Etymology

Description

It is a yellow, non-metal element belonging to group 16 in the periodic table. It is an important element for living organisms as it is required in the amino acids cysteine and methionine, and therefore in many proteins. It is absorbed by plants from the soil as sulfate ion.

Language Of Origin

Latin, Proto-Indo-European language

Origin Of Word

From the Latin word sulfur, meaning "hell fire"

Meaning

From the Proto-Indo-European word swelp meaning "to burn"

Symbol Origin

Latin sulfur

Etymological Description

The word entered Medieval English from the Anglo-Norman word sulfre. This word was derived from the Late Latin word sulfur changing to Old French soulfre.

Production & Use

Sources

It is found in pure form and in ores such as cinnabar, galena, sphalerite and stibnite. Its pure form is obtained from underground deposits with the help of the Frasch process.

Uses

It is used in the production of matches, gunpowder, rubber, paint, medical and agricultural drugs. It is also used in the production of sulfuric acid (H2SO4).
