look up any word, like pussy:
A didem (from Latin didus 'did' and emu 'em' ) is a mythological creature. Sometimes they are referred to as water nymphs.
Oh for a Didem of fire, that would ascend

The brightest heaven of invention,

A kingdom for a stage, princes to act

And monarchs to behold the swelling scene!
