About
The character "氧" was created in the 19th century to designate the chemical element oxygen, deriving from the earlier Chinese term "養氣" that highlighted its role in sustaining life. It is structured as a phono-semantic compound, incorporating the semantic component "气" to denote its gaseous state and the phonetic component "羊" to approximate the sound of the related character "養". Since its inception, "氧" has consistently referred solely to the element oxygen without alteration in its core meaning.
