Latin and Slavonic for `moon'

[Anthony Appleyard]

[ moderator re-formatted ]

{luna} means "moon" in Latin and also in Russian. But Palmer's book "The
Latin Language" says that Latin {luna} < *{louksna:} [= "the white object",
after the old IE word *{ma:n-} or similar became taboo due to superstition].
Is the Russian form a loanword from Latin (which seems unlikely) or parallel
evolution?

How can I get a copy of Palmer's book "The Latin Language"?
