"vocabulary"

We were listening to Hannity recapping the debates this afternoon while driving to volleyball...

Radio (paraphrase):  Mitt Romney showed that he was confident and articulate...
Emma:  HEY! I know what 'reticulate' means!  It means to speak clearly and people can understand what you're saying.
Mama:  Yes, Emma.  That is what articulate means.  Good job!
Emma:  [Nods]... yeah, WordGirl  (show on pbs kids).
Mama:  Wow, she really helps us with our vocabulary doesn't she.
Emma:  Yep! AND she teaches us new words and tells us what they mean!
