Pronounced: BELL-tane, noun
Notes: I knew a little about this word, but could not properly define it.
The word quaquaversal means “sloping downward from a center in all directions”
It comes from Latin: quaqua (in all directions). Note that quaqua comes from qua (in what direction). To quaqua is added versus (towards).
The word came into English in the late 1600s
