Ion means "something that goes" in Greek. Scientific term introduced by Faraday 
in his Experimental Researches in Electricity, seventh series (1834):

665. Finally, I require a term to express those bodies which can pass to the 
electrodes, or, as they are usually called, the poles. Substances are 
frequently spoken of as being electro-negative, or electro-positive, according 
as they go under the supposed influence of a direct attraction to the positive 
or negative pole. But these terms are much too significant for the use to which 
I should have to put them; for though the meanings are perhaps right, they are 
only hypothetical, and may be wrong; and then, through a very imperceptible, 
but still very dangerous, because continual, influence, they do great injury to 
science, by contracting and limiting the habitual views of those engaged in 
pursuing it. I propose to distinguish such bodies by calling those anions158 
which go to the anode of the decomposing body; and those passing to the 
cathode, cations159; and when I have occasion to speak of these together, I 
shall call them ions.
