Common Mistakes in English Grammar

English grammar can be a tricky subject, even for native speakers. There are many rules and exceptions to remember, which can lead to common mistakes. In this article, we will explore some of these errors and how to avoid them.

Subject-Verb Agreement

One common mistake is incorrect subject-verb agreement. This occurs when the subject and verb do not match in number (singular or plural). For example:

  • Incorrect: The group of students was excited about the trip.
  • Correct: The group of students were excited about the trip.

It is important to remember that the verb should agree with the subject, even if there are words in between.

Using "Who" and "Whom"

Another common mistake is confusing the use of "who" and "whom." These pronouns are often interchanged, but they have different roles in a sentence. "Who" is used as a subject, while "whom" is used as an object. For example:

  • Incorrect: Who did you invite to the party?
  • Correct: Whom did you invite to the party?

To determine whether to use "who" or "whom," you can rephrase the sentence and see if it fits:

  • Who/Whom did you invite? (You invited him/her) - Correct: Whom
  • Who/Whom is going to the party? (He/She is going) - Correct: Who

Using Incorrect Verb Forms

Using incorrect verb forms is another common error that can be easily avoided. This includes using the wrong tense or not conjugating the verb correctly.

  • Incorrect: He have a lot of books.
  • Correct: He has a lot of books.

It is essential to pay attention to the proper verb form based on the subject and the tense of the sentence.
