vortex
VOR-teks
/ˈvɔː.teks/
A mass of whirling fluid or air, especially a whirlpool or whirlwind.
Refers to a spiral motion of fluid around a central axis, creating a low-pressure zone in the middle.
The story behind the word. The Latin verb 'vertere' means 'to turn'. This gave rise to 'vortex' (a turning mass of water) and 'vertex' (the highest turning point of a hill or angle). Both words share the core concept of rotation and turning.

- whirlpool: Whirlpool is used specifically for water, while vortex can apply to any fluid, including air, gas, or plasma.

Memory hook
Think of a 'vortex' as a 'vort-ical' (vertical) spinning axis of water. Vortex = Vertically spinning whirlpool.
When not to use
Do not use for a simple straight wind or linear current; it must involve spinning or spiraling.
Fun facts
- Airplanes create powerful invisible vortices at their wingtips that can linger in the air for minutes, which is why planes must space out during takeoff.
