Possessives

A possessive noun is a noun that show ownership.

When we want to show that something belongs to somebody or something, we usually add 's to a singular noun and an apostrophe (') after the s for a plural noun.

For Example: "Those are Bruno's books"

"That is the Ferrufinos' cat"

If the word is a plural noun but ends in a letter different than "s" then you use 's

If a word is a singular noun and ends with the letter "s", we still add 's
