Speaking Tampa

Ryder has developed his own language that he calls Tampa. Speaking Tampa involves substituting all the initial sounds in every word. It also includes substituting as many other sounds as he can, sometimes so that you can't even recognize the word he's saying. Though there are a few words that stay the same all the time, most words have a variety of letters being substituted in at different times, so words rarely sound the same twice. Tampa is Tampa-speak for Grandpa. I'm not sure how that became the name of the whole language, but that's what it's called. Here are some typical Tampa names, as those are the words that are most consistent from one time to the next:
Grandpa=Tampa
Mommy=Salami
Carter=Tarter
Ryder=Tyter
Grandma=Handma
Daddy=Patty

I know that verbal play is a sign of all sorts of good stuff, from high intelligence to a strong development of reading skills to creativity. And I try to keep that in mind when it is driving me NUTS when he is substituting every word in a sentence and making it impossible for me to understand him. Seriously, it's a bit excessive. Or a lot excessive. But I try to roll with it.
