“Who Has” or “Who Have” – Which Is Correct?

Understanding the proper usage of “who has” and “who have” can greatly enhance your writing and speaking clarity.

This guide will break down the rules for using these phrases, offer practical examples, and provide tips for avoiding common mistakes. 

Let’s dive into this crucial aspect of grammar.

Basic Grammar Rules for Subject-Verb Agreement

Subject-verb agreement is a fundamental grammar rule that ensures subjects and verbs match in number and person. For instance:

• Singular Subjects: Use singular verbs.
  • Example: She writes every day.
• Plural Subjects: Use plural verbs.
  • Example: They write every day.

This rule helps maintain consistency and clarity in writing. The subject and verb must agree to avoid confusion, especially when dealing with pronouns like “who.”

Understanding the Pronoun “Who”

The pronoun “who” serves as a substitute for people or specific entities in a sentence. The choice between “who has” and “who have” depends on whether “who” refers to a singular or plural subject.

• Singular: When “who” refers to one person or entity.
• Plural: When “who” refers to more than one person or entity.

When to Use “Who Has”

Use “who has” when referring to a single person or entity. This follows the rule of subject-verb agreement where the subject is singular.

Examples of “Who Has”

• Example 1:Who has the key to the office?
  • In this sentence, “who” is singular, so “has” is correct.
• Example 2:Who has finished their report?
  • Here, “who” refers to a single person who has completed a task.

Contextual Clues for Using “Who Has”

To decide whether “who” is singular:

1. Identify the Subject: Determine if the “who” refers to a single individual.
2. Check for Singular Actions: Ensure the verb form matches a singular subject.

When to Use “Who Have”

Conversely, use “who have” when referring to multiple people or entities. This follows the rule of subject-verb agreement where the subject is plural.

Examples of “Who Have”

• Example 1:Who have completed the survey?
  • Here, “who” refers to more than one person who has completed a task.
• Example 2:Who have the resources for this project?
  • “Who” refers to multiple individuals possessing resources.

Contextual Clues for Using “Who Have”

To determine if “who” is plural:

1. Identify the Subject: Determine if the “who” refers to more than one individual.
2. Check for Plural Actions: Ensure the verb form matches a plural subject.

Common Mistakes and Misunderstandings

Misuse of “who has” and “who have” often arises from confusion about singular and plural subjects. Here are some common mistakes:

1. Misidentifying the Subject: Incorrectly treating a plural subject as singular.
2. Inconsistent Verb Forms: Using “has” with a plural subject or “have” with a singular subject.

Tips for Avoiding Errors

1. Double-check the Subject: Always verify if “who” is singular or plural.
2. Read Aloud: Hearing your sentence can help spot incorrect verb usage.
3. Practice with Examples: Use exercises and examples to reinforce correct usage.
