Etymology
Origin of panther1
First recorded before 1000; from Latin panthēra, from Greek pánthēr; replacing Middle English pantere (from Old French, from Latin ) and Old English pandher (from Latin )
Origin of Panther2
First recorded in 1965–70
Explanation
A panther is a large, black leopard. Panthers are related to the kitty purring in your lap, but they're ten times bigger. When most people think of a panther, they picture a black panther, which is really a leopard with an all-black coat. Strictly speaking, a panther can also be a puma, which is a brown cat that's similar in size to a jaguar. Panther is a Greek word meaning "leopard," and it became commonly (and confusingly) applied to both pumas and cougars in the 18th century.
