How to say "cyanide" in Japanese
Choosing the right word
- シアン化合物シアンかごうぶつnounA technical chemical term for cyanide compounds, built on the katakana シアン. It appears in chemistry and safety contexts but is less common overall; it is rarely needed outside specialized discussion.
- シアン化物シアンかぶつnounA shortened equivalent of シアン化合物, also denoting cyanide as a chemical substance. Like its longer counterpart it is a technical term of limited commonness, encountered mainly in chemistry writing.
- 青化物せいかぶつnounA Sino-Japanese way of writing cyanide, from 青 'blue'. It is less common than the katakana terms and is a marginal choice for learners; シアン化合物 or シアン化物 is usually what you want.
All three are technical chemical terms for cyanide; 「シアン化合物」 is the katakana-based form, 「シアン化物」 a shorter equivalent, and 青化物 the Sino-Japanese variant, all uncommon in everyday use.
