Etymology: Earwax has a Latin name built from the word for beeswax. "Cera" is Latin for wax, and the Medieval Latin "caerumen" added the suffix "-men," which turns a substance into a noun for the thing itself, much as "albumen" and "bitumen" do. So the name simply means something like "waxy stuff," chosen because the ear's secretion looks and feels like wax. The spelling and pronunciation carry an oddity. The "u" in "cerumen" has no clear explanation. Etymologists suspect that it was pulled in by the familiar endings of "albumen," the egg white, and "bitumen," the tar-like substance, both of which have the same "-umen" ending. Their resemblance may have nudged the Latin word into its current shape, so the vowel owes more to analogy than to the word for wax.
