I think it's covered properly in several said string topics (Advanced Said() Strings, Said() Strings - Comprehensive Examples). My problem was due to programatically building the vocab & probably not something that anyone will run into.
In my opinion, I would think twice about changing any of the word classes in the vocab of the template game. There is only one word that comes to mind is the word 'with' (which I've done in the past during testing of the parser), but I'm not even sure if that's a really good idea.
