broom: [OE] Broom was originally the name of the yellow-flowered bush; its application to the long-handled brush did not come about until the 15th century (the underlying notion is of a brush made from broom twigs tied to a handle). The plant-name occurs throughout the Germanic languages, but it is applied to quite a wide range of plants: Old High German brāmma, for instance, is a ‘wild rose’; Old Saxon hiopbrāmio is a ‘hawthorn bush’; and English bramble probably comes from the same source. => bramble[broom etymology, broom origin, 英语词源]
