What are Mass Nouns? (Mass Nouns vs Collective Nouns)
Mass nouns, also non-count nouns, are things or concepts that we cannot physically count. Think fire, sand and water, which are things we cannot count.
mass nouns
Mass nouns mention abstract concepts (e.g., wisdom or justice) or things that exist in forms that cannot be counted, such as masses or substances like sand, rice or gold.
Because of their inability to be counted, mass nouns stay singular in form; (which is why we also refer to them as singular-only nouns). Despite that these nouns are sometimes abundant, they nevertheless differ from things or objects we can easily quantify, and therefore use singular and plural noun forms; such as goose and geese, or child/children.
