3. A clear, colorless liquid hydrocarbon derived from petroleum, commonly used to dissolve substances in industrial applications

Etymology: Xylene is a chemical coinage, built from two pieces rather than inherited from an ancient language. The first part, "xyl-", comes from the Greek "xylon," meaning wood, and it entered chemistry because the compound was first isolated from wood tar, a by-product of distilling wood. The second part, "-ene," is the standard chemical suffix marking an unsaturated hydrocarbon with a double bond, the same ending found in benzene and ethylene. So the name is a kind of label that records the substance's origin in the form of its own chemistry. Its meaning is fixed by that construction: a hydrocarbon of the benzene-related family that carries two methyl groups, which is why it exists as several isomers with nearly identical names. The "wood" in the name is therefore a memory of where the compound was first found, not a description of what it is today, since commercial xylene is now made mostly from petroleum.
