"evergreen shrub," late 14c., from Latin iuniperus (source of French genièvre, Spanish enebro, Portuguese zimbro, Italian ginepro), of uncertain origin, perhaps related to iunco "reed." Watkins has it from PIE *yoini-paros "bearing juniper berries," from *yoi-ni- "juniper berry." Applied to various North American species from 1748. In the Bible, it renders Hebrew rethem, the name of a white-flowered shrub unrelated to the European evergreen.
