Gosh, Lulu has a dozen words and phrases at age 1. She uses the dog's name, Hey, No, all in context.
I've seen 25 year old greys with prodigious vocabs, as well.

Parrots are bright, they have amazing cognition and language. But if your CAG sounds like your 5 year old, I'd really worry you had an autistic kid.
