Patricia, A quick glance at the "Index to Modern English" shows that non-personal genitors indeed take appostrophes. Here are some examples from the book: the ocean's roar yesterday's news a stone's throw a dollar's worth Jimmy Backer ----- Original Message ----- From: "Patricia Reifen" <patriciareifen@xxxxxxxxxxx> Subject: RE: [etni] Fw: re: Animal rights Perhaps it's because the apostrophe can only be used with something belonging to a person. eg: " men's rights". However, animals are not people so it is incorrect to say "animals' rights". It would have to become "the rights of animals", - just as one may say "the man's hat' but not 'the roof's colour"!
