Apostrophes with Words Ending in “s”

While normal people wonder about apostrophes in general, believe it or not, word nerds have heated arguments over whether to use an additional s with singular possession. In this newsletter, you will get the standard, most popular decision among authorities.

Rule: To show singular possession for a word ending in an s or s sound, use the apostrophe and another s.

Examples: the class’s opinion (one class), a bass’s stripes, Marx’s theories, Dickens’s novels

Rule: To show plural possession of a word ending in an s or s sound, form the plural first; then immediately use the apostrophe.

Examples: the classes’ opinions, the basses’ stripes, the Williamses’ car, the Soos’ house, the Marxes’ children

Quiz

30 Responses to “Apostrophes with Words Ending in “s””

  1. Scot Says:

    I’m sorry, but Ms. Jones owns a house, hence it is Ms. Jones’ house, etc.

    “Joneses” as such states that more than member of the Jones familiy is being referred to. Adding (incorrectly) an apostrophe paramount to stating “The hot sun is hot.”

    This “new” English or “incorrect English based on general, incorrect usage” is terrible. Or should we all say “He did good” just because so many English speakers use this phrase incorrectly?

  2. Jane Says:

    One could say “the Jones house” using “Jones” as an adjective. One could also say “I saw the Joneses yesterday” using “Joneses” as a plural. However, one cannot say “the Joneses house” without using an apostrophe. This is a plural possessive so “the Joneses’ house” is correct.

  3. Chris Says:

    I have come across one very reasonable exception to the rule for single possessive nouns. That exception states that only an apostrophe should be added to form the possessive of ancient names already ending in the “s” sound to which the addition of another “s” sound would produce a very awkward pronunciation.

    For example:

    Aristophanes’ play
    Pericles’ speech
    Moses’ staff

    Should this exception be widely accepted, or is there another solution for ancient names like these?

  4. Jane Says:

    You are right about this exception, Chris. You could include Jesus in this list:
    Jesus’ teachings

  5. Jane Says:

    Ok, so I get that it is grammatically correct to leave a ‘ AFTER an s in certain phrases. But why? I mean, what if I had a last name like Sussis, or Sessisses? People probably have a name like that, and what do you say then? Saying “I’m going to the Sussis’ house.” sounds like Sussisses! That’s a major mouthful, don’t you think? It’s just an opinion, but I’ve always wondered about that.

  6. Hannah Says:

    It is both correct to use ‘Mrs Jones’ house’ or ‘Mrs Jones’s house’. In different countries, one is more commonly used than the other. For example, in the UK it is more common usage as ‘Mrs Jones’s house’, in Australia it is ‘Mrs Jones’ house’ but either is sometimes used and neither is incorrect.
    When there is a strong s sound to the end of a name, such as Sussis, adding the apostrophe without another s is a simpler and clearer way to go, e.g. ‘The Sussis’ house.’ Writing, ‘The Sussis’s house’ would not be incorrect, just somewhat clumsy, especially for speech. The important thing is the apostrophe to show possessive and whether or not to add another s is one of the few times you can make a choice about the rules of grammar.

  7. Jane Says:

    Hannah, you’re correct that you can write “Mrs. Jones’ house” or “Mrs. Jones’s house.”
    I prefer keeping it simple by suggesting adding the apostrophe and the “s” to all singular possessive names, regardless of the letter they end in.

  8. Helen Mathur Says:

    I teach my students in India the use of the apostrophe for possession by telling them to write down the name of the ‘possessor’, whether singular or plural, then add the apostrophe, and finally add an ’s’ if the sound requires it. I find that this way they do not get confused about, for example, “children’s, princess’s, the Joneses’….”

  9. Jane Says:

    Helen, I agree and also teach this method in the Apostrophe Rules section on my web site, http://www.grammarbook.com.

  10. Melissa C. Says:

    Hi! My question is wedding related. I’m working on RSVP envelopes and they’d like to use i.e. “The Smith’s” , not using the word House afterwards. Is that gramatically correct? They do not want the word “House” used after the last name.

  11. Jane Says:

    “The Smith’s” would never be correct because “The Smiths” should be plural.
    I need more of the context to help you decide between “The Smiths’” and “The Smiths.” If house is implied, you can use “The Smiths’.” Example: There will be a reception at The Smiths’ at 2:00 p.m.

  12. Victoria Says:

    Which is correct–Kirkland and Ellis’ or …and Ellis’s? It’s a law firm.

