Three quick tips to help with its usage:
The humble apostrophe (') is one of English's most commonly misused punctuation marks. With a few simple rules, you can confidently use it like a pro. Let’s break it down with some examples.
Use an apostrophe to indicate ownership.
Singular nouns: The dog’s leash (the leash belongs to the dog)
Plural nouns ending in s: The teachers’ lounge (the lounge belongs to multiple teachers)
Irregular plural nouns: The children’s toys (the toys belong to the children)
Apostrophes replace missing letters in contractions.
Can’t = cannot
It’s = it is (not to be confused with its, which is possessive)
You’re = you are (not to be confused with your, which is possessive)
Apostrophes do not make words plural.
Wrong: Apple’s for sale
Right: Apples for sale
Remember: If in doubt, ask yourself whether the apostrophe indicates possession or replaces missing letters. If not, it probably doesn’t fit!
Mastering the apostrophe may seem tricky, but if you keep these 3 points in mind, you’ll be well on your way to better punctuation!
