Origin
Borrowed from German Methyl; compare French méthyle. French chemists Jean-Baptiste Dumas and Eugene Peligot, after determining methanol's chemical structure, introduced "methylene" from the Ancient Greek μέθυ (méthu, “wine”) + ὕλη (húlē, “wood, material”) with the intention of highlighting its origins, "alcohol made from wood (substance)". The term "methyl" was derived in about 1840 by back-formation from "methylene", and was then applied to describe "methyl alcohol".
