13 Best Sites to Practice English Grammar Online (for Free)


If you’re looking for the best sites to practice English grammar online, I’ve got you covered. With so many sites in cyberspace, how do you know which ones are best for you?

As a trained proofreader and someone qualified to teach English as a second language, I know a good grammar site when I see one.

I’ve spent many hours researching websites to bring you the best ones, and I’ve organized them according to the grammar proficiency levels they cater to.

Whether you’re a beginner ELL (English language learner) or a native English speaker who’s soon to be a grammar guru, this article has recommendations for you.

I’ll tell you what each site offers and what I like most about it.

At the end of this article, I’ll leave you with some helpful tips to make learning grammar as simple as possible.

Note: If you’re a high school or college student, my article about the best grammar sites for university students will better meet your needs.

Website Winners (My Number One Picks)

Here are my top picks for the best websites to learn grammar according to various levels. Since my site caters to aspiring proofreaders, I’ve included my top choice for those wishing to work on error patrol. 😉

Best Site Overall (suitable for ELLs and native English speakers): Grammar Monster

Best for ELLs of All Levels: British Council LearnEnglish

Best for Beginner ELLs: EnglishClub

Best for ELLs Preparing for an English Language Exam: Exam English

Best for Native English Speakers: GrammarBook.com

Best for College Students: University of Bristol (Grammar and Punctuation)

Best for Aspiring Proofreaders: CMOS Shop Talk

Criteria for Websites

To be included in this post, a site had to meet the following criteria:

  • be a reputable site with accurate information
  • have exercises, quizzes, tests, or some way to practice English grammar
  • be easy to navigate
  • have grammar content available for free
  • not require registration to access the content

How These Sites Are Organized

I’ve organized these sites according to their suitability for various levels of grammar learners.

Three websites are suitable for several levels, so I’ve listed those sites first.

Then, they’re in order starting with sites for ELLs and ending with sites for advanced learners.

How I Define the Levels

Here’s what each level means:

ELL: You’re learning English as a second language.

Beginner: English is your first language, and you have a below-average understanding of grammar (e.g., you’ve forgotten most of what you learned about grammar in middle and high school). If this is you, don’t worry! It was me at one point. 😊

Intermediate: English is your first language, and your grammar knowledge is on par with most people.

Advanced: English is your first language, and you have an above-average understanding of grammar (e.g., you remember much more than most from your grammar-learning days or are currently in high school or college).  

Who Can Benefit from These Sites?

The following people can benefit from these websites:

  • English language learners
  • students of all levels
  • job seekers
  • professionals in all fields (especially the publishing industry!)
  • proofreaders and aspiring proofreaders

If you’re an English language learner, you’ll benefit from the simple explanations and practice activities on these websites. Using these resources will speed up your acquisition of English.

As a student, you’ll benefit because getting a leg up on your grammar game translates into better grades on written assignments.

If you’re a job seeker, the grammar in your résumé, CV, or cover letter can mean the difference between getting a job or getting overlooked.

As for professionals in the working world, good grammar will help you gain trust and maintain your authority. Bad grammar can undermine your credibility and make you look careless and unprofessional. Yikes!

Finally, for all you proofreaders, the more grammar you know off the top of your head, the more efficient you’ll be on the job! And the more efficient you are, the more money you can make.

1) Grammar Monster


Grammar Monster has been one of my favorite sites for years. Why? It’s a ton of fun! If you have any reservations about learning grammar, hop on over to this site.

Despite the name, I promise it won’t scare you. 😉 On this website, learning grammar becomes more like a fun game and less like a tedious bore of a chore.

Grammar Monster does an exceptional job of incorporating infographics into its content. And who doesn’t love a well-designed infographic to make concepts easier to understand?

Grammar Monster has also spruced up its site design. Looking good, Grammar Monster!

But what I like the most is the form that invites you to tell Grammar Monster the words you plan to use for a tattoo you’re getting.

These zones are in addition to the activities for practicing all four language learning skills.

If you select the correct answer, you win a cool cyber prize. And when you choose the wrong answer, you get a prize—but it’s nothing you would hope for. 😉

The interactive exercises include sound effects, so make sure you turn up the volume. The sounds for some of the incorrect answers made me laugh out loud.

Robin has a great sense of humor!

13) CMOS Shop Talk

5 Tips for Learning Grammar Easily

Here are a few tried-and-true tips for getting the most out of these grammar websites.

1) Study a little bit each day.

Consistency is the key. Studying for a short time each day will improve your retention of the material and prevent burnout.

2) Build a solid foundation.

Lots of grammar concepts build on one another, so make sure to master basic concepts before trying to grapple with more advanced ideas.

For example, identifying direct and indirect objects won’t be possible until you understand how to locate subjects and verbs.

3) Keep a dedicated notebook to practice English grammar.

Putting things in writing helps to reinforce what you’re learning. You can also jot down any questions you have while studying.

You can try to find answers to your questions on these grammar sites (sometimes through forums).

If you can’t find your answer on these sites, Google, Quora, and Reddit are good sources to consult.

4) Use a variety of mediums for learning grammar.

Learning through a variety of mediums helps keep things interesting.

Reading lessons, watching videos, listening to audio transcripts, responding to writing prompts, playing games, and taking quizzes and tests are all great ways to boost your grammar game.

Taking advantage of different forms of learning means you’ll be taking in information visually, auditorily, and through reading and writing.

The more senses you involve, the better your retention will be.

And if you know your learning style, you can focus on the types of content that work best for you!

5) Use tests and quizzes to assess your progress.

The sites on this list are chock-full of engaging tests and quizzes. Taking them is a fun way to know what you understand and where you need more practice.

I wrote an article about advice for improving your grammar if you’d like some other solid strategies.

I hope this article highlighting the best places to practice English grammar online helps you immensely.

Best wishes to you!
