These source excerpts show how methyl appears in context. They illustrate usage; the definition above remains the entry’s reference meaning.

  1. You might point out in the theory of oxidation of oils, in development of rancidity in oils, that many methyls accelerate this oxidation of oils.

Etymology

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".
