What are the common errors in subject-verb agreement and how can they be resolved?

Subject-verb agreement errors occur when the subject and verb in a sentence do not agree in terms of number (singular or plural). These errors can be resolved by following a few key rules.

1. Singular subjects require singular verbs, while plural subjects require plural verbs. For example:
- Incorrect: The dog's barks loudly. (subject: dog, verb: barks)
- Correct: The dog barks loudly.

2. When a sentence contains compound subjects joined by "and," the verb should be plural. For example:
- Incorrect: The cat and the dog is playing in the yard. (subject: cat and dog, verb: is playing)
- Correct: The cat and the dog are playing in the yard.

3. When a sentence contains compound subjects joined by "or" or "nor," the verb agrees with the subject closest to it. For example:
- Incorrect: Neither the cat nor the dogs likes to swim. (subject: cat and dogs, verb: likes)
- Correct: Neither the cat nor the dogs like to swim.

4. Indefinite pronouns, such as "everyone," "someone," or "each," are singular and require singular verbs. For example:
- Incorrect: Everyone were excited about the party. (subject: everyone, verb: were)
- Correct: Everyone was excited about the party.

5. Collective nouns, such as "team," "family," or "group," can be singular or plural depending on the context. If the members of the group are acting as individuals, use a plural verb. If the group is acting as a single unit, use a singular verb. For example:
- Incorrect: The team were celebrating their victory. (subject: team, verb: were celebrating)
- Correct: The team was celebrating its victory.

6. When a sentence begins with "there" or "here," the subject follows the verb. The verb should agree with the subject, not the word "there" or "here." For example:
- Incorrect: There is many books on the shelf. (subject: books, verb: is)
- Correct: There are many books on the shelf.

To resolve subject-verb agreement errors, it is important to identify the subject and verb in a sentence and ensure they agree in terms of number. Pay attention to the rules mentioned above and practice using them correctly. Additionally, proofreading and editing your writing can help identify and correct any errors in subject-verb agreement.
