Disulphoxid

/dɪˌsʌlˈfɑkˌsɪd/ noun

Definition

An older chemical term for a compound containing two sulfur atoms and oxygen, similar to a disulfoxide.

Etymology

From dis- + sulph- + ox- (oxygen) + -id (binary compound suffix), an archaic nomenclature combining Latin and chemical naming conventions from the 19th century.

Kelly Says

This word is virtually extinct in modern usage—it's the kind of term you'd only find in dusty 1870s chemistry textbooks, replaced entirely by more standardized nomenclature.
