The Full Story
Latin18th centurywell-attested
From Latin 'pollen' (fine flour, mill dust), genitive 'pollinis,' from earlier 'pollis' (fine flour), related to 'pulvis' (dust, powder), from PIE *pel- (dust, flour, fine substance). The word was adopted as a botanical term by Carl Linnaeus in 1760, who observed that the fine powder produced by flowers resembled the flour-dust of a mill. Before Linnaeus, the substance had no standard scientific name. The semantic transfer
Did you know?
Pollen grainsarenearly indestructible. Their outerwall (the exine) is made of sporopollenin, one of the most chemically resistant organic compounds known. Pollen can survive in sediments for millions of years, making palynology (the study of fossil pollen) a powerful tool for reconstructing past climates
'palúnō' (to sprinkle) share the same root. The journey from grinding grain to the microscopic world of plant reproduction captures how Latin agricultural vocabulary was repurposed for Enlightenment-era science. Key roots: *pel- (Proto-Indo-European: "dust, flour").
