English mistakes to avoid — or not! Tips from an editor
English mistakes to avoid — or not!
There are some English mistakes to avoid and some you really don’t need to worry about. Sometimes breaking the rules can actually improve your writing. As an editor, there are some mistakes that I see time and time again. But I don’t always correct them; sometimes I even change something ‘correct’ into a ‘mistake’!
English is a rich, complex and beautiful language. But its spelling, punctuation and grammar are not always easy to get right. English has its style guides – which often contradict each other – but no official body determines what’s right or wrong (such as the Académie Française in France, for example). So how can you tell if what you’ve written is correct or not? And when should you care?
What’s right, what’s wrong, and when does it matter?
The purpose of writing is to communicate. Communication works best when people respect spelling, punctuation and grammar conventions.
The idea is that if we follow these rules, using the right words in a standard way to convey a particular meaning, we communicate better.
But correct writing is not only about conveying meaning. You could make countless mistakes and still convey what you mean. Writing also provides all sorts of implicit information such as social cues about the writer. To [over]simplify, if we make spelling, grammar or punctuation mistakes, readers might assume that we are ignorant, stupid, rebellious…
Language mistakes can make our readers doubt our credibility or competence.
A few small mistakes are unlikely to damage your reputation. You might get a free pass if the reader knows English is not your first language. But you can’t always assume they know that, or that they’ll forgive your mistakes. And depending on the when and where, it might have relatively serious consequences.
So here’s my guide to the mistakes you can make, the ones you should try hard to avoid, and the ones that are OK sometimes.
I’ve already discussed some grammar rules that you can break in my article 10 new rules of business writing, so I won’t repeat that here. Check it out for tips about:
- starting sentences with And or But (yes, you can)
- writing paragraphs of just 1 sentence (fine)
- using contractions (it’s fine too)
- ending a sentence with a preposition (no problem)
- splitting infinitives (ditto).
English mistakes to avoid, rules to follow and rules you can break
1. AVOID – Inconsistency. Be consistent, even when the rules aren’t
Whatever style guide you use (or don’t use), be consistent. Many rules of English are a stylistic choice rather than a hard and fast rule — just be inconsistent. But remember, style guides are just guides, not laws.
2. AVOID – Spelling mistakes
English spelling is not difficult to get right: use a dictionary. That’s what they’re for. Google (or any other search engine) is your friend; if you’re offline use a book. Now that we all have smartphones glued to us, you have a dictionary at hand all the time. Isn’t that great?!!
3. AVOID – False friends
Hesitating about similar words? Speciality vs specialty? Alternative vs alternate? Eventually vs finally? A simple Google search will reveal that you’re not the first person to wonder about it and you’ll get plenty of expert advice. Just type in the 2 words you’re comparing like this: ‘word1 vs word2’. If in doubt, try Google Books Ngram Viewer to compare frequency of usage.
4. AVOID – The wrong homophone
Gorilla, guerilla. If you’re using a word that sounds like another word (homophones) make sure you’re using the right one. I mean really make sure: check it. Recently I read a book full of mistakes such as bear-faced lie and a sweet of rooms, not to mention the typos. I paid for that book and felt short-changed.
5. BREAK OR FOLLOW – Formal vs informal language
Follow or break rules about so-called formal language depending on context. Who are you writing for and in what channel or circumstances? Don’t write a WhatsApp message like a formal letter. Don’t write a business report like a Tweet. In a WhatsApp message, you can play fast and loose with language and punctuation. Not so much in a business email…
… But don’t assume that one channel is necessarily informal and another formal. Think of your reader and use your common sense. For example, this excellent article highlights research indicating that, because readers have become more accustomed to incorrect or incomplete punctuation on social media, when we use correct punctuation – in social media or other channels – it can be misinterpreted as hostility or aggression!! The research refers to younger readers, but a quick poll of my middle-aged friends confirms it (now that’s some solid research!). On the other hand, an article in LinkedIn or a Tweet about your newly appointed CEO should be well written and correct, even if the tone of voice is light.
6. BREAK – Rule about ‘who/whom’
I’m not even going to bother to explain when it is ‘correct’ to use whom instead of who. It’s pretentious, snobbish, antiquated and [insert any other synonym for elitist and old-fashioned that you can think of] to use whom. Ever. Just use who and dump all your old whoms on a scrap heap or donate them to a retired English teacher.
7. BREAK – Rules about exclamation marks
Use! Exclamation!! Marks!!! Traditional style guides say that the use of punctuation to indicate tone of voice should be very restrained. We’ve all learned, for example, that you shouldn’t use more than 1 exclamation mark (per page / per email…), and you should never use them in formal communication. It’s said that using exclamation marks (or multiple question marks etc.) makes you appear juvenile, insincere or unprofessional.
Not so true anymore. Many linguists now say that we have become so used to (immune to?) exclamation marks through their frequent use in digital media, that OMITTING them makes the tone of voice harsh or rude. In business emails, for example, a fairly generous scattering of exclamation marks can make the tone more friendly. There’s a world of difference in tone between “I’ll need your report by tomorrow. Thank you!!” and “I’ll need your report by tomorrow. Thank you.”
Obviously, the example Use! Exclamation!! Marks!!! is a joke. Common sense, people!
8. FOLLOW – Rules about hyphens (mostly)
In English you can use a short, medium or long dash. The hyphen (-) is the shortest dash. It’s used in compound nouns that represent a single concept (mother-in-law; x-ray, close-up), and in compound adjectives: an up-to-date manual, a made-to-measure suit.
The most common mistake people make is using hyphens when they are not required, or vice versa. They know they’ve seen up-to-date or made-to-measure with hyphens, but haven’t known or wondered why, and just think “OK, I need to put hyphens in this.” So they write ‘this information is up-to-date’ or ‘this suit is made-to-measure — which is wrong!
