- mingle (v.)
- mid-15c., "to bring together," frequentative of Middle English myngen "to mix," from Old English mengan (related to second element in among), from Proto-Germanic *mangjan "to knead together" (source also of Old Saxon mengian, Old Norse menga, Old Frisian mendza, German mengen), from a nasalized form of PIE root *mag- "to knead, fashion, fit" (see macerate).
The formation may have been suggested by cognate Middle Dutch mengelen. Of persons, "to join with others, be sociable" (intransitive), from c. 1600. Related: Mingled; mingling.
