Like most four-year-olds, Joey has favorite words. He loves to walk aroudn saying these words, just to feel them in his mouth. I remember doing that as a kid. I really liked the words "squash" and "golden", and remember walking around one day saying "buttercup" just because it felt good. Maybe I'm weird, but I see other little kids doing this all the time, often to the annoyance of their parents. Joey does it, too.
Today's word is "tenacious." He has an idea of what it means, because he loves Pinky Dinky Doo, and "tenacious" is a word they highlight. He's very good at saying it, too. Joey still has a thick quality to his voice (that I can get no therapist to recognize or acknowledge, even when I point it out directly), but its pretty clear and understandable. So he's playing being Pinky Dinky Doo and Mr. Guinea Pig, tooting on a kazoo and joyfully exclaiming, "TENACIOUS!"
