A mass noun refers to something that can’t usually be counted. In fact, it’s sometimes called an uncountable or noncount noun. It’s not to be confused with collective nouns! In this post, we’ll explain the rules that apply when you use mass nouns in your writing.
Mass nouns usually belong to one of the following groups:
● Liquids and gasses
● Materials that consist of tiny pieces
● Weather
● Feelings and qualities
● Collective terms
Even though mass nouns often refer to a large quantity of something (e.g., sand), they’re always used with singular verb forms:

If you want to indicate how much of a mass noun you’re referring to, you can place a unit of measurement or another suitable describing word in front of it:
Some nouns have countable and uncountable (mass) forms. For example, “cheese” is usually a mass noun, but if you’re referring to varieties of cheese, it becomes a countable noun:
Another example is “language,” which is a mass noun when you’re referring to the idea or concept of language, but a countable noun when you’re talking about a particular language:
Mass (or uncountable) nouns are things that can’t be easily counted. If you’re not sure whether a noun is countable or not, try putting a number in front of it and adding “s” (or “es”) to the end. If it doesn’t sound right, then it’s probably a mass noun. For example, you wouldn’t say “five traffics” or “100 courages,” so “traffic” and “courage” are mass nouns.
As we’ve seen though, this rule isn’t completely reliable, as some words, like “cheese” and “language,” can be both mass and countable nouns.
