Here's how to break down the name:

* Mn represents the element Manganese.

* (III) indicates that Manganese has a +3 oxidation state.

* SO₄ represents the Sulfate ion (SO₄²⁻).

* 3 indicates that there are three Sulfate ions in the compound.

It's important to note that the Roman numeral (III) is necessary because Manganese can form multiple ions with different charges.