The rule of thumb is: if the descriptor comes before the noun, hyphenate. If it comes after, don’t hyphenate.
Here are the rules about hyphens:
- Use hyphens to bring words together when you want to combine their meanings into a single adjective that describes a noun. So you’d put the hyphens in ‘this is up-to-date information / a made-to-measure suit’ because in this case you want to combine up+to+date into a single adjective describing ‘information’ and ‘made+to+measure’ into a single adjective describing the suit. By putting in hyphens, you’ve combined 3 different words into 1 single descriptor, called a compound adjective.
- Don’t put hyphens in word sequences that come after the noun. So you’d write ‘This information is up to date’ because ‘up to date’ simply means it is correct up to [today’s] date. Or ‘This suit is made to measure’ because it is made to the measure of the wearer. No need for hyphens.
- Similarly, you put hyphens in ‘close-up’ because you are combining the 2 words into a single concept. It’s called a compound noun. And in this case, you would always use hyphens when you mean ‘a photo taken at close range’. (Don’t hyphenate the words close+up at other times: I moved over to the wall to look at the portrait close up.)
- Don’t use a hyphen to combine words that can be written as a single word without any risk of misreading or ambiguity, such as email, airline, goldfish…
- Use a hyphen to avoid ambiguity. It’s better to write ‘co-worker’ than ‘coworker’ because that could be read as ‘cow-orker.’ Use a hyphen to distinguish between re-creation and recreation, re-covered and recovered…
- In adverb-adjective modifiers, there is no hyphen when the adverb ends with -ly: locally sourced eggs.
9. BREAK – Rules about hyphens (sometimes)
Don’t use a hyphen if it’s not helpful to the reader. There are many cases where strictly speaking you should have a hyphen but in practice it’s often not used. For example a well designed suit or a well trained dog or a high school student. There is no real ambiguity and the hyphen is just unnecessary ‘noise’ in your text.
10. FOLLOW – Rules about en dashes in dates and numbers
En dashes (–), or ‘short’ dashes, are used to indicate inclusive dates or numbers and can be read as ‘from … to’: March 27–April 4; children aged 5–8; pp. 14–17.
11. FOLLOW – Rules about en or em dashes in sentences
Em dashes (—), or ‘long’ dashes, are used to separate a clause in a sentence or to break off the last part of a sentence from the rest: Dogs — whether long-haired or short-haired — can quickly become over-heated in cars in hot weather; Dogs can quickly become over-heated in cars — especially in hot weather..
In principle, you can use en dashes instead of em dashes – like this – to separate a clause in a sentence.
12. BREAK – Rules about spaces around em dashes
Many style guides state that if en or em dashes are used to separate a clause, there should be no spaces before or after the dash. Some guides say there should be no spaces around an em dash, but spaces around an en dash.
I recommend always using em dashes — with spaces on either side — to separate clauses and to separate the end of a sentence. More and more, we’re reading on screens, not on paper. On a screen, it’s easier to see dashes that are longer and have spaces on either side. Depending on the font, sometimes en dashes look as short as a hyphen, so the clause separation is not immediately obvious if you use an en rather than an em dash.
Moreover, what we read on the screen is often reformatted — according to the size of the screen — so line breaks occur in unexpected places (=responsive design). Using dashes without spaces can push the whole ‘word’ onto the next line, which can cause very odd line breaks if the words are long: In the sentence above, using an em dash without spaces would create the word reformatted—according, which would cause an ugly white space at the end of a line if it were pushed to the next line.
13. FOLLOW – 1 simple rule for punctuating lists
The question is: should you start items in a list with a capital letter or not? And should each item end with a comma (or semicolon) or not?
This is one that many people struggle with because there is no consensus: depending on which style guide you use you’ll see contradictory advice.
I have my own rule. It’s simple to remember and apply every time: if it’s all 1 sentence, don’t capitalize or punctuate items. Otherwise, do.
It’s very clear for a simple list like this: Jack looked in the fridge and saw:
- a carton of eggs
- a stick of butter
- apples, pears and a pineapple
- a dish of leftover lasagna.
If it’s not so obvious, ask yourself if conceivably this list could be written as 1 sentence. For example — Jack thought about what he might eat for breakfast: a cheese omelette with buttered toast, to use up the old eggs; yogurt and a fruit salad; or last night’s leftover lasagna. This could become —
Jack thought about what he might eat for breakfast:
- a cheese omelette with buttered toast, to use up the old eggs
- yogurt and fruit salad, or
- last night’s leftover lasagna.
The easy rule of thumb is, if you introduce a list with a colon, consider the items as part of the same sentence. So don’t use a capital letter. Don’t use punctuation at the end of each item, just a period at the end of the last item. Punctuation is not needed at the end of each item because the items are already separated by the bullet points.
By contrast, if the list consists of items that could not be written as 1 run-on sentence, then capitalize each item normally. For example — Jack thought about what he might eat for breakfast.
- He could make a cheese omelette with buttered toast.
- He might finish with a fruit salad.
- Or eat the leftover lasagna.
14. BREAK – Rules about spelling out numbers
OK, this is my own personal crusade. I know all the rules about when to spell out numbers in text and when to write them as digits. I even know all the contradictions in the rules, There are countless variations. And I think all of them are dumb.
I think we should all use digits for numbers, ALWAYS, when used in a numerical sense. In other words, in all cases except for the word ‘one’ used in its non-numerical sense, where you’re using it like the indefinite article ‘a’ rather than to specifically count things (Here’s one I made earlier; If there’s one thing I like about rainbows, it’s…) I have a whole article about it: It’s a digital world: Use digits for numbers.
