- mingle (v.) mid-15c., "to bring together," frequentative of M.E. myngen "to mix," from O.E. mengan (related to second element in AMONG (Cf. among)), from P.Gmc. *mangjan "to knead together" (Cf. O.S. mengian, O.N. menga, O.Fris. mendza, Ger. mengen), from PIE *mag- "to knead, fashion, fit" (see MACERATE (Cf. macerate)). The formation may have been suggested by cognate M.Du. mengelen. Of persons, "to join with others, be sociable" (intrans.), from c.1600. Related: Mingled; mingling.
