   • 1895 May 29, H[erbert] G[eorge] Wells, chapter X, in The Time Machine: An Invention, London: William Heinemann, →OCLC:

     Now, I still think that for this box of matches to have escaped the wear of time for immemorial years was a strange, and for me, a most fortunate thing. Yet oddly enough I found here a far more unlikely substance, and that was camphor. I found it in a sealed jar, that, by chance, I supposed had been really hermetically sealed. I fancied at first the stuff was paraffin wax, and smashed the jar accordingly. But the odour of camphor was unmistakable.

• odōs
• olor

Via rhotacism from Old Latin odōs (plural: odōses). The further etymology is slightly unclear. De Vaan suggests that it derives from Proto-Italic *odōs, from Proto-Indo-European *h₃ed-.^[1] The term may be compared to Old Armenian հոտ (hot), perhaps indicating that both forms derive from a neuter s-stem *h₃éd-os. Such a development would, however, require that the Latin term was originally neuter.^[2]
