"Jove" is the
ablative form of the name of
Jupiter, head of the
Roman pantheon. Like most
Latin words, it comes into
English and other languages mainly through the ablative case.
(Another example would be the ablative of
amor,
amoris, m., "
love" -- its ablative
form,
amore, can be found in several of the
Romance languages.)
It is interesting to note that Latin once did not contain the
letter J, and thus the name was
spelled "Iove." Also, the Latin letter
V was once used interchangeably with the letter
U, and
was pronounced as such, sounding like the English letter
W. Thus "Jove" was pronounced more like
"Yoh-weh."
When you see how much that resembles the
Hebrew "
YHWH," it's hard to avoid making
snide little
comments.
