Can you see what’s wrong with these sentences?

  • For all intensive purposes, this laptop is useless.
  • I don’t want nothing from you.
  • There’s new people you should meet.
  • Well done (well-done, or well, done,) Tom.
  • I gave him a peace of my mind!
  • I failed that exam. I should of tried harder.
  • I’ll make due with what I have on hand.
  • My wife was angry with me for coming home late. I could care less.
  • I’m listening, Tom. Please precede.
  • I am ready for desert, now.
  • I’m a shoe-in for that promotion.
  • You’re in the wrong que, sir. This is for 10 items or less.
  • Let’s eat Grandma.

If you struggled with some of these, don’t feel bad. Such mistakes are more common than you think. 

The English language has numerous, complicated grammar guidelines, confusing words, and elaborate punctuation rules.

And even first-language speakers confuse verb tenses here and there, use the wrong punctuation, and misspell words.

In fact, it’s safe to say that most of us have misused a word or phrase at one time or another. 

Even Albert Einstein struggled with spelling and grammar.  He reportedly once said, “I cannot write in English because of the treacherous spelling.”

Even when you’re out with friends, the embarrassment of flubbing a word or a verb tense can hurt.

But that’s easy to simply laugh off. 

The real issue is when that mishap happens in a professional context. 

In an age where everyone is constantly communicating, making a silly mistake can hurt how peers, clients, and potential employers perceive you. Such errors can make anyone look foolish—or, worse, unprofessional.

Did you know that punctuation errors, misspellings, and grammatical mistakes can

1

Hinder your chance of making a good impression when meeting someone new, applying for a new job, or landing a new client?

Did you know that 58% of all résumés contain errors? Wait—it gets worse. Some companies, like Google, use résumé-screening software that automatically eliminates résumés containing errors from further consideration.

2

Make your website look unprofessional and spammy, putting off potential readers and clients?

A study discovered that US businesses with bad grammar and spelling mistakes on their websites will lose almost twice as many potential customers as those with typo-free sites.

2

Cause awkward situations or conflicts in the workplace due to misinterpretations—or, worse, full-blown public relationship crises?

Whether in the form of emails, internal newsletters, business reports, white papers, or even company blogs, grammatically incorrect documents can spell disaster for a company when the information presented is false or misleading.

3

Make you look unprofessional and might lead to your being passed over for a promotion?

A study discovered that employees who use good grammar are more likely to succeed at their jobs because their writing and speech will reflect a “level of professional competency” that employers and clients will notice.

It’s better to err on the side of grammar and vocabulary caution because in this digital age, when we communicate increasingly in written texts, emails, and posts, our words are often all we have to make a good impression. 

So, how do you make sure your communication is clear of errors and misinterpretation?

We’ve done some of the hard work for you . . .

Upgrade your grammar, vocabulary, and punctuation skills before the self-appointed grammar police point out your errors—or worse.

Throughout history, a typo or a misinterpretation has more than once spelled disaster. 

And I’m not talking about unfortunate tattoo misspellings. 

A misplaced comma canceled a $760,000 contract.

One of the biggest cases battled over a comma was a dispute between two Canadian telecommunications companies. Rogers Communications and Bell Aliant fought a legal battle worth $760,000 over a contract to replace utility poles across the country. And it all started with a little comma placed after the reference to the duration of the contract.

And in one extreme example, a misplaced comma was at the heart of a death-penalty trial.

Back in 1916, Roger Casement, an Irish nationalist, was found guilty under the 1351 Treason Act of inciting to acts of treason. To his detriment, the wording of this fourteenth-century law and the use of a comma made the difference between life and death.

Unfortunately, examples don’t stop here. 

Fortunately, you have an opportunity to learn how to use language correctly and scrub your sentences of potential errors. 

 

Appearing confident in your writing is easy when your message is mistake-free.

By learning the rules of grammar, spelling, and punctuation, you can write and communicate with better clarity and more confidence, knowing that your message came across as you intended it in the first place. 

