Pet peeves, apostrophes, and plural family names

What's the difference between plural and possessive? When is it correct to use apostrophes when writing last names?

Pet Peeves

Do you have a pet peeve?

You know, those annoying little things that don’t seem to irritate anyone else, but drive you positively insane?

I actually found a site——that lists 500 pet peeves, including:

  1. People who whistle when they are happy.
  2. Greeting cards that throw sparkles, sequins or confetti on the hapless recipient.
  3. People [who] don’t use coasters.
  4. Keeping your Christmas lights up until February.
  5. People who dress their pets.
  6. Leaving the toilet seat up.
  7. Cracking your knuckles.
  8. Road maps that aren’t folded correctly.
  9. People who talk on their cell phone at the movies.
  10. Things sticking out of drawers.

I admit that the items on this short list draw different reactions from me. I think it’s silly to dress a pet, for example, but I wouldn’t call it a pet peeve. I can take or leave an incorrectly folded map. And I don’t mind happy whistling at all!

No, for something to qualify as a pet peeve, it has to drive me absolutely batty. Nuts. Fingernails-on-a-chalkboard crazy.

I have several—as do you (admit it). But let me introduce you to just one of them: the misplaced apostrophe.

The apostrophe has two uses: contraction and possession. Unfortunately, people are so totally confused that they’re always sticking random apostrophes where punctuation marks should fear to tread:

  1. In simple plurals, such as “No pet’s allowed” (should be “No pets allowed”)
  2. In family names when referring to the family as one unit, such as “The Wilson’s live there” (should be “The Wilsons live there”)

Do You Know the Johnson’s Johnsons?

One of these days I’ll write up a lesson on plurals vs. possessives. Today, let’s focus on family names.

Watch out when using apostrophes with last names! Grammar guides can differ on how to use apostrophes, but if you follow these rules, you’ll get it right.

One Person’s Last Name

To show possession of one person, add -’s.

Sarah Smith: Mitts is Sarah Smith’s dog.
Jared Jones: Heinz is Jared Jones’s dog.
Reid Roberts: Arrow is Reid Roberts’s dog.

Last names that end in -s can be tricky!

Right: Arrow is Reid Roberts’s dog.
Wrong: Arrow is Reid Robert’s dog.

Don’t use an apostrophe when you mean to make a plural.

Right: The Smiths also want a gerbil.
Wrong: The Smith’s also want a gerbil.

The Whole Family’s Last Name

To show possession of a whole family: First, add -es or -s to write the family’s last name in plural form. Then, add an apostrophe at the end to show possession.

Right: Pip belongs to the Joneses. Pip is the Joneses cat.
Wrong: Pip belongs to the Joneses. Pip is the Jones’s cat.

Right: Jet belongs to the Smiths. Jet is the Smiths cat.
Wrong: Jet belongs to the Smiths. Jet is the Smiths’s cat.


Single person: Mike Miller
Whole family: The Millers
Family’s Possessive: The Millers’ hamster

Single person: Hubert Sing
Whole family: The Sings
Family’s Possessive: The Sings’ parakeet

Single person: Gladys Sanchez
Whole family: The Sanchezes
Family’s Possessive: The Sanchezes llama

Single person: Mrs. Sanders
Whole family: The Sanderses
Family’s Possessive: The Sanderses’ goat

Put it into Practice: Want to give yourself (or your kids) some practice forming plural and possessive last names? Just pull out the phone directory, open to a random page, and give it a whirl! The more they practice forming plurals and possessives, the more natural it will become for them to do so correctly.

    One of my grammar pet peeves was heard on the radio this morning on my way to work. The traffic congestion following a very serious accident was referred to as a fatal investigation. I didn’t know that investigations could be that dangerous.

    My big grammar pet peeve is people who can’t seem to correctly use then and than. They mean two different things and are not interchangeable!!

    Andy: Funny!

    Chrissey: So true. I’m also grieved by misuse of its/it’s, your/you’re, and their/there/they’re.

    People (and there seem to be a lot of them on Facebook) who confuse “lose” and “loose” – drives me batty!

      “Lose” and “loose” — that’s another good one!

    If I hear one more person say “lay down” instead of “lie down,” well, I’ll just have to bite my tongue. Over the decades, somehow people have just stopped saying “lie.” You LAY carpet or bricks, you don’t “lay” down. Unless, of course, you’ve got some duck feathers that you’re setting down somewhere. “Lay” is also the past tense of “lie”.

    Another one for me is “broke” and “broken.” If something doesn’t work anymore, it’s BROKEN. If it’s “broke,” then I guess it’s out of cash?

    Thanks for letting me vent!

      And to piggyback on your own peeves, Peggy, I just read that it’s now acceptable to use “alright” instead of “all right.” Really? Say it isn’t so!

    Recently, I went to school to up grade my accidemic skills. There we covered Concreate nouns and abstract noun, along with common, proper collective, and compound nouns. Rather difficult to learn.

    I hear you, Jody. Grammar can be confusing. It takes a lot of practice to master the different skills.
