Etymology
[edit]Borrowed from other European languages, probably French méthane or German Methan, words, in turn, coined in the late 1860s on the basis of méthyle or Methyl (with the final yl removed because of its wrong identification with a formative suffix) and the suffix -an, invented and proposed in 1866 by German Chemist August Wilhelm van Hoffmann to indicate a chain of carbon atoms with no double bonds.
