As with some words saying this word is more complicated than the definition of the word. However, its use on maps is legendary.

Not complicated,
Marked on my treasure map,
It’s decussated.

“Could be the King’s “X”,
Or maybe buried treasure,
The spot has been marked. “

This word sure seems fun,
I would like to use it more,
A smarty-pants word.

“In old-time comics,
To indicate a dead man,
Decussated eyes. “
