2481: nicotine Sep 27, 2021

Tobacco is native to Central America, hence the word coming to English from Spanish, and likewise there was a Portuguese connection—albeit more convoluted—for 'nicotine'. It is named from the New Latin 'nicotiana', which is the scientific name of the plant, 'nicotiana herba', and that word comes from the name of the French ambassador to Portugal, who brought tobacco back to France in 1560: Jean Nicot. It is unclear where that name originates.
