Etymology: "Unmellifluous" is simply the English prefix "un-" (meaning "not") attached to "mellifluous," which itself is built from Latin "mel" (honey) and "fluus" (flowing), so the whole word literally means "not flowing with honey." The sense of something that sounds smooth and sweet is what the base word carries, and the negation reverses it to describe a harsh, grating sound. The word is a straightforward formation rather than a coinage with a famous story: a common English prefix joined to an established adjective. Its value lies in the picture the parts create, a sound so rough it is the opposite of honey poured slowly from a spoon.
