What is the correct way to put the apostrophe. the doubt is with "stadium" because it starts with 's'.

"United's stadium" or "United' stadium"

PS: I need to know why (with grammatical explanation and reference)


"United's stadium" is the correct spelling, since United is a (one) company and hence thought of as one (singular).

Forming the possessive - EF

To form the possessive, add apostrophe + s to the noun. If the noun is plural, or already ends in s, just add an apostrophe after the s.

  • In this case, it doesn't matter if "United" is singular or plural, because it doesn't end in "s" anyway. Even if you'd say "Manchester United are playing today", you'd say "Manchester United's stadium is empty". – V2Blast May 8 at 20:32

The possessive clitic is almost always 's. The only exceptions are plurals already ending in -s (eg the boys' caps), and some names ending in -s (eg James' book).

So there is always an "s" either before or after the apostrophe (rarely both).

Those rare plurals which don't end in -s take the usual 's (eg the children's caps), so even if you choose to treat United as plural (which British English often does) the possessive clitic is still 's.

    For singular proper nouns ending in s, it's a matter of style; The Chicago Manual of Style goes with James's. – Tinfoil Hat May 8 at 20:13

    @TinfoilHat: yes, I decided to ignore that issue, since it doesn't affect my answer. – Colin Fine May 8 at 20:15
  • It's common—not rare—to have an s both before or after the apostrophe—if you account for names ending in s. – Tinfoil Hat May 9 at 14:37

"United's stadium" is the stadium belonging to "United". "United Stadium" is the stadium which bears that name. "United' stadium" is improper punctuation.
