History
Etymology
From Ancient Greek Ἴων (Íōn).
Borrowed from Romanian Ion.
From the ending of anion and cation, which in turn is from Ancient Greek ἰόν (ión, “going”), neuter present participle of εἶμι (eîmi, “I go”). Coined by English polymath William Whewell in 1834 for Michael Faraday, who introduced it later that year.
From a reduction of I don't.
