Etymology: Vincristine is a chemical coinage, built from parts that each record a different stage of its discovery. The "vin" comes from "vinca," the name of the periwinkle genus, whose alkaloids are the family of compounds to which the drug belongs. The middle element is the Latin "crista," meaning a tuft or crest, and in this case it refers to the tuft of leaves on the plant. The ending "-ine" is the common chemical suffix used for alkaloids and other nitrogen-containing compounds. The result is a name that reads like a description of its source: a crest-like leaf tuft on a periwinkle, reduced to a chemical name. Because the word is a modern technical formation, it does not appear in older English and its parts were assembled deliberately rather than inherited or drifting through speech over centuries.

Synonyms: oncovin, leurocristine
