ROYAL WE REBALANCE: doctors, esquires, and ranks higher than "the right honourable" can now use the royal we.
YOU NERF: one can no longer use "you" as a generic second person pronoun. those who wish to write such sentences must use "one" or "those who" instead.
INCLUSIVE THOSE: objects you own are "these", objects someone else owns are "those". if you collectively own the objects, they are now "thise" (rhymes with eyes)! "whose toys are those?" "thise are ours!"
