Possessive Apostrophe – English editing.

The Apostrophe is used to show that something belongs to someone. For example:
Lord Rochester’s monkey.
The girl’s handbag.
The Brown’s Silver wedding anniversary.
The different churches’ position on gay priests.
As these examples show, the rule is that if the name or noun is in the singular, we add an apostrophe followed by the letter’s’. If the name or noun is a plural ending in ‘s’ then we simply add an apostrophe. (Plurals that do not end in ‘s’ follow the rule for singular nouns: children’s playground.) There is one exception to the rule. When its means ‘of it’ there is no apostrophe.
