Daughter: "Mommy, I am FEROCIOUS!"
Me: (only half listening) "Oh, really?!"
Daughter: "Yeah. That means that I am REALLY REALLY hungry!"
Me: (long pause as I tune in enough to register the conversation thus far)...."Oh! You mean that you are VORACIOUS!"
Daughter: "...yeah, FEROCIOUS!"
Well, that's still not too bad for the vocabulary of an almost three-and-a-half-year-old.
