köken: 1560s, from Middle French cone (c. 16th century) or directly from Latin cōnus (“cone; peak of a helmet”), from Ancient Greek κῶνος (kônos, “cone, spinning top, pine cone”), perhaps from Proto-Indo-European * ḱeh₃- (“to sharpen”). Cognate to Sanskrit शित (śita, “sharpened”), Latin catus (“sharp”), Old English han (“stone”)).
köken: First attested in the Yongbi eocheon'ga (龍飛御天歌 / 용비어천가), 1447, as Middle Korean 솘〮바ᅌᅩᆯ〮 (Yale: swól-s-pàngwól). From 솔 (sol, “pine”) + -ㅅ- (-s-, genitive interfix; omitted from the spelling, but this causes the tense phonation of the following consonant) + 방울 (bang'ul).
