'high-sulfide' originates from the combination of 'high,' meaning 'great in amount or degree,' and 'sulfide,' which refers to a compound of sulfur with another element.

The term 'sulfide' comes from the French word 'sulfure,' which was derived from the Latin 'sulfur.'

Initially, 'sulfide' referred to any compound containing sulfur, and 'high-sulfide' specifically denotes a high concentration of such compounds.
