camphor

EnglishEdit
EtymologyEdit
From Old French camphore or Medieval Latin camphora, from Arabic كَافُور (kāfūr), via an Austronesian language such as Malay kapur from Sanskrit कर्पूर (karpūra). It is possible that the Sanskrit term was borrowed from Malay rather than vice versa.

NounEdit
camphor (countable and uncountable, plural camphors)

- I fancied at first the stuff was paraffin wax, and smashed the jar accordingly. But the odour of camphor was unmistakable. It struck me as singularly odd, that among the universal decay, this volatile substance had chanced to survive, perhaps through many thousand years.
- 1895, H. G. Wells, The Time Machine Chapter X,[1]
