Word Origin & History

mite  (1)
"tiny animal," O.E. mite, from P.Gmc. *miton (cf. M.Du. mite, O.H.G. miza, Dan. mide) originally meaning perhaps "the cutter" (from P.Gmc. *mait-, cf. Goth. maitan, O.H.G. meizen "to cut") in reference to its bite. More likely etymology is that its original sense is "something small" (from PIE *mei- "small") in reference to size.
