The word "eddy" is often spelled with the letters E-D-D-Y in English. In IPA (International Phonetic Alphabet) transcription, this word is spelled /ˈɛdi/. The first sound is an open-mid front unrounded vowel, represented by the symbol /ɛ/. The second sound is a voiced alveolar stop, represented by the symbol /d/. The final sound is an open-mid front unrounded vowel, represented by the same symbol /ɛ/. The spelling "eddy" accurately reflects these phonetic sounds.
An eddy refers to a circular or swirling movement of water, air, or any fluid substance. It is typically formed when a current encounters an obstacle or irregularity in its flow, causing the fluid to replenish itself and overturn in a contained area. Eddies can commonly be observed in rivers, streams, and oceans, as well as in the atmosphere.
In aquatic environments, an eddy can be characterized by a circular motion in which the water rotates back on itself. This swirling action tends to create a counter-flow or a circular current within the larger body of water. The size and strength of an eddy can vary significantly, ranging from barely noticeable to a powerful whirlpool capable of trapping and pulling objects or even causing temporary disturbances on the surface.
In meteorology, eddies refer to small-scale air currents that can develop within larger atmospheric systems. These rotating pockets of air can influence weather patterns, driving local changes in wind speed, humidity levels, and temperature. Eddies in the atmosphere can often be observed in the form of dust devils, tornadoes, or smaller vortices created by the interaction of wind with terrain features or temperature gradients.
Overall, the concept of an eddy encompasses the circular motion of fluids and the formation of localized, swirling currents. From water bodies to the atmosphere, eddies play a vital role in shaping and influencing various natural processes and phenomena.
• A current of water contrary to the main stream; a circular motion of water; a whirlpool.
• To move, as an eddy.

The term was later influenced by the Old Norse word "itha", meaning "whirlpool". However, the exact etymology of the word "eddy" is not entirely clear.
