I understand 's means is and has, if 's is used at the end of a name, Does it mean is or has?Let's suppose Ex is a someone's name.

Ex is object -it can mean Ex is an object, totally incorrect

Ex has object -incorrect grammar and it does not refer to have something

What does 's really mean? What is the no-contraction mode of name_of_a_person's?

  • -'s forms the possessive: i.e. John's car might be rephrased as the car of John or the car belonging to John. – Anonym Mar 17 '16 at 3:56

When it's not a contraction it's about possession. But it's really not that simple. Here's a source that attempts to explain all the cases.

Apostrophes with Names Ending in s, ch, or z
Are you confused about how to show the plural and the possessive of certain names? Maybe you know to write I met the Smiths, I drove Brenda Smith’s Ferrari, and I visited the Smiths’ house. But what if the name is Sanchez or Church or Williams?

Rule: To show the plural of a name that ends with a ch, s, or z sound, add es. If a name ends in ch, but is pronounced with a hard k sound, its plural will require s, rather than es.

The Sanchezes will be over soon.
The Thomases moved away.
The Churches have arrived but the Bohmbachs are running late.

Rule: To show singular possession of a name ending in ch, add ’s on the end of the name.

Harry Birch’s house

Rule: To show singular possession of a name ending in s or z, some writers add just an apostrophe. Others also add another s. See Rules 1b and 1c of Apostrophes for more discussion.

Bill Williams’ car OR Bill Williams’s car
Mrs. Sanchez’s children

Rule: To show plural possession of a name ending in s, ch, or z, form the plural first; then immediately use the apostrophe.

the Williamses’ car
the Birches’ house
the Sanchezes’ children


But it's not even that simple as explained in: Is “ ’s ” ever correct for pluralization?

And the name itself can change the way you should show possession, as explained here: Which singular names ending in “s” form possessives with only a bare apostrophe?
