Relating to ions (electrically charged atoms or molecules). Also refers to a classical Greek architectural order characterized by scroll-like capitals.
From Greek 'ion' meaning 'going' (from 'ienai' meaning 'to go'), referring to the movement of charged particles. The architectural sense comes from the Ionian region of ancient Greece where this column style originated.
The same word describes both invisible atomic particles and magnificent ancient columns - both involve movement and structure. Ionic bonds hold atoms together through electrical attraction, while Ionic columns hold up buildings through their distinctive spiral volutes that seem to spiral upward in motion.
