Material noun definition: A noun that is used to mention a substance or material from which various other things can be made is called Material Noun. It mainly denotes a material in general instead of a part or individual particle of material. The name ‘Material Noun’ is given to the group because materials such as cloth, air, gold, soap, wood, glass, fiber, etc are included in this class of nouns. https://nebstudent.com/material-noun-definition-examples-and-/rules
