Reasoning from etymology can lead you down some pretty misleading trails, especially since a lot of the most popular etymologies are nonsense and words are not obligated to change with our understanding. For example, "atom" comes from a Greek term meaning something which cannot be cut, as in something indivisible, but we apply the term to physical objects we now know are quite divisible indeed. Computer programmers still use atomic in the old sense, certainly. Also, reasoning from an etymology hardly anyone knows is not going to get you any insight into what others mean.
