Usage Notes

Why is it "Socrates' Deathbed" but "Dickens's Novels"?

A guide to names in their plural and possessive forms

The plurals of last names are just like the plurals of most nouns. They typically get formed by adding -s. Except, that is, if the name already ends in s or z. Then the plural is formed by adding -es.

the Smith clan → the Smiths

Jill and Sam Clarence → the Clarences

Mr. and Mrs. Jones → the Joneses

the Fernandez family → the Fernandezes

socrates death or socrates death

"And remember—it's Socrates' deathbed, but Zeus's lovers."

Unlike regular nouns that end in y, names that end in y are also made plural by adding -s:

the Kennedy clan → the Kennedys

the Daley family → the Daleys

If you want to talk about something that belongs to more than one member of a family, you start with the plural form and add an apostrophe to show possession:

the Smiths' car

a party at the Fernandezes' house

the Daleys' driveway

If you want to talk about something that belongs to a single person being identified by last name, you follow the usual -'s rule for most names:

the car that belongs to Smith → Smith's car

For names that end in an s or z sound, though, you can either add -'s or just an apostrophe. Going with -'s is the more common choice:

the car that belongs to Jones → Jones's car or Jones' car

But there are a few exceptions. For classical and biblical names with two or more syllables ending in s or es, you usually just add an apostrophe. If the name is only one syllable, add -'s.

Socrates' students

Ramses' kingdom

Amos' prophecy

Zeus's warnings

The names Jesus and Moses are always made possessive with the apostrophe alone:

Jesus' disciples

Moses' law

The usual way to show possession with a name that ends in a silent s, z, or x is with -'s.

Didier Deschamps's career

Josquin des Prez's music

Eugène Delacroix's paintings
