Sorry for instrusion, but both you and Lysandra mistake pronouns for adjectives. Yes, morphologically and syntactically lots of pronouns and numerals too (think ordinal numerals) behave like adjectives, but that doesn't mean they are adjectives. The semantics matter. Although I know OLD itself is not very strict here, but that doesn't change the fact. I would just wish people stopped calling these adjectives... we can do better than that, can't we.
