mandrel

Etymology

Taken from French mandrin, probably from Vulgar Latin *mamphurinum, itself from Latin mamphur (“a bow drill”), which goes back ultimately to Oscan or Ancient Greek μαννοφόρον (mannophóron, “wearing a collar”), formed from μανά (maná, “collar”) and φέρω (phérō, “to bear”); the first element is cognate with Latin monile (“collar”).
