1. Apostrophes in essays (‘) have two functions. They indicate both the possessive case and contractions. This might seem simple, but apostrophes cause a lot of problems.
The Possessive Case
2. We can say either ‘the whiskers of the cat’, or ‘the cat’s whiskers’. This is the possessive case, when something belongs to somebody or something else.
3. When the possessor is single we indicate possession by using an apostrophe followed by the letter ‘s’:
The man’s coat my sister’s hat.
4. When the possessors are plural, the apostrophe is placed after the final ‘s’:
The girls’ bicycles my cousins’ parents.
5. When names end with the letter ‘s’, either use is acceptable:
James’ wife or James’s wife.
(It is often said that the choice between the two should be made on how the word is pronounced.)
6. The apostrophe is never used with possessive pronouns:
his, hers, its ours, yours, theirs
But it is used with ‘one’: One must do one’s best.
7. Many shops and business concerns these days omit the apostrophe from their titles:
Barclays Bank Coopers Wines
8. Note that the apostrophe is not required where a word has been formed by omitting its first part:
bus – NOT – ‘bus
phone – NOT – ‘phone
in the 1920s the roaring twenties
10. The possessive of classical names ending in es is often formed by the apostrophe alone:
11. French names ending in an unpronounced s or x follow the normal rule, taking an apostrophe and an s:
Rabelais’s comedy Malraux’s novels
12. In formal prose we would write ‘She has told him’, but when speaking we would say ‘She’s told him’. The apostrophe is used to indicate the missing letters.
I am (I’m) He is (he’s) You are (You’re)
13. Note the difference between it’s (it is) and its (belonging to it).
14. There is no such thing as its’.
15. It’s may also be a contraction of it has
“It’s been a pleasure meeting you”
16. You should avoid the use of contractions in essays and formal writing.
