Pronunciation

Forms

éthyle m (plural éthyles)[1]

Etymology

It is formed from French éther + -yle, the first part being the stem of the noun for ether.[2][3][4] The suffix is taken from Ancient Greek ὕλη (hū́lē, “wood, later matter”), a word of unknown origin, so that the name means literally ether of wood.[3][5][6] Picoche traces éther to Ancient Greek αἰθήρ (aithḗr, “bright upper air”), from αἴθω (aíthō, “to kindle, burn”).[6] The FEW files the word under Latin aether.[7]

Earliest recorded meaning

It is first recorded in 1840 in the French translation of J. Liebig's Traité de chimie organique, as the name of a chemical radical.[2][8]

Semantic evolution

The word names the monovalent radical C₂H₅, made of carbon and hydrogen, that enters into many organic compounds, ordinary alcohol among them.[3][9] Littré still defined it in 1873 as a compound obtained by decomposing ethyl iodide with zinc.[10]

Its derivatives came quickly: éthylique “containing the ethyl radical” (1850, as in alcool éthylique), éthylène (1867) and éthylamine (1850).[3] Because ethyl alcohol is ordinary alcohol, two derivatives passed into general use: éthylisme (1890), a learned synonym of alcoolisme, and éthylique “alcoholic” (1890); éthylomètre (1982) was proposed to replace alcootest.[3] By a change of suffix the word also gave éthane (1880), from which éthanol (1910) was formed.[3]

Timeline

  • 1840 – First recorded, in the French translation of Liebig's treatise on organic chemistry.[2][8]

  • 1855 – Nysten's medical dictionary records it.[5][8]
  • 1867 – Éthylène is recorded.[3]

  • 1982 – Éthylomètre is coined.[3]
