Origin: ME dentdelyon < OFr dent de lion, lit., tooth of the lion < L dens (gen. dentis), tooth + de, of + leo, lion: so called from the jagged leaves
See dandelion in American Heritage Dictionary 4
Origin: Middle English dent-de-lioun
Origin: , from Old French dentdelion
Origin: , from Medieval Latin dēns leōnis, lion's tooth (from its sharply indented leaves)
Origin: : Latin dēns, dent-, tooth; see dent- in Indo-European roots
Origin: + Latin leōnis
Origin: , genitive of leō, lion; see Lion. Word History: Dent-de-lioun, the Middle English form of dandelion, makes it easy to see that our word is a borrowing of Old French dentdelion, literally, “tooth of the lion,” referring to the sharply indented leaves of the plant. Modern French dent-de-lion, unlike Modern English dandelion, reveals to anyone who knows French what the components of the word are. The English spelling reflects the pronunciation of the Old French word at the time it was borrowed into English. The t in dentdelion probably disappeared early in Old French, having been absorbed into the related sound of the d. The earliest recorded instance of the word occurs in an herbal written in 1373, but we find an instance of dandelion used in a proper name (Willelmus Dawndelyon) in a document dated 1363.
