Etymology: "Cresol" is a blend of two older words: "creosote" and the chemical suffix "-ol." Creosote is the older of the two, a term that came into use in the 1830s for an oily, smoky-smelling substance distilled from tar, and it is itself a coinage built from Greek roots meaning "flesh" and "preserve," because the substance was noticed for its ability to keep meat from rotting. The suffix "-ol" was added to chemical names to mark compounds containing a hydroxyl group, a pattern that echoes the "alcohol" family, where the same ending appears. The name fits the chemistry. Cresols are phenols, a family of compounds that is related to creosote, and they were first isolated from coal tar and wood tar, the same sources that yielded creosote. Once chemists recognized several closely related isomers with the same formula, the word came to name the whole group rather than a single substance. Its use as a disinfectant later followed the same tar-derived tradition that gave creosote its preservative reputation.
