methyl-, methy- +

(Greek: a combining form occurring in the names of chemical compounds in which the methyl group is present; alcohol, wine)

A "univalent hydrocarbon radical," 1844, from German methyl (1840) or French méthyle, back-formation from French méthylène, coined in French (1835) from Greek methy, "wine" + hyle, "wood". The word was introduced by Swedish chemist Jöns Jakob Berzelius (1779-1848).

A methyl with hydroxide replacing the hydrogen atoms.
methanol (s) (noun),
The simplest of the aliphatic alcohols, a colorless, volatile, flammable, toxic liquid: "Methanol, which is also called methyl alcohol, or wood alcohol, was originally obtained by the distillation of wood and is used in chemical synthesis, as a solvent, and as an alternative fuel."
A colorless flammable liquid, CH3OCH2OCH3, used as a solvent and in the manufacture of perfumes, adhesives, and protective coatings.
A toxic flammable gas produced by the decomposition of organic matter and synthesized for use as a solvent and in the manufacture of many products; such as, dyes and insecticides.
1. Any derivative of methyl alcohol, as sodium methylate.
2. Any compound containing the methyl group.
1. Relating to the group of atoms derived from methane containing one carbon atom and two hydrogen atoms.
2. A hydrocarbon radical not known in the free state, but regarded as an essential residue and component of certain derivatives of methane; such as, methylene bromide, formerly called methene.
3. Methylene blue, an artificial dyestuff consisting of a complex sulphur derivative of diphenyl amine.
4. Originally: a hydrocarbon radical present in wood spirit (which consists chiefly of methanol).
Pertaining to or characteristic of the methyl group.
A microorganism that is capable of growing upon reduced carbon compounds containing no carbon-carbon bonds; such as, methanol, methane, and methylamine.
