Pronunciation: [vˈɔːtɪsˌiːz] (IPA) 
The word "vortices" is a plural form of "vortex", meaning a powerful whirling motion of fluid or air. The spelling of the word follows the rules of English spelling, with the "o" being pronounced as /ɔː/ and the "e" as /I/ or /iː/, depending on the accent. The plural form is indicated by adding the suffix "-es" to the end of the word. The IPA phonetic transcription for "vortices" is /ˈvɔːtɪsiːz/ or /ˈvɔːtɪsiz/.
Vortices are swirling or rotating patterns of fluid flow that typically take the form of a whirlpool, whirlwind, or vortex ring. These phenomena can be observed in various natural and artificial systems, including water currents, weather patterns, and even air or fluid flow in engineering applications.
In essence, vortices occur when a fluid or gas moves in a rotational motion around a central axis or along a curved path, creating a self-sustaining swirling motion. This swirling motion often results from the interaction of different forces, such as velocity gradients, imbalances in pressure or density, or the presence of rotating objects.
Vortices can vary in scale, ranging from tiny vortices stirred up in a cup of swirling water to immense vortex systems like tornadoes or cyclones. They exhibit distinct characteristics, including the formation of a central core where the fluid or gas velocity is highest and a surrounding region where the fluid rotates around the core.
Understanding vortices is crucial in many scientific fields, including fluid dynamics, meteorology, and aerodynamics. Researchers and engineers study them to comprehend their effects on the surrounding environment, optimize energy efficiency for engineering designs, or predict and mitigate potential risks associated with intense vortices, such as tornadoes or whirlpools.
Overall, vortices represent fascinating and complex phenomena in nature and engineering, characterized by swirling or rotating patterns of fluid or gas flow that have diverse applications across various scientific disciplines.
A whirling or circular motion of water, or such material as sand, forming a kind of cavity in the centre of the circle; an eddy or whirlpool; in Cartesian phil., a collection of particles of a subtile matter, having a rapid rotatory motion around an axis.

The word "vortices" is the plural form of "vortex". The term "vortex" entered the English language in the early 17th century, derived from Latin "vortex" meaning "whirlpool" or "eddy". Latin borrowed it from the Greek word "vórtex" (βόρτεξ) which also referred to a whirlpool or something that revolves swiftly. The Greek word is believed to have originated from the Indo-European root *wer- meaning "to turn" or "to bend". This root is also seen in other related words such as "warp" and "worm".
