What does manganese mean?
Manganese is a chemical element and a transition metal known for its role in making steel stronger, harder, and more resistant to wear. It occurs naturally in several ores and can also be found in trace amounts in soil, water, plants, and animals, where it serves as an essential nutrient. In industry, manganese is an important alloying element: adding it to steel helps improve the metal’s strength, toughness, and resistance to high temperatures. Compounds of manganese are used in batteries, pigments, and other chemical products. The element has the symbol Mn and the atomic number 25. Although the word is relatively uncommon in everyday speech, it is well known in discussions of metallurgy, mining, chemistry, and biology. It should not be confused with magnesium, which is a different chemical element with the symbol Mg.
nounManganese is a hard, silvery-grey chemical element belonging to the transition metals. It occurs in various ores and is used principally in the production of steel, where it improves strength and resistance to wear.
- A chemical element, symbol Mn, atomic number 25, that is a hard, silvery-grey transition metal used especially in steelmaking and batteries.
"The bridge is made from steel containing manganese to increase its durability."
"Manganese is added to steel during the manufacturing process to improve its strength."
"The laboratory tested the water for manganese and other metals."
The plural is rare; the element is normally treated as an uncountable noun.
"The samples contained unusually high levels of manganeses from different geological sources."
A few small amounts of manganese can make steel dramatically tougher, helping the metal survive impacts that would damage ordinary steel.

Where does manganese come from?
The English word manganese comes through French from the German Mangan, whose ultimate source is the ancient Greek word mangānōn, probably connected with Magnesia. The name reflects the historical association of the metal with deposits in the region of Magnesia. English use dates to the 18th century, initially in mineralogical and chemical contexts, and later expanded through the development of metallurgy and the naming of manganese compounds.
