Apostrophes
Apostrophes in general English
Although not acceptable in academic English, you can use an apostrophe in informal writing to show contractions:
- I’ll = I will: I’ll see you tomorrow.
- he’s = he is: He’s an important person in his community.
- it’s = it is/ isn’t = is not: It’s / It isn’t cold outside.
- can’t = cannot: He can’t cope with the pressure of work.
