Apostrophes

With possession

example explanation correct use
the cats more than one; no possession The cats are prowling at night
the cat's belongs to one The cat's bell has fallen off
the cats' belongs to more than one (plural ending in s) The cats' beds were in the laundry
the children's beds belongs to more than one (plural not ending in s) The children's beds were still unmade.

With pronouns

All pronouns except it have a specific plural form. None of them takes an apostrophe:

my place; your place; his place; her place; its place; our place; their place.

With contractions

Apostrophes are used to indicate contractions (missing letters): that's reasonable; don't go; it's raining .

Common errors

Confusing the possessive pronoun its, with the contraction it's (it is): the dog chased its tail; it's a long tail.

Using the possessive pronoun your (belonging to you), instead of the contraction you're (you are): you're invited; your mistake was to think you're not welcome.

With plurals

Apostrophes are not used to indicate plurals: PDFs, not PDF's; 1980s, not 1980's; fruit and veges, not fruit and vege's.

With Australian placenames

Australian placenames involving possessives are all written without apostrophes: Kellys Creek; Logans Crossing; Batemans Bay.
