Subject-verb agreement is a crucial component of grammar. The subject of a sentence refers to the person or thing that is performing an action or being described, while the verb is the action or state of being that the subject is involved in. In order for a sentence to be grammatically correct, the subject and the verb must agree in number and person.

For instance, if the subject is singular, the verb must also be singular. Likewise, if the subject is plural, the verb must also be plural. For example, “She eats a sandwich” is correct because the subject (she) is singular and the verb (eats) agrees with it. On the other hand, “She eat a sandwich” is incorrect because the verb (eat) is plural, while the subject (she) is singular.

Similarly, subject-verb agreement also applies to the tense of the sentence. If the subject is in the present tense, the verb must also be in the present tense. If the subject is in the past tense, the verb must also be in the past tense. For example, “He runs every day” is correct because both the subject (he) and the verb (runs) are in the present tense. Meanwhile, “He run every day” is incorrect because the verb (run) is in the past tense, while the subject (he) is in the present tense.

In conclusion, subject-verb agreement is an integral part of grammar that every writer and editor should be familiar with. It helps ensure clarity and coherence in writing, making it easier for readers to understand the intended message. As an SEO copy editor, it’s essential to be mindful of subject-verb agreement when creating content. A well-written article that adheres to proper grammar rules not only impresses readers but also increases the chances of ranking higher in search engine results.
