No, reduction is not specifically defined as a reaction with oxygen. Reduction refers to the gain of one or more electrons by an atom, ion, or molecule. This gain of electrons often involves a decrease in charge or a decrease in oxidation state. While some reduction reactions may involve the addition of oxygen, reduction itself is not exclusively defined by this.
