Etymology: Pinene is a chemical name built from two pieces: "pine," the familiar tree, and the suffix "-ene," which chemists use for hydrocarbons containing carbon-carbon double bonds (as in "benzene" or "ethylene"). The "pine" element traces back to Latin "pinus," the word for the pine tree, so the name literally points to the plant the compound comes from. Pinene is a noun for the terpene found in pine resin and turpentine, and it is one of the most abundant of the natural terpenes. The name follows the systematic pattern chemists adopted to label compounds by their source, so a reader can tell from the word alone that it is a hydrocarbon associated with pines.
