The right word for the right job.

Compliment or complement? Is “enormity” what you really mean? This section helps you choose the correct word to convey your exact meaning. From words that sound or look alike, to words that are often misused or misspelled. Make your communication rise above the crowd. And be confident you’re saying precisely what you mean.


Be sure your meaning is crystal clear.

Punctuation was created more than 500 years ago to make reading easier and keep your meaning clear. In most cases, it’s easy to know what’s right. But sometimes there’s more than one correct style. All those answers are here.


Don’t follow the crowd into these mistakes.

We all know it. English spelling is nothing if not inconsistent. That’s because it has its roots in so many different tongues. But that’s also what makes it such a rich language. Here is where you’ll easily find the correct way to spell the most commonly misspelled words.


The CFO told your CTO that ICT must provide EPS to determine EBITDA. WTF?!?

When everyone around you talks in letters, don’t be left behind. These common abbreviations will let you know what they’re saying. And give you the confidence to speak their language.


When you want to express billions and billions.

Numbers are the language of precision. Add precision to your communication, whether you’re talking about kings or fractions or page numbers.


Your French doesn’t sound so sophisticated if you’re calling a cat
a dog.

One reason English is such a rich language is its generous use of words and phrases taken from other languages. Use the subtle nuances of another tongue to enrich your communication.


We believe that clear communication is the most important part of any business. Since 1975, our team has been writing, rewriting, and editing books, manuscripts, white papers, annual reports, blogs, articles – anything to do with communication.

They say you never get a second chance to make a first impression.
