The threats of the late 2010s will be qualitatively different.
early 15c., "that produces a (physical) quality," from Medieval Latin qualitativus "relating to quality," from stem of Latin qualitas "a quality, property, nature" (see quality). Meaning "concerned with quality" is from c.1600 in English, from French qualitatif or Medieval Latin qualitativus. Related: Qualitatively.
