Question: can apostrophe s mean is?
Answer: 1. Use an apostrophe + S ('s) to show that one person/thing owns or is a member of something. Yes, even if the name ends in "s," it's still correct to add another "'s" to create the possessive form. It is also acceptable to add only an apostrophe to the end of singular nouns that end in "s" to make them possessive.
