Common Grammar and Punctuation Mistakes

Understanding grammar and punctuation is crucial for clear and effective writing. However, even seasoned writers can slip up. Here are some common mistakes and tips on how to avoid them:

• Comma Splices: A comma splice occurs when two independent clauses are incorrectly joined by a comma. To fix this, you can use a semicolon, a conjunction, or split the clauses into separate sentences. For example:

  • Incorrect: I went to the store, I bought some bread.

  • Correct: I went to the store, and I bought some bread.

• Misplaced Apostrophes: Apostrophes are often misplaced in possessive forms or contractions. Remember, use apostrophes to show possession (e.g., John’s book) or to form contractions (e.g., don’t for do not), not to pluralize words.

• Incorrect Use of Semicolons: Semicolons are often misused. They should connect two related independent clauses or separate items in a complex list. For example:

  • Correct: She has a big dog; it’s a German Shepherd.
