English grammar can be a complicated subject, even for born speakers. With its complex rules and exceptions, it's easy to get tripped up and make mistakes. However, being aware of common errors can help you improve your writing and speaking skills. In this article, we'll go over some common mistakes in English grammar and provide tips on how to prevent them.

One of the most common mistakes in English grammar is subject-verb agreement. This occurs when the subject of a sentence and the verb do not match in count. For example, "The team are going to the championship" is incorrect because "team" is a single entity and should be followed by a singular verb. To avoid this mistake, make sure to match your subject and verb in count.

Another common mistake is the use of the wrong form of "who" and "whom." "Who" is used as the subject of a sentence, while "whom" is used as the object. For example, "Who did you see at the party" is correct, while "Whom did you see at the party" is incorrect because "whom" implies that the person being seen is the recipient. To avoid this mistake, try to use "who" when the person being discussed is the main character, and use "whom" when the person is the recipient.

Tenses are also a common source of error in English grammar. The three main tenses - previous, current, and upcoming - can be tricky to navigate, especially in complex sentences. For example, "I go to the store yesterday" is incorrect because the verb "go" should be in the past tense to match the previous tense subject "I." To avoid this mistake, try to use the correct tense for the verb and main character.

The misuse of the apostrophe is another common mistake in English grammar. Apostrophes are used to indicate ownership or to form contractions. For example, "its" is used to show ownership, while "it's" is used as a contraction of "it is." To avoid this mistake, try to use the apostrophe correctly to indicate ownership or to form contractions.

By being aware of these common errors, you can improve your writing and speaking skills and avoid making mistakes that might mislead or deceive your audience.
