Lynne Truss's book is excellent. It's funny, at times, but she explains clearly how to use these marks of punctuation.

In addition, here are a couple of well done webpages to explain how to use these:

To minimize errors when using commas and apostrophes in your writing, here are some tips:

1. Review grammar rules: Familiarize yourself with the basic rules of comma and apostrophe usage. There are numerous online resources and grammar books available that can help you understand these rules.

2. Study examples: Look for well-written texts, such as books, articles, or academic papers, and pay attention to how commas and apostrophes are used throughout. Analyzing examples can help you get a sense of proper usage in different contexts.

3. Proofread your work: Always proofread your writing before submitting it. Read your sentences aloud, which can help you identify if a comma or apostrophe is needed or if something sounds off. Reading backwards, sentence by sentence, can help you focus on individual punctuation marks.

4. Use grammar check tools: Utilize grammar and spell-checking tools available in word processors, such as Microsoft Word or Google Docs. These tools can identify some comma and apostrophe errors, but remember that they are not perfect and may not catch all mistakes.

5. Seek feedback: Ask a trusted friend, colleague, or teacher to review your work and provide feedback on your comma and apostrophe usage. Their fresh perspective can help you spot errors that you might have missed.

6. Practice regularly: The more you write, the better you will become at using commas and apostrophes correctly. Practice writing sentences that require the use of these punctuation marks, and ask someone to review your work or compare it with trusted grammar resources.

Remember, mastering comma and apostrophe usage takes time and practice. The key is to be consistent, pay attention to context, and keep improving your skills through continual learning and application.
