Yes, I'm with 'Neato and Grin. I don't hear much about "precocious" at all in discussions/books about giftedness. I think Grinity's definition is the one I would use, but only after really thinking about it. Precocious just isn't a word I see often and isn't a word I would use in any discussion of GT kids.

I don't think precociousness is necessarily related to GTness, nor would I use it in that context. If you mean GT, I think you say GT.
