Banish confusion

when you choose the right words

An online course by Mary Morel.

This course is part of the larger Business Writing course. After completing this course, you can easily upgrade to the full course.

We all have words that trip us up. I always have to stop and think about the difference between compliment and complement, and I know a lot of people aren't sure about when to use affect or effect.

What words confuse you?

In this self-paced, online course, you'll not only learn the difference between commonly confused words, but will also receive memory jogs for some words to help you remember the differences.

You'll learn from reading text, watching videos and doing quizzes.


What you'll learn

Definitions, memory tips and more

  • Top five commonly confused words

    In my opinion, the top five most commonly confused words are

  • Homonyms

    Homonyms are words that look or sound alike so often cause confusion.

  • A-Z of 100 commonly confused words

    If the words that bother you the most aren't in the top five or the homonym section, don't worry, you'll find them in the A-Z of commonly confused words.

    And if they're not in that section, you can always contact me and I'll add your words to the course.

Mary Morel

Your instructor

I have been working with words all my career as a freelance writer, editor and trainer.

During my career, I've taught thousands of people from a range of organisations, including large corporations, government departments, associations and not-for-profits.

This course is based on my practical experience writing and teaching. I'm always thinking about what works and why in business writing and have developed simple and practical techniques to help you improve your writing.

I believe people who teach writing need to write themselves. I blog regularly and have written three nonfiction books (Promote Your Business, Talk Up Your Business, Write to Govern.)

My qualifications include a BA in English and History, a Diploma of Social Work and a Diploma of Teaching. I am a lifelong student of writing and grammar.


  • Does the price include Australian GST?

    The price is in Australian dollars and includes goods and services tax (GST). If you are an international buyer, contact me and I will refund the GST.

  • How long will this course take?

    I estimate this course will take 9-12 hours, but I recommend that you do it in several sittings, not all at once. The course is broken into sections to make it easy to dip in and out of.

  • How long do I have access to the course for?

    You have 'lifetime' access. In other words, the course does not have an expiry date. You can repeat the course as many times as you like.

  • My writing skills are quite good. Will I learn anything new from this course?

    Definitely. We never stop learning about writing. This is a chance to take your writing to the next level.

  • Will the course be relevant for my industry?

    The principles of good writing apply to all industries.

  • Do you have a money-back guarantee?

    Yes, I have a 7-day money-back guarantee. No questions asked.

  • Will I receive a certificate at the end?

    Yes, you will receive a certificate of completion.
