What does oxidated mean?
Oxidized describes something that has undergone oxidation, a chemical process in which a substance reacts with oxygen or another oxidizing agent. The term is especially common in discussions of metals: iron becomes oxidized and may rust, copper can develop a green patina, and silver may turn black or tarnish. It can also describe substances more generally that have been changed by an oxidizing reaction, including foods, biological tissues, and chemical compounds. As a verb, oxidized is the past tense and past participle of oxidize, so a sentence may use it both to report a completed reaction and to describe a resulting condition. The word is technical in its most precise sense but familiar in everyday descriptions of corrosion and discoloration.
Having undergone oxidation; converted into an oxide or altered through reaction with oxygen or another oxidizing agent.

Where does oxidated come from?
The word belongs to the family of oxide, oxidation, and oxidize. Oxide entered English through French and is associated with Greek oxys, meaning “sharp,” a reference historically connected with acids and their sharp taste. Oxidation was formed from oxide with the suffix -ation, and oxidize developed from oxidation with the suffix -ize. The related word oxygen was coined in the late 18th century from the same Greek root combined with -gen, meaning “producing.”

Easily confused with oxidated
Oxidized describes a substance that has been chemically converted by oxidation, whereas oxidized can also be understood more broadly as affected by oxidation or corrosion.
Oxidized refers specifically to the chemical process of oxidation, while corroded describes the broader physical damage that may result from it.
