camphor ball
LowFormal/Historical/Technical
Definition
Meaning
A small, hard ball made from camphor, used to repel moths and other insects from stored clothing.
A solid, white, aromatic moth repellent, historically common before the advent of synthetic alternatives like paradichlorobenzene. The term is also used metaphorically to describe something old-fashioned or having a strong, distinctive smell.
Linguistics
Semantic Notes
A highly specific term for a dated household product. In contemporary usage, often replaced by the generic 'mothball'. The phrase 'put in camphor balls' can be used figuratively to mean 'to store away or preserve'.
Dialectal Variation
British vs American Usage
Differences
The term is archaic in both dialects. 'Mothball' (or specifically 'camphor mothball') is the more common modern term in both. Historically, 'camphor ball' was standard for the specific camphor-based product.
Connotations
Conveys a sense of antiquity, strong smell, and careful storage. In the UK, it might be slightly more recognized due to older housing stock and traditions of storing woollens.
Frequency
Extremely low in contemporary speech and writing, found primarily in historical texts, antique contexts, or technical descriptions of traditional pest control.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'шар камфоры' (a ball made *of* camphor for other purposes). 'Camphor ball' is a fixed compound for a moth repellent.
- The Russian term 'нафталиновый шарик' refers to naphthalene balls, a different but functionally similar product. Ensure context matches the specific chemical.
Common Mistakes
- Misspelling as 'camper ball' or 'camphor bowl'.
- Using it as a verb (to camphor-ball something is non-standard; 'to mothball' is used).
- Confusing it with modern cedar balls or other natural repellents.
