n
a circular movement of water, air, or smoke, causing a small whirlpool or whirlwind
v
(of water, air, or smoke) move in a circular way
Etymology
the word 'eddy' originates from the old english term 'edǣa', which referred to a back-current or a whirlpool. this old english word is likely derived from the prehistoric germanic root 'aith-', meaning 'back' or 'again', a concept intrinsically linked to the circular, returning motion of water. the term's journey into middle english as 'ydy' or 'eddy' solidified its association with a small, swirling current moving against the main flow. its application later expanded metaphorically to describe similar circular motions in air, smoke, or even abstract concepts like thought or activity.
Analysis
this word is a simplex form. it is not productively composed of smaller, independent morphemes in modern english.
