How is 「の」 used in 終わりのない?


I understand that 「の」 can be used to indicate possession or to change a noun
to a modifier for another noun. But neither of those seems to be the case
here.

What usage of 「の」 is being used here?




終わりのない is not a complete sentence. This phrase can be used as a _relative
clause_ which modifies another noun.

>   * 終わりのない話 a story which has no end; a never-ending story
>   * 終わりがない話 a story which has no end; a never-ending story
>

As you can see, this type of の is a subject marker (just like が) which can be
used only in relative clauses.
