When it comes to apostrophes, I get my knickers (not knicker’s, mind you) in a twist whenever I see them being blatantly misused. In the interest of saving the English language from a growing tendency for poor literacy and good txt spk, and really to preserve my own sanity, I prefer to point out errors where I see them instead of letting them go.
After all, how do people learn from their mistake’s if those mistake’s are not pointed out, right? (There was a grammatical test in that previous sentence for you.)
If you work in content marketing, PR, even SEO, you should care about the quality of what you publish. Using my old sub-editing rules as a guide, here’s a summary of how to use apostrophes:
Apostrophes aren’t needed in plurals
Apostrophes are not used in plurals, unless those plurals also show ownership. The most common apostrophe error committed by many people is to use one in words where an “s” is added to create a plural.
One house, two houses (not house’s); one book, three books (not book’s) etc.
Apostrophes can denote omission
Apostrophes are used in place of missing letters, where words are abbreviated. Some examples:
- Can’t (instead of cannot)
- Won’t (will not)
- Hallowe’en used to be spelled with an apostrophe, before it became Halloween, because it is an abbreviation of Hallow Evening – or the eve of All Hallow’s Day.
- T’internet – a colloquial northern expression popularised by Peter Kay.
- Rock ’n’ Roll – note, apostrophes showing the missing “a” and the missing “d” – Some people write Rock ’n Roll, which is silly. Use both or none, depending on your style.
Apostrophes denote possession
Some possessive words, such as hers and his, don’t need apostrophes because they are natural words but when you show possession by adding an “s”, you use an apostrophe. For example:
- Steve’s post (the post belonging to Steve)
- Steve’s appointment at the therapist
- Steve’s chill pill
- And so on.
What if the possession is added to a name that already has an “s” on the end? A good rule of thumb here is to use the phonetics of the word to help you decide whether it should be James’ book or James’s book. How you say the word will signify how to spell it. We say “Jameses book”, phonetically, so we should write “James’s”.
Some other plurals to watch out for:
- 80s and 90s (not 80’s and 90’s) – the full words are eighties and nineties.
- 1000s of pounds – again, it’s thousands, not thousand’s.
Plurals and possession – the apostrophe nightmare
The real nightmare when it comes to apostrophes is where you have a possessive plural. The apostrophe must always come after the plural. Never is the apostrophe more necessary than in this situation, because it changes the whole meaning of a sentence. Consider these examples.
- The books belonging to my sister = My sister’s books
- The books belonging to my three sisters = My three sisters’ books
A quick note about upside down apostrophes
A common error I see in print is committed by writers using modern word processors. If you type a word that begins with an apostrophe, the word processor will automatically assume you are opening a quote. So, you tell ’em, with full curly marks would appear by default like this: you tell ‘em but as an apostrophe that is upside down. If this happens while you are typing, you need to go back and edit the punctuation to change it from an open quote mark to an apostrophe – you tell ’em.
Thank’s for listening. I hope its all been useful.
