What does oxygenized mean?
Oxygenized means treated with, supplied with, or otherwise containing oxygen. The word is encountered especially in commercial and scientific contexts, including oxygenized water, where oxygen has been dissolved into the water, and in descriptions of blood or substances exposed to oxygen. In many everyday situations, “oxygenated” is the more familiar and less specialized term, while “oxygenized” occurs frequently in North American usage and can suggest deliberate chemical treatment. A related sense refers to conversion into an oxide or the process of oxidation, although this is more technical. The distinction matters when describing products: saying that water is oxygenized indicates that it has received additional oxygen, whereas describing it as oxygenated may serve the same purpose in more familiar language. The word derives from the scientific term oxygen and the verb-forming suffix -ize.
Treated with, supplied with, or containing oxygen.
"The manufacturer advertises the water as lightly oxygenized."
“Oxygenated” is more common in general usage; “oxygenized” is especially frequent in North American English.

Where does oxygenized come from?
“Oxygenized” was formed from “oxygen” plus the suffix “-ize,” indicating treatment with or conversion involving oxygen. The underlying term “oxygen” was coined in the late 18th century from Greek roots meaning “acid-forming” and “producer,” in reference to the gas's role in forming acids. Related scientific words include “oxide,” “oxidation,” and “oxygenation,” all of which belong to the same oxygen and oxidation word family.
