How foolproof is your spellchecker?

Using a spellchecker is a convenient way to quickly check and correct errors in a text. Running it over your email before you send it or over your blog post before you publish it is highly recommendable. But does it find all the mistakes?

A spellchecker is ‘a computer program which checks the spelling of words in files of text, typically by comparison with a stored list of words’ ( And therein lies the weak spot: it checks against a list of words. So what about words that are on that list and spelled correctly – but not where you want them? Have a look at the following ten examples that would pass a spellchecker with flying colours. Can you spot the error in each of them?

Have a go – beat the spellchecker!

1. Could you send me the text in an edible format?
2. During a conversion between three or more people, one person often unwittingly takes on the role of the moderator.
3. After giving birth, all he wanted was to hold her baby in her arms.
4. We are happy to except your offer and look forward to working with you.
5. It was all – in all – a successful launch.
6. ‘Let’s eat nan,’ she said, and sat down at the table.
7. The company is implementing the changes across all sectors and it’s ever expanding network of suppliers.
8. A fixed space can be used to keep two words together that is separated by a space.
9. Do something great – everyday!
10. By spotting only one the ten errors, you have already beaten the spellchecker.

A spellchecker is not a proofreader

It is easy to be lulled into a false sense of security with a spellchecker. After all, it is supposed to check your spelling, so you would think that it will find any mistake. But as you can see in these examples, a spellchecker cannot find the error if the spelling of the word in the text matches the spelling of the word on its list. It cannot tell if a word is missing or in the wrong place. No wonder – it is only a program and cannot read and understand the text as such.

Human proofreaders, on the other hand, not only check spelling and grammar, they also read the text for sense. They don’t just look at the individual words but at the whole picture. This is why a trained proofreader can spot correctly spelled words in the wrong context and other inconsistencies. So if you really want to be on the safe side, don’t just rely on a spellchecker – run it past a proofreader as well.
