The suffix –ol is used in organic chemistry principally to form names of organic compounds containing the hydroxyl (–OH) group, mainly alcohols (also phenol). The suffix was extracted from the word alcohol.

The suffix also appears in some trivial names with reference to oils (from Latin oleum, oil). Examples of this sense of the suffix include benzol, eugenol, urushiol, xylol, and menthol.
