Modern English
lanolin

Imagine a sheep walking through rain with its own built-in waterproofing system: its sebaceous glands coat the wool with a waxy secretion that helps water slide away. In 1885, the German physician Mathias Eugenius Oscar Liebreich gave that material a compact laboratory name by joining Latin lāna, “wool,” with oleum, “oil,” and the scientific suffix -in. The oil part has a surprisingly Mediterranean family tree: Latin oleum came from Greek ἔλαιον, “olive oil,” making lanolin a linguistic meeting point between a woolly sheep and an olive grove. Older English already had lanigerous, “wool-bearing,” from Latin laniger, but lanolin was the word that stuck in pharmacies and cosmetics. And although people still call it “wool fat,” lanolin is chemically a wax rather than a true fat—so the sheep is wearing a waterproof wax coat, not carrying a tiny jar of butter.
