Etymology: Estrone is a chemical name built from pieces of Greek and Latin, and its most surprising ingredient is a word for frenzy. The Ancient Greek "oîstros" meant a gadfly, the biting insect that drives cattle wild, and it came to mean a frenzy or sexual impulse. Latin borrowed it as "oestrus," the term for the heat cycle of animals, and English scientists took the stem "estr-" from that root when naming the hormone family. The rest of the name is pure chemistry. "Keto-," from German "Keton" (the root of English "ketone"), marks a carbonyl group in the molecule, and "-one" is the standard chemical ending that signals a ketone. Put together, the name describes a ketone derived from the estrus-related hormone family, rather than anything about the substance's biological role in a poetic sense.
