Who Uses vs. Who Use – Which is Correct?
“Who uses” and “who use” can both be correct. Use “who uses” when who refers to one person or another singular subject: “Who uses this app?” Use “who use” when who refers to multiple people or a plural noun: “Who use these tools?” The verb agrees with the implied subject.
Who Uses or Who Use – Which is Correct?
Both “who uses” and “who use” are correct, but they agree with different subjects. Use “who uses” when the implied subject is one person or another singular noun. Use “who use” when the implied subject is multiple people or a plural noun.
For example, “Who uses this computer?” asks about one person at a time or an unspecified singular user. “Who use these computers?” asks about several people. In a relative clause, the same rule applies: “She is the person who uses the software,” but “They are the employees who use the software.”
The Best Trick to Remember the Difference
Identify the noun that who represents, then replace who with he or they. If he uses sounds right, choose who uses. If they use sounds right, choose who use.
Use the swap test: “Who uses the printer?” becomes “He uses the printer.” “Who use the printers?” becomes “They use the printers.” Remember that uses has the singular -s ending, while use is used with plural subjects.
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| who uses | Interrogative or relative pronoun + verb | Refers to one person who uses something | Who uses this account? |
| who use | Interrogative or relative pronoun + verb | Refers to multiple people who use something | Who use these facilities? |
How to Use “Who Uses”
Use “who uses” when who refers to one person or a singular noun. The word uses is the third-person singular present-tense form of the verb use. This construction is common in questions, relative clauses, surveys, instructions, and formal writing.
Although who does not visibly show whether it is singular or plural, the verb provides the grammatical clue. If the implied subject could be replaced with he, she, or it, use uses.
Example 1: Who uses the conference room after lunch?
Example 2: I need to speak with the employee who uses this workstation.
Example 3: The survey asks who uses public transportation regularly.

- Subject–verb agreement: A verb must agree with its subject in number. Singular subjects take uses, while plural subjects take use.
- Relative clauses: A clause beginning with who can describe a person or group, as in “the manager who uses the system” or “the managers who use the system.”
- Interrogative pronouns: In a question, who asks about a person or people. The following verb reveals whether the intended subject is singular or plural.
- Third-person singular verbs: In the present tense, many English verbs add -s with he, she, or it: “she uses,” “he works,” and “it helps.”
Examples from Media and Literature
The distinction appears naturally in questions and descriptions involving users, characters, audiences, and groups. The following examples demonstrate the grammar in recognizable media and literary contexts:
- Science-fiction films: “Who uses the Force?” refers to one individual at a time, so uses agrees with the singular implied subject.
- Technology news: “Who uses social media most frequently?” asks about an individual respondent or demographic participant.
- Classic literature: “The character who uses deception to reach the goal” uses uses because character is singular.
- Documentaries: “The communities who use renewable energy” takes use because communities is plural.
- Workplace writing: “Employees who use company equipment must follow safety procedures” uses use because employees is plural.

Frequently Asked Questions
Question 1: Is it “Who uses” or “who use”?
Both are correct. Use “who uses” for one person or a singular subject, and “who use” for multiple people or a plural subject.
Question 2: Is “Who use this product?” grammatically correct?
Yes, when the question refers to multiple people. A clearer version would be “Which people use this product?” If the question refers to one person, write “Who uses this product?”
Question 3: Should I write “the people who uses” or “the people who use”?
Write “the people who use.” The noun people is plural, so it requires the plural verb use. By contrast, write “the person who uses.”
Question 4: Does “who” always take a singular verb?
No. The verb agrees with the subject that who represents. Use uses for a singular subject and use for a plural subject.
Conclusion
“Who uses” and “who use” are both correct forms. Choose uses when who refers to one person, and choose use when it refers to several people. The simplest test is to replace who with he or they: “he uses” requires who uses, while “they use” requires who use. Pro Tip: Correct subject–verb agreement strengthens your credibility in professional emails, reports, applications, and other formal writing.
