Plural possessive form of athletics - Computers & Internet

exes
An apostrophe makes it a possessive, not a plural.

The plural of "dog" is "dogs." The possessive is "dogs' ."

singular: incumbent's
plural: incumbents'

It is a common noun used in a possessive sense, eg "the boat's deck". As such it often involves adding an apostrophe-s to the noun. Where the noun already ends in an s, just the apostrophe may be added eg "the cars' exhaust fumes" for more than one car. The noun may have some other plural form, and we go back to the basic rule eg "the mice's cages".

Possessive Form of a noun.
To express possession one appends an apostrophe followed by s ('s). That is the possessive form of the noun.
The paw of the tiger : the tiger's paw. Tiger's is the possessive form of the noun tiger.
When the noun is a plural ending in s, the possessive form could be ...s's or ...s'. Both forms are correct. If you are a student and your teacher insists on using one form rather than the other, do as you are expected. Once you start writing your own books, use the form that pleases you. It is just a matter of usage, and usage is changing all the time.

There is no such thing as a possessive noun.
The real question should be : What is the possessive form of a noun? How do you show possession (ownership) relating to some noun?
To express possession (ownership) in English one appends an apostrophe (') followed by s. To append is to put at the end.
The nose of the moose can be expressed as the moose's nose.
The rule is straightforward. When the noun to which the ownership refers is in the plural, the rule can be applied as stated above append ('s). However if the mark of the plural is s (regular plural) some people want to use the rule above, some others say that the last s should not be appended..
Example: The hind legs of the wolves can be expressed as the wolves's hind legs or the wolves' hind legs. In the first expression you have wolves's while in the second you have wolves'.
Both rules are correct, but nowadays the tendency is to use the second form. It is a matter of usage.
If you are a student follow what your teacher says. When you write your own books, choose the one you want, but if your editor insists on using the other one, you have a problem.
