In a comment to the language evolution post, George suggested adding y'all as the second person plural. While I cringe a little at y'all, he makes a valid point. While English may be said to have more words than any other languages, it is missing some fairly important ones. There is no plural you except invented terms like y'all and yous. There is also a missing third person singular neuter. The formal solution of he/she or one has been tried and just doesn't suffice. We've filled it with "their," at least informally, and this seems to work well.
English has evolved as these issues needed to be addressed and we now have solutions to the problem (you all and their). Perhaps it's time for these to be formally accepted.
