What does matter mean?
Matter is a versatile word that can refer to the physical substance of an object, the subject of discussion, or something of genuine importance.

Where does matter come from?
The word entered Middle English through Old French matere, which came from Latin materia, meaning "material" or "stuff." The Latin word developed in the context of materials and the substance from which things are made. English later extended the word to mean an issue or affair, while the meaning "be important" developed from the older sense of substance and consequence.
