemical gas. This mental picture helps link the shape, sound, and meaning.

When writing 氨, first write the radical 气 (four strokes: left-falling, horizontal, horizontal, hook) then add 安 on the right. The top part of 安 is a roof (宀) covering a woman (女) – be careful to make the 女 narrow to fit beside the radical. Common mistakes include making the 气 too wide or misplacing the hook stroke under the second horizontal.

氨 (ān) means ammonia, a specific chemical gas. 氛 (fēn) means atmosphere or mood, and its right part is 分 (fēn, divide). 氜 (rì) is a rare character for an ancient element (helium-like concept), with 日 (sun) on the right. Visually, the right components differ: 安 vs. 分 vs. 日 – each changes the meaning and pronunciation entirely.

氨 appears mainly in scientific and chemical contexts, such as 氨气 (ammonia gas), 氨水 (ammonia solution), and 氨基酸 (amino acids) in biology. It is not a common daily character, but learners may encounter it in textbooks or product labels for cleaning agents. There is no special cultural symbolism; it is purely a technical term.

Common words containing 氨 include: 氨水 (ān shuǐ) — Ammonia solution; 氨基酸 (ān jī suān) — Amino acid; 氨气 (ān qì) — Ammonia gas.
