Definition
Meaning
A white, volatile, crystalline substance with a strong aromatic odor, obtained from the wood of the camphor tree (Cinnamomum camphora).
A substance used historically and in traditional medicine as a topical analgesic, a mild expectorant, and as a moth repellent. More broadly, it refers to any synthetic or natural substance with similar properties.
Linguistics
Semantic Notes
Primarily a concrete noun for a specific chemical/plant product. Use is now restricted due to toxicity concerns, making the term less common in modern everyday contexts.

Common Pitfalls
Translation Traps (for Russian speakers)
- Not to be confused with 'камфара' (kamfara), which is the direct translation and correct.
- Avoid false cognates like 'камфор' (incorrect ending) or confusing with 'кофе' (coffee).
Common Mistakes
- Misspelling as 'camper', 'camphour', or 'camfer'.
- Mispronouncing the 'ph' as /f/ alone; it's /mf/ in the cluster.
- Using it as a verb (e.g., 'to camphor something').

FAQ
Frequently Asked Questions
Pure camphor is toxic if ingested and can be harmful in large amounts. Modern over-the-counter products contain safer, synthetic versions or highly diluted amounts.
It has a very strong, penetrating, medicinal, and slightly woody aroma, often associated with mothballs and chest rubs.
No, 'camphor' is solely a noun. You cannot 'camphor' something. You would say 'treat with camphor' or 'use camphor on'.
Yes, but its use is more regulated. It is found in some topical pain relievers, inhalants, and as a preservative in limited applications. Its use in mothballs has largely been replaced by paradichlorobenzene or naphthalene.
