pollen: [16] Pollen originally meant ‘flour’ in English. Not until the 18th century was it taken up as a botanical term. It was borrowed from Latin pollen ‘powder, dust, flour’, a relative of pulvis ‘dust’ (source of English powder and pulverize) and polenta ‘pearl barley’ (source of English polenta [16]). => polenta, powder, pulverize
pollen (n.)
1760 as a botanical term for the fertilizing element of flowers (from Linn?us, 1751), earlier "fine flour" (1520s), from Latin pollen "mill dust; fine flour," related to polenta "peeled barley," and pulvis (genitive pulveris) "dust," from PIE root *pel- (1) "dust; flour" (cognates: Greek poltos "pap, porridge," Sanskrit pálalam "ground seeds," Lithuanian pelenai, Old Church Slavonic popelu, Russian pépel? "ashes").
