Even experienced writers can fall prey to common grammar mistakes. Here are some to watch out for:

  1. Their/There/They're confusion: These words have different meanings and uses.
  2. Your/You're mix-up: 'Your' is possessive, while 'you're' is a contraction of 'you are'.
  3. Its/It's misuse: 'Its' is possessive, 'it's' means 'it is' or 'it has'.
  4. Run-on sentences: Avoid joining independent clauses without proper punctuation.
  5. Misplaced modifiers: Ensure modifiers are close to the words they're modifying.

Being aware of these common mistakes can help you avoid them in your writing.
