An apostrophe followed by an “s” is used in English to create possessive nouns. For example, the noun dog becomes dog’s when you refer to something belonging to the dog, such as “the dog’s ball.” With plural nouns ending in “s,” you add the apostrophe after “s” and do not add an additional “s.”

Here are the rules that will apply: Rule one: If possessive noun is singular, then you need to add apostrophe plus “s”. Rule two: If possessive noun is not ending with the letter “s”, then you always need to add apostrophe plus “s”. Rule three: If possessive noun ends with the “s” and it is plural, what you only need to do is to add apostrophe.

The rules about forming possessive nouns probably cause the most apostrophe confusion. They vary a bit, depending on what type of noun you are making into a possessive. Here are the rules of thumb: For most singular nouns, add -’s: The dog’s leash The writer’s desk The planet’s atmosphere For most plural nouns, add only an apostrophe:

In written English, the way we generally express possession is by adding an apostrophe and an “ s ” to a noun. Thus, the bicycle that belongs to Rico would be “ Rico’s bicycle. ” If Tammy has a new boyfriend named Mitch, then Mitch would be “ Tammy’s boyfriend. Possession is to be understood broadly, not limited to physical objects or people.
