An oxidation/reduction reaction (also known as a "redox" reaction) involves the transfer of electrons. The first definition of oxidation was indeed about oxygen, and meant that an element or compound gained oxygen atoms. However, we eventually came to understand that these chemical reactions frequently involved a transfer of electrons. When an atom loses electrons, it is oxidized. The atom that gains electrons is said to be reduced.
