Is It OK to Use Conversational Phrases in Formal English Writing?

Improve Spoken English

I got a comment on my blog post Sometimes It Makes More Sense to Acquire English Vocab as Part of Figurative Speech from Binh Thanh asking the following question: “Can we use these phrases in formal writing?”

Now, for those who’re not familiar with the concept of idiomatic expressions and English collocations, here’s a very brief intro:

  • English language actually consists mostly of word GROUPS;
  • Phrases, expressions and idioms (otherwise known as collocations) form a big part of those word groups;
  • If you learn new English vocab as part of every-day expressions and idiomatic language, you’re so much more likely to speak fluently!

Now, Binh Thanh’s comment highlights a very long-standing myth, namely -formal, written English is a completely different beast altogether, and when you write formal correspondence or reports, for example, you have to write in a completely different way you speak.

Personally I call BS on that!

Use ANY Language You Want When Writing – For As Long As It’s Not Slang!

I STRONGLY believe that you can TOTALLY use any idiomatic language used in normal, spoken English (for as long, of course, as you don’t start using slang!) when you write any of the following:

  • Internal company correspondence;
  • Performance reports;
  • Letters and applications;
  • Business plans!


Simply because my experience of reading in English has thought me over the years that something that’s been written following rigid formal English writing rules is VERY HARD TO READ!

Most Successful Communicators Use Friendly, Easy-to-understand Language!

The most successful bloggers and online entrepreneurs communicate with their audience in writing the same way they’d speak.

The most interesting and captivating English fiction books are also written in a very easy-to-read and colloquial way.

Have you ever put a book down onto a library shelf just because you simply couldn’t read more than a couple of paragraphs of it? I have, and the reason has always been the very same – the writing style is so detached from real English that I have to really strain all of my cognitive senses to figure out what the author is trying to say in the book!

The very same goes with any type of written communication – people who understand the effectiveness of simple language, WILL use simple language and figurative, idiomatic language is definitely part of it.

Formal Writing is Oftentimes a Way of Impeding the Perception of the Message

Did you immediately understand the headline above?

Chances are – it took you some time to decipher the meaning of it, and it’s all because I used some fancy words – “to impede” and “perception” – to make it sound more formal.

I could have rephrased the above sentence the following way: “Formal Writing Often Prevents People from Understanding the Message”, and you have to agree that this second sentence is by far easier to understand.

Now, touching upon the actual subject of this sub-section of the article:

I really believe that on many occasions formal language is used to deliberately make the piece of writing hard to understand.

It’s very typical, for example, for various contract terms and conditions be written in a very hard-to-understand way, and I’d say that on 9 times out of 10 people never bother reading them! And it’s not just because those terms are laid out on 10 A4 sheets, it’s all because the legal English used in them is very, very hard to understand.

BOTTOM LINE: Forget About the Concept of Formal Written English!

I’ve been writing articles on my blog for years, and I’ve always used friendly and simple English in them. I even make sure to highlight various idiomatic expressions in read in my articles, and it just goes to show how effective such means of communication are.

Also, just have to look at any tabloid newspaper – they’re all printed using colloquial English and people just love reading such easy-to-perceive content.

It’s just a MYTH that:

  • If you’re an intelligent person, you have to use formal English;
  • Using colloquialisms in your writing you’ll make it sound worse.

This myth clearly stems from a hundred-year-old notion that your language also represents your social class, and the higher up in the social hierarchy you are, the more formal you have to write and speak.

Sure enough, I’m not advising people to start speaking using heavy slang and indecent language; the point I’m making is:

Contemporary people all over the world have realized the importance of writing the way people speak, and using idiomatic language and colloquial expressions in writing is 100% normal!

Any questions?

Feel free to ask! 😉
