What does oxygenate mean?
To oxygenate something is to supply it with oxygen or cause it to take up oxygen. The verb is especially associated with fuel, water, blood, and industrial processes. Oxygenated fuel burns more completely because the added oxygen can improve combustion, while oxygenated water contains additional dissolved oxygen. In medicine, the related term oxygenation describes the process by which blood acquires oxygen in the lungs and carries it to tissues. Oxygenate is more technical than the everyday verb aerate: both can mean introducing air or oxygen, but oxygenate often implies a more precise scientific or chemical treatment. The word is useful wherever a process involves adding oxygen deliberately rather than merely allowing a material to come into contact with air.

Where does oxygenate come from?
Oxygenate was formed in English from oxygen and the suffix -ate, which is widely used in chemical terminology to indicate the addition or attachment of a component. The underlying name oxygen combines the Greek oxys, meaning sharp or acid-forming, with -gen, meaning producing. Words such as oxide and oxidation belong to the same scientific and etymological family.
