Mid 19th century: from Greek keras, kerat- 'horn' + -in1.
rhinoceros from Late Middle English:
It is the look of the rhinoceros that provides its name, which comes from Greek rhino- ‘nose’ and keras ‘horn’. The animal has been known in English since the end of the 14th century, but the first reference to it calls it a kind of unicorn. Rhino- will be familiar to gardeners from the antirrhinum (mid 16th century), the alternative name for the snapdragon, whose name means ‘counterfeiting a nose’ from its appearance, while keras appears in keratin (mid 19th century), the substance from which horn is made.
