What is an uncountable mass noun?
Uncountable mass nouns are nouns that don't have different plural forms. The easiest way to tell is to use the term in the following sentences:
- "The [enter term]"
- "All [enter term]"
If the term does not change in either sentence then it is an uncountable mass noun.
Even though the plural and singular are the same, the UCF still maps the plural and plural possessive forms.
