Apostrophe mistakes are always unacceptable. That’s because they change the meaning of your words. It’s the difference between feeling you’re nuts and feeling your nuts!
The Apostrophe Protection Society agrees, and there’s even an International Apostrophe Day (August 16). One activist in Bristol corrects wrong punctuation on signs at night, vigilante style.
The confusion arises from sometimes contradictory rules, so it’s easy to make mistakes.
3 questions to ask to always get apostrophes right
1. Is it about possession?
Yes? Use one, but do not use one for personal possessive pronouns (its, yours, ours, theirs). Check this table for where to put it.
No? Go to question 2.
2. Is it about contraction (shortening a word or words)?
Yes? Use one, eg. it is = it’s, would have = would’ve, cannot = can’t.
No? Don’t use one.
It’s worth knowing that the possessive ’s comes from showing contraction of the Old English es suffix which made a word possessive (eg. King Richardes crown became King Richard’s crown). So you could say apostrophes are all about contraction. But check question 3.
3. Will not using one cause confusion?
You’d use one for plurals where it could confuse, for example with single letters.
Underline all the a’s and i’s, rather than underline all the as and is.
Don’t use them for acronyms: the UFOs were great DJs.