In the English-Proficiency Exercise Vault, we guide you through the most common mistakes in American English. Each lesson comes with a downloadable PDF complete with explanations and examples that help build your English skills and improve your writing.

The English-Proficiency Exercise Vault is brought to you by Grammarist.

We help over a million users per month.

We are a team of USA Today best-selling authors, award-winning writers, dedicated English teachers, TEFL-certified educators, and professional proofreaders and editors.

While we love to teach writers, ESL learners, and anyone just looking for grammar and spelling tips, we’re not grammar snobs, and we don’t put things in boxes here, although we do love a good grammar pun every now and then.

How do you comfort a grammar snob?
“There, their, they’re.”

Proper grammar, usage, style, and even definitions are always open to different approaches.

We believe that the English language can and most definitely should always be evolving to meet the communication needs of the world. 

Most aspects of English are governed not by rules but by conventions that are constantly in flux, and we try our best to make sure we stay on top of these changing trends so you, our student, can benefit from this wealth of knowledge.

Good grammar and clear sentences are more than just stylistic preferences—they’re essential to projecting your intelligence, your thoughtfulness, and even your organizational skills.

But too often, even the most capable individuals find their credibility undermined by poorly structured sentences, grammatical oversights, or vague vocabulary. 

This doesn’t just lead to miscommunication; it can paint an unflattering picture of your abilities and intentions, suggesting a lack of respect for your audience or the task at hand.

That’s where the English-Proficiency Exercise Vault comes in as your guide to writing well and sounding professional

Grammarist Mockups Tripwire page blue grey 1

Designed as a complete guide to writing well and sounding professional, this collection will help you avoid the common pitfalls that often compromise communication, such as the following:

Double negatives are a big no-no

It wasn’t until the eighteenth century that the double negative was declared a no-no on the grounds that one negative cancels out the other, and it acquired a reputation for being illogical. 

So, if you want to be taken seriously when you communicate a negative, avoid the double negative at all costs. We teach you how in the English-Proficiency Exercise Vault.

The passive voice is to be avoided. But why?

Tradition has favored the passive voice for writing research papers because it emphasizes the research, not the researcher (though that convention is evolving). Outside of research writing, however, does it even matter?

The answer is yes: Avoid using the passive voice in a business or professional setting. It’s simply too wordy, lacks clarity, and evades responsibility. But how do you transform passive voice into active voice?

We teach you all that and more in the English-Proficiency Exercise Vault.

The past, present, and future walked into a bar. It was tense.

Pun aside, English is riddled with words that don’t like to fit into simple rules. Enter verb tenses—even first-language speakers mix them up at times. But it sounds more complicated than it is in practice. The English-Proficiency Exercise Vault clears the air and teaches you an easy way to learn the verb tenses without risking common errors. 

It’s easy for little mistakes to slip by, especially when you’re self-editing.

So, how do you make sure your emails, texts, and reports are error-free? Professional proofreaders have a checklist system to ensure that a text is flawless before submitting it or publishing it. 

You’ll learn a simple but very effective system to review your texts and edit out the potential mistakes.

As you work through these guides, you’ll learn to structure your thoughts more effectively, refine your sentences for maximum impact, and consistently apply correct grammar.

The result?

You’ll not only sound more professional and respectful, but you’ll also convey your ideas in a way that truly reflects your intelligence and thoughtfulness.

If you’re still thinking . . .

Is there any point in actually learning all of this?

Isn’t this a waste of time, since we already have grammar checkers and spell checkers to correct our texts?

The reality is that grammar checkers and spell checkers are simply not good enough.

Sure, they are immensely useful, but they shouldn’t be a means to an end.

To begin with, these tools don’t catch all the issues:

  • Homonyms (like there and their) are not detected.
  • Proper nouns are often overlooked.
  • They can’t process complex sentences.
  • Automated suggestions can change the meaning of your text.

Such tools should be used only as complementary instruments to your writing, editing, and proofreading process.

So, do not rely blindly on what they are telling you.

Instead, use the English-Proficiency Exercise Vault to upgrade your grammar, vocabulary, and punctuation so you’ll never risk sounding unprofessional again.
