Etymology

"Willy-nilly" originated as a reduplication of "will I, nill I" (Middle English "nill" meaning "to be unwilling"). The phrase condensed over time to its current form, reflecting the tension between willingness ("will") and reluctance ("nill"). It evolved from a literal expression of choice ("whether one wants to or not") to a broader sense of randomness or lack of control.
