Possessive Nouns with Apostrophes
Using possessive nouns with apostrophes can be a little bit tricky to work out.
Sometimes words appear to be in the possessive case but there is no real ownership, such as:
- a month’s pay ["month" is singular, so apostrophe comes before the "s"]
- two days’ washing ["days" is plural, so apostrophe comes after the "s"]
- yesterday’s appointments ["yeserday" is singular, so apostrophe comes before the "s"]
- last year’s bank statements ["year" is singular, so apostrophe comes before the "s"]
- two years’ receipts ["years" is plural, so apostrophe comes after the "s"]
- girls’ underwear ["girls" is plural, so apostrophe comes after the "s"]
Although it looks like there is ownership, it is really called “False Possessive”, and yes an apostrophe IS required in these instances.
NOTE:
- You put the apostrophe after the *s* when the word is plural, as in examples above – Items 2, 5 + 6.
Just remember, not everyone knows how to do this apostrophe thing … even I have to stop and think sometimes, to make sure I get it right. There’s nothing wrong with looking it up online … don’t forget to come to the Humble Apostrophe if you’re not sure where to put your apostrophe, punctuation or parts of speech!
