As a copy editor who specialises in search engine optimisation (SEO), one of the most common errors I come across is the incorrect use of has and have in subject-verb agreement. While it may seem like a trivial mistake, it can seriously affect your website`s search engine ranking and overall credibility. In this article, I`ll explain the basics of subject-verb agreement using has and have and provide some tips on how to avoid this common error.
Subject-Verb Agreement Using Has and Have
The basic rule of subject-verb agreement is that the verb should agree with the subject in number (singular or plural). This means that if the subject is singular, the verb should be singular too, and vice versa. However, when it comes to has and have, things can get a bit more complicated.
Has is the third-person singular form of the verb to have, while have is the first and second-person singular and all-person plural form of the verb. For example:
– She has a car.
– I have a car.
– They have a car.
When using has and have in subject-verb agreement, it`s important to remember that has is always used with singular subjects, while have is always used with plural subjects. For example:
– The cat has a mouse.
– The cats have mice.
The above examples show that has is used with a singular subject (cat) and have is used with a plural subject (cats).
Common Errors in Subject-Verb Agreement Using Has and Have
One of the most common errors in subject-verb agreement using has and have is when the subject and verb do not agree in number. For example:
– The group of students has different opinions. (incorrect)
– The group of students have different opinions. (correct)
In the above example, the subject is group, which is singular, but the verb used is has, which is incorrect. The correct verb to use with a singular subject here is have.
Another common error is when the subject is a collective noun, which refers to a group of people or things, but is treated as singular. For example:
– The team has won the game. (correct)
– The team have won the game. (incorrect)
In the above example, the subject is team, which is a collective noun, but is treated as singular. Therefore, the correct verb to use is has.
Tips for Avoiding Errors in Subject-Verb Agreement Using Has and Have
To avoid errors in subject-verb agreement using has and have, here are some tips to keep in mind:
1. Identify the subject of the sentence: Before choosing the correct verb, it`s important to identify the subject of the sentence and determine whether it`s singular or plural.
2. Use has with singular subjects: If the subject of the sentence is singular, use has as the verb.
3. Use have with plural subjects: If the subject of the sentence is plural, use have as the verb.
