Word Origin & History
equerry
1591, short for groom of the equirrie, from esquiry "stables," from M.Fr. escuerie, perhaps from M.L. scuria "stable," from O.H.G. scura "barn;" or from O.Fr. escuier "groom," from V.L. scutarius "shield-bearer." In either case, spelling infl. by L. equus "horse," to which it is not related.
