Christopher Williams shares this unicorn-related word:
Eburnean
-adjective
a.) Made of or like ivory.*
b.) Ivory-colored.
[Origin: From Latin eburneus meaning "ivory." ]
*The horn of the unicorn, though typically considered to be eburnean (probably due to its association in the Middle Ages with the tusk of the narwhal), was originally described as red, white, and black by Ctesias (the origin of which most likely lies in its significance as an ancient calender symbol).

Q. What's black and white and red all over?
U. My horn!

Gary Barwin exclaims:
Thanks for eburnean!
"the single horn of the exclamation mark, the shadow of a unicorn surmounted by its long eburnean shadow, a distant comet and its swart trail."
