Etymologies

New Latin Platypūs, former genus name, from Greek platupous, flat-footed : platu-, platy- + pous, foot.
(American Heritage® Dictionary of the English Language, Fourth Edition)
From Medieval Latin Platypus (originally a genus name, but already used for a type of beetle), from Ancient Greek πλατύπους (platypous, "flat-footed"), from πλατύς (platys, "flat") + πούς (pous, "foot"). (Wiktionary)

  • Another odd thing about this is that the ending is often pronounced with a full /-pʊs/. I wonder whether this is a relic of its coming from Greek -πους, or whether it's by association with the other furry animal name 'puss'.

    Oh, and Platypus is a genus of beetles. When they came to name the monotreme they gave it this genus name, but it was subsequently discovered the beetles have priority, so platypuses got reassigned to Ornithorhynchus.

  • "Jack, I cannot tell you how I long to see a platypus."

    "I remember you spoke of it last time we were there."

    "A damnable, a hellish last time it was too, upon my soul... New Holland is gravely in my debt."

    "Never mind. It will be much better this time. You shall watch great flights of platypuses at your leisure."

    "My dear, they are mammals, furry animals."

    "I thought you said they laid eggs."

    "So they do. That is what is so delightful. They also have bills like a duck."

    "No wonder you long to see one."
