What does whiplash mean?
Whiplash most commonly names a neck injury caused by sudden, forceful movement of the head, especially in a vehicle collision. It can involve pain, stiffness, headache, dizziness, and reduced neck movement, although symptoms vary and the term describes the mechanism of injury rather than a single diagnosis. The word also has a figurative meaning: a rapid, destabilizing change or reversal that leaves people, organizations, or markets feeling as if they had been suddenly struck. In that sense, “the whiplash effect” is common. As a verb, whiplash is rare and literary, normally meaning to strike or lash with a whip. The word’s imagery is vivid: a whip snaps forward, and similarly a sudden change can propel people from stability into confusion. Understanding both the medical and figurative senses explains why whiplash is useful in conversations about accidents, policy changes, market volatility, and rapid social disruption.
A neck injury caused by the sudden, forceful movement of the head, especially during a vehicle collision; also, figuratively, a rapid and destabilizing change.

The medical sense is common in both British and American English. The figurative sense is especially frequent in political, economic, and social commentary.

Whiplash can describe both a neck injury and a change so sudden it leaves everyone reeling.
