What is the Possessive ‘s for?

The possessive ‘s is a small but powerful part of English grammar. We use it to show ownership or a relationship between a person and a thing.

• It answers the question “Whose is it?”
• It tells us who something belongs to.

Think of it as a shortcut to say “the book of John” or “the car of my father.”

How do we form the Possessive 's?

It is very simple to form the possessive 's with singular nouns and names.

• Take the name of the person or the singular noun.
• Add an apostrophe (') and then the letter s.
• Then, add the thing they own.

Look at these examples:

Possessive 's with Names

When someone's name is singular, we add 's to the end of their name.

• This is Mary's bag. (The bag belongs to Mary.)
• That is Tom's ball. (The ball belongs to Tom.)

Even if a name ends in s, 例えば James, we still add 's. For example: James's car.

Possessive 's with Singular Nouns

また、当社は 's with singular nouns that are not names, like teacher または dog.

• This is the teacher's desk. (The desk belongs to the teacher.)
• That is the dog's bone. (The bone belongs to the dog.)

Remember, this rule is for singular nouns only. We will learn about plural nouns later.

例

• This is Anna's pencil.
• That is my father's car.
• Where is the cat's toy?
• Is this Peter's book?
• The girl's hat is red.

スペイン語話者がよく犯す間違い

Spanish speakers sometimes make these mistakes:

• Using "of" instead of 's: In Spanish, you might say "el libro de Juan." In English, we use 's.
  • 誤り： The book of John.
  • 右： John's book.
• Forgetting the apostrophe: The apostrophe ' is very important. Without it, Johns book looks like a plural word, not a possessive.
  • 誤り： This is Marias bag.
  • 右： This is Maria's bag.
• Confusing it's そして its: It's とは it is または it has. Its is a possessive pronoun (like his または her).
  • 誤り： The dog wants it's bone.
  • 右： The dog wants its bone.
  • 右： It's a big dog. (It is a big dog.)
