Explain the common errors in subject-verb agreement in academic writing.

The common errors in subject-verb agreement in academic writing include:

1. Singular subject with a plural verb: This error occurs when a singular subject is incorrectly paired with a plural verb. For example, "The group of students were studying" should be "The group of students was studying."

2. Plural subject with a singular verb: This error happens when a plural subject is incorrectly matched with a singular verb. For instance, "The books is on the shelf" should be "The books are on the shelf."

3. Indefinite pronouns: Indefinite pronouns, such as "everyone," "someone," or "nobody," are singular and should be paired with singular verbs. For example, "Everyone have their own opinions" should be "Everyone has their own opinions."

4. Collective nouns: Collective nouns, like "team," "committee," or "family," can be singular or plural depending on the context. When referring to the group as a whole, a singular verb should be used. For instance, "The team is playing well" is correct, while "The team are playing well" is incorrect.

5. Intervening phrases: When there are phrases or clauses between the subject and verb, it is important to ensure that the verb agrees with the subject, not the intervening words. For example, "The book, along with the pen, were on the table" should be "The book, along with the pen, was on the table."

6. Compound subjects: When two or more subjects are joined by "and," the verb should be plural. For instance, "John and Mary is going to the party" should be "John and Mary are going to the party."

7. Titles, names, and expressions: Titles, names, and expressions that are treated as singular should be paired with singular verbs. For example, "The United Nations is an international organization" is correct, while "The United Nations are an international organization" is incorrect.

It is important to pay attention to subject-verb agreement in academic writing to ensure clarity and accuracy in conveying ideas.
