mite 1 (mīt)
Any of numerous small or minute arachnids of the order Acarina, certain species of which are parasitic on animals and plants, infest stored food products, and in some cases transmit disease.
contraction of minute, from the Latin minutum, the translation of the Greek word lepton, the very smallest bronze of copper coin (Luke 12:59; 21:2). Two mites made one quadrans, i.e., the fourth part of a Roman as, which was in value nearly a halfpenny. (See FARTHING.)
