rhinoceros [LME] It is the look of the rhinoceros that provides its name, which comes from Greek rhino- ‘nose’ and keras ‘horn’. The first English reference to it calls it a kind of unicorn. Rhino- will be familiar to gardeners from the antirrhinum [M16th], the alternative name for the snapdragon, whose name means ‘counterfeiting a nose’ from its appearance, while keras appears in keratin [M19th], the substance from which horn is made.
