Mastering English Grammar: The Dos and Don'ts You Need to Know

1. Subject-verb agreement errors: Always make sure that the subject and verb in a sentence agree in number. For example, "The dog barks" (singular subject, singular verb) vs. "The dogs bark" (plural subject, plural verb).

2. Using the wrong tense: Be consistent with your use of verb tenses. For example, "I walked to the store" (past tense) vs. "I am walking to the store" (present tense).

3. Misusing apostrophes: Use apostrophes to show possession or to indicate a contraction. For example, "That is Sarah's book" (possession) vs. "It's a beautiful day" (contraction of "it is").

4. Confusing homophones: Homophones are words that sound the same but have different meanings. Be careful to use the correct one in your writing. For example, "there" (location) vs. "their" (possession) vs. "they're" (contraction of "they are").

5. Run-on sentences: Avoid sentences that are too long and contain too many ideas. Instead, break them up into smaller sentences.

6. Fragments: A fragment is an incomplete sentence that lacks a subject or verb. Make sure each sentence is complete and can stand alone.

7. Double negatives: Do not use two negative words in the same sentence, as this can create confusion. For example, "I don't have no money" should be "I don't have any money."

These are just a few examples of common grammar errors to avoid. Remember to proofread your writing carefully and use reliable resources to check any grammar rules you are unsure about.
