A chemical compound containing two sulfur atoms bonded with another element, particularly used in older chemistry terminology.
From prefix dis- (two) + sulfur + -et (diminutive suffix), combining Latin 'dis' meaning two with the element sulfur, following 19th-century chemical nomenclature patterns that added -et to indicate binary compounds.
This word reveals how chemistry nomenclature has evolved dramatically—modern chemists would call this a disulfide, but Victorian-era scientists used -et and -uret endings that have mostly vanished from our vocabulary, showing how scientific languages transform as knowledge deepens.
