- cone (n.) 1560s, "A solid generated by the revolution of a right-angledan axis" [Century Dictionary], from Middle French cone (16c.) or directly from Latin conus "a cone, peak of a helmet," from Greek konos "cone, spinning top, pine cone," which is perhaps from a PIE root *ko- "to sharpen" (source also of Sanskrit sanah "whetstone," Latin catus "sharp," Old English han "stone"), but Beekes considers it likely a Pre-Greek word.
