 for oxide
From The Collaborative International Dictionary of English v.0.48 :

  Oxide \Ox"ide\ ([o^]ks"[i^]d or [o^]ks"[imac]d), n. [F.
     oxyg[`e]ne oxygen + acide acid: cf. F. oxyde. The French word
     was correctly spelt oxide, till about the year 1840, when, in
     ignorance or forgetfulness of the true history and
     composition of the word, the orthography was change to make
     it represent the [upsilon] of Gr. 'oxy`s, from which it was
     supposed to be directly derived.] (Chem.)
     A binary compound of oxygen with an atom or radical, or a
     compound which is regarded as binary; as, iron oxide, ethyl
     oxide, nitrogen oxide, etc.
     [1913 Webster]
  
     Note: In the chemical nomenclature adopted by Guyton de
           Morveau, Lavoisier, and their associates, the term
           oxides was made to include all compounds of oxygen
           which had no acid (F. acide) properties, as contrasted
           with the acids, all of which were at that time supposed
           to contain oxygen. The orthography oxyde, oxyd,
           etc., was afterwards introduced in ignorance or
           disregard of the true etymology, but these forms are
           now obsolete in English. The spelling oxid is not
           common.
           [1913 Webster] oxidise
