- Number of: Refers to a specific quantity of something. It is generally used with singular nouns.
- Numbers of: Refers to multiple quantities or sets of something. It is used with plural nouns.
Initial Context
People often get confused between these two phrases because they sound similar but serve different grammatical purposes. Understanding when to use each phrase can significantly improve the clarity of your writing.
Detailed Analysis of “Number of”
Primary Usage

Examples
- Correct Usage: The number of participants is increasing.
- Incorrect Usage: The number of participants are increasing.
In this example, “number of participants” is treated as a singular subject, thus requiring the singular verb “is.”
Grammar Nuances
When using “number of,” the focus is on the total quantity rather than the individual elements. Therefore, it pairs with singular verbs even though it might involve a plural noun.
Exploring “Numbers of” in Context
Specific Contexts
The phrase “numbers of” is used to describe multiple sets or categories of items. It is usually followed by a plural noun and a plural verb.
Examples
