What does ionic mean?
Ionic is chiefly used as an adjective in chemistry to describe substances, bonds, or solutions involving ions. An ion is an atom or molecule carrying a positive or negative electrical charge, and an ionic compound generally consists of positively and negatively charged ions held together by electrostatic attraction. In architecture, Ionic names one of the three principal orders of classical Greek architecture, distinguished by slender columns with scroll-shaped ornaments called volutes. The term also appears in the name Ionic Greek, referring to an ancient Greek dialect spoken in Ionia and neighbouring Aegean regions. Although “ionic” and “ironic” sound alike, they have entirely different meanings: one concerns charged particles or the ancient Greek tradition, while the other concerns an indirect expression of criticism or mockery.

Where does ionic come from?
Ionic originally referred to the Ionians and their language: Latin Ionicus came from Greek Iōnikos, meaning “of the Ionians,” with the name ultimately associated with Iōnes. The architectural sense developed through the Ionic order, whose earliest examples were associated with Greek communities in Ionia. The chemical sense arose later from ion, a term formed from the Greek present participle iōn, “going,” and the adjective suffix -ic.