    Victoria

  13. Victoria Says:

    Which is correct: Kirkland and Ellis’ or Kirkland and Ellis’s (it’s a law firm)?

    Victoria

  14. Jane Says:

    Kirkland and Ellis’s

  15. Miranda Says:

    Hi,

    If I had to label a photo of 3 of my friends who are named “Chris”.. would this be labelled “My three favourite Chris’s…” or “My three favourite Chris’…” or how should I label this?!

    I know usually if it was a singular Chris, we’d use Chris’ ball or Chris’ pencil case, but I’m really confused with the fact there are multiple people with the name Chris!!

    Thanks,
    Miranda

  16. Jane Says:

    With plurals of names, you don’t need apostrophes.
    “My three favorite Chrises”

  17. June Says:

    Which is correct:

    Bob and Joe’s fight

    or

    Bob’s and Joe’s fight

  18. Jane Says:

    Bob and Joe’s fight
    Since they “co-own” the fight, you need an apostrophe only before the second name.

  19. Jeff Braman Says:

    Which use of the word “chapter” is correct in the following sentence:

    I have thirty-one (chapters/chapter’s) in my book.

    Thank you,

    Jeff Braman

  20. Jane Says:

    chapters
    This is a plural usage, not a possessive usage.

  21. Elizabeth Says:

    I have another example that comes up at work frequently. Either I’m consistently getting it wrong, or others are. I work at “Something” Industries. When referring to our facilities, people have written:
    Something Industries facilities
    Something Industrie’s facilities

    I have always corrected them with:
    Something Industries’ facilities

    Please tell me if I am right or wrong. I may be wrong, but if I am, I am not clear on the reasoning. I know you must add the apostrophe to show possession; however, since the word ends in an “s” and “Industries’s” sounds absurd, the only logical solution seems to be the one I suggested.

    I am an executive level assistant in my dept. Many of the people who work with me have BS degrees in health physics or related areas. I don’t think they think I know a thing! As it turns out, I have a degree in Communications (with a concentration in PR). Many of my professors tried to convince me to switch to a major in English, but I really was interested in pursuing a communications profession and felt very confident about my spelling and grammar knowledge. I also graduated summa cum laude, which most people don’t know. It’s just interesting how people assume that, because I am not a manager, I know less about everything than them. Hey, I know stuff!

    They do the technical portion of their proposals and pass them to me. I organize them and make them sparkle. They do the content; I do the magic. :)

  22. Jane Says:

    Elizabeth, you’re right; they’re wrong. Doesn’t it feel good to be validated?

  23. Ashley Says:

    I am giving a door knocker as a gift to a recently married couple… their name is Theos. What is the proper use of plural/possessive? I would think their name would be plural because there are two of them and possessive as it is their house… however I’m struggling with the ending in s?!? And I think a door knoker that reads “The Theoses’” is a bit buch and to me appears to change their last name… Please HELP! Thank you!!!

  24. Jane Says:

    “The Theoses” is correct. If you don’t like the looks of this, you could use “The Theos Family.” No apostrophe is used because it is not a possessive unless you write “The Theoses’ House.” I hope this helps.

  25. Randy Says:

    My son has an “ancient” name: Atticus. Should his possession be Atticus’s or Atticus’ (see above comment: Jane 2/4)?

  26. Jane Says:

    Either is correct. However, I would use Atticus’s for the possessive because you are not referring to the ancient Atticus.

  27. Lauren Says:

    Would it be wrong to write Mrs. Evans’ classroom? Every grammar book I have including MLA materials has contradictory explanations! So frustrating!

  28. Jane Says:

    It is better to write Evans’s to let people know that the original name was Evans. This is not mandatory, however.

  29. Andy Says:

    I think the following example comes down to sounding it out:

    Possessive of “Smith and Williams” (law firm)?

    I know that it could either be Williams’s or Williams’. From what you’ve written and what’s been said in the comments, however, the latter is incorrect as it’s not an ancient name. I think this is a rare exception to this rule. This name when possessive and sounded out is NOT the same as “Kirkland and Ellis’s.”

    Do you agree that “Smith and Williams’” is correct? And is there a rule succinctly explaining why?

  30. Jane Says:

    I agree that Smith and Williams’ is considered acceptable. However, because the name ends in an “s,” one could assume that Williams’ means that the name was William, not Williams. To avoid confusion, I recommend using the apostrophe “s” on all names ending in “s.” I don’t hear any difference between Ellis’s and Williams’s.
